Abstract:
This thesis explores the use of computer vision to facilitate three different processes of a quarry's operation. The first is the blasting process. This is where operators determine where to drill in order to execute an efficient and safe blast. Having an operator manually determine the drilling angles and positions can lead to inefficient and dangerous blasts. By using two cameras, oriented vertically, and separated by a fixed baseline, Structure from Motion techniques can be used to create a scaled 3D model of a bench. This can then be analyzed to provide operators with borehole locations and drilling angles in relation to fixed reference targets. The second process explored is the crushing process, where the rocks pass through different crushers that reduce the rocks into smaller sizes. The crushed rocks are then dropped onto a moving conveyor belt. The maximum dimension of the rocks exiting the crushers should not exceed size thresholds that are specific to each crusher. This thesis presents a 2D vision system capable of estimating the size distribution of the rocks by attempting to segment the rocks in each image. The size distribution, based on the maximum dimension of each rock, is estimated by finding the maximum dimension in the image in pixels and converting that to inches. The third process of the quarry operations explored is where the final product is piled up to form stockpiles. For inventory purposes, operators often carry out a manual estimation of the size of a the stockpile. This thesis presents a vision system capable of providing a more accurate estimate for the size of the stockpile by using Structure from Motion techniques to create a 3D reconstruction. User interaction helps to find the points that are relevant to the stockpile in the resulting point cloud, which are then used to estimate the volume.<br>Master of Science

Abstract:
The significance of Yesemek Stone Quarry and Sculptural Workshop in Gaziantep Islahiye province is rooted in its basalt quarry and stone sculptures found at the site. Yesemek was first discovered by Felix Von Luschan in 1890 while he was excavating Zincirli (Sam&rsquo<br>al). Between 1958 and 1961, the site was excavated by a team under the leadership of Prof. Dr. Bahadir Alkim. The excavations at the site yielded approximately three hundred finished or unfinished lion, sphinx and mountain god sculptures. While the exact function of these sculptures are still not known, the thesis will explore the function of these sculptures by examining the architectural structures where the sculptures could have been used as architectural decoration. Another issue that will be discussed in the thesis is the date of Yesemek workshop and sculptures. To that end, Yesemek sculptures will be stylistically compared to Late Bronze and Iron Age sculptures.

Abstract:
The Carnegie Quarry in northeastern Utah is world-renowned for the dinosaur skeletons it has produced and for its in situ display of dinosaur bones. The specimens excavated at Carnegie Quarry are displayed and curated in 20 repositories, most in North America. Data on these specimens in the forms of notes, photographs, publications, field maps, and so on, are scattered in an array of formats and institutions. The primary goal of this thesis is to develop a database linking these data with a digital map (GIS system) to make them readily accessible. To this end, a relational database was created using Microsoft Access linked to a vector-based map developed using Avenza MAPublisher running in Adobe Illustrator. Analyzing these data, the Carnegie Quarry produced 4146 specimens representing at least 105 individuals pertaining to 18 genera; 12 dinosaurs, one crocodylomorph, two turtles, Unio utahensis (a freshwater clam), and one plant. The map is based on high resolution photographs of the current quarry face merged with historic maps of previously excavated portions of the quarry. Previous attempts to develop a complete map were hindered by the large number of maps, primarily from four institutions that excavated at the site, and the lack of an accurate map of the current quarry face (due to substantial relief, the 67° dip of strata, and the lack of a permanent grid). The new maps will provide invaluable insights into the depositional setting, taphonomy and paleoecology of the site. The map and database provide a single access point for data on specimens from 20 widely dispersed repositories linking them their original quarry positions. This expandable tool will be invaluable to scientists and the caretakers of Dinosaur National Monument and is recommended for adoption at other quarries.

Abstract:
This thesis project came out of an idea that architecture can serve to understand the transformation and history of place. In other words, can architecture be interpreted to give opportunities for displaying glimpses of the past, almost like occasional flashbacks? Based on this idea, I designed a building to make this idea tangible and to test the veridicality of my intention. In looking for a site, I sought out interesting places and moments in nature that would convey this idea I was studying. A quarry in Blacksburg, Virginia, an open-pit mine where dimension stone, sand, gravel and slate were excavated, provided me with an opportunity to explore this idea. The building I designed would help to display the original state of this old quarry, now half-filled with water. I started researching the history and development of stone quarries in order to understand essential and accidental connections associated with the present. The overall organization of the building forged a relationship with the surrounding nature and the contour of the mountains. The whole building was sunken into the edge of the cliff to reduce the appearance of the building's volume from the entrance. The slope was utilized to coordinate with the building. The water became a thread that articulates a person's progression throughout the building. The main entrance was at the top of the slope, with a path that leads down the slope along the building to a platform with a view of the site and temporary outdoor exhibits, which allows also for a more immediate interaction with the water. The building responded to the depth of the quarry, bringing it below the surface of the water. The shadow pool of water, trickling down below, draws attention to the curved staircase. Once reaching the bottom level, you can see the water running slowly along the vertical concrete wall. At this point, you enter the exhibits on the general history of stone quarries and the specific history of this stone quarry. Stone samples and tools used in the old times are also displayed on this floor. The second and third floors are collections of modern conditions of stone quarries as well as possible future technologies. The building was conceived as a composition of basic elements, with visual reference to rectangular and circular shapes, and interstitial space enclosures cast in concrete. The choice to use concrete was based on its ability to take flexible shapes and to be enhanced by repeated elements representing natural state of the quarry, as well as an approach to emphasizing light and volume.<br>Master of Architecture

Abstract:
In the previous years, 3D imaging has found his way into the world of Egyptology. This lecture will present two case studies where 3D technology is used for the documentation of hieratic inscriptions. The inscriptions, painted in (red) ochre or black paint, were applied on different carriers, and required a different methodology. The Egyptian collection of the Royal Museums of Art and History (RMAH Brussels) contains a large number of small decorated and/or inscribed objects. Some of these objects are currently in a bad condition - any operation carried on them can result in considerable material losses -, making it necessary to document them in such a way that it allows future scholars to study them in detail without handling them. The EES Project therefore aims to create multispectral 3D images of these fragile objects with a multispectral ‘minidome’ acquisition system, based on the already existing system of the multi-light Portable Light Dome (PLD). The texture/colour values on the created 2D+ and 3D models are interactive data based on a recording process with infrared, red, green, blue, and ultraviolet light spectra. Software tools and enhancement filters have been developed which can deal with the different wavelengths in real-time. This leads to an easy and cost-effective methodology which combines multispectral imaging with the actual relief characteristics and properties of the physical object. The system is transportable to any collection or excavation in the field. As a case study, the well-known Brussels “Execration Figurines” (Middle Kingdom, c. 1900 BC) were chosen. These figurines are made of unbaked clay and covered with hieratic texts, listing names of foreign countries and rulers. The study of this type of collections is mostly hampered by the poor state of conservation of the objects, but also by the only partial preservation of the ink traces in visible light. The method has also been applied to other decorated objects of the RMAH collection, such as a Fayoum portrait, ostraca and decorated objects made of stone, wood and ceramics. The final goal will be to publish the newly created multispectral 3D images on Carmentis (www.carmentis.be), the online catalogue of the RMAH collection, making them accessible to scholars all over the world. The second case study presents the quarry inscriptions of the New Kingdom limestone quarries at Dayr Abu Hinnis (Middle Egypt). These gallery quarries contain hundreds of hieratic inscriptions, written on the ceiling. The texts are mainly related to the general administration of the quarry area. In documenting the abundance of ceiling inscriptions and other graffiti, we had to decide upon a practice that would allow not only to capture the \"content\", but also to document the location and orientation of each record. Every inscription can be photographed in detail, but this is insufficient to provide the reader access to vital information concerning the spatial distribution of the inscriptions, which may, for instance, relate to the progress of work. After experimenting with a variety of other methods, we adopted a photogrammetric software for 3D modelling photographs of the quarry ceilings, AGISOFT PHOTOSCAN, which uses structure from motion (SFM) algorithms to create three-dimensional images based on a series of overlapping two-dimensional images. The ultimate goal of this whole labour-intensive process in the quarries is not the creation of pure threedimensional models, but rather to generate an orthophoto of the entire ceiling of a quarry. Based on these images, each graffito could be analysed in context.

Abstract:
Establishment and operation of quarries causes a number of different environmental impacts. The most important of these impacts affects the visual quality of landscapes. It is caused by the destruction of the visual form and character of the landscape. In such cases, reclamation of the quarries has been found to enhance the visual quality of the landscapes. Another factor that influences visual quality of quarries is the distance from which they can be seen. Because of the large size, quarries, particularly modern ones, can be seen from near to distant viewpoints (Ramos & Panagopoulos, 2006 ). Besides their size, the extent of their visibility depends on, contrast with the surrounding landscape and location relative to other features in the landscape. The main objective of this research is to establish people's perception of the attractiveness of reclaimed limestone quarries in England. The study attempts to do so through public perception-based approaches to landscape visual quality assessment. Specifically, the research aims to assess different limestone quarry reclamation treatments in order to establish the types of quarry treatments and landscape characteristics that were perceived to be attractive. The study also aims to establish how distance affects perceived attractiveness of the reclaimed quarries, while also providing those tasked with designing reclamation schemes with guidance about the relative attractiveness of different reclamation schemes. Ten different scenarios of reclaimed quarries were simulated using different reclamation techniques and different land uses. From these simulations, fifty still images were captured at different distances along an established transect. Also, Ten animations were recorded along the same transect. These were used in a survey of seventy students having different backgrounds from the University of Sheffield. The images were presented one at time through a data projector to each individual participant. The participants were asked to rate the quarry landscapes on their attractiveness and also to note different landscape characteristics that influenced their ratings for each scene. It was found that participants liked scenes that contained water and trees the most and those that had plain landscapes and highly visible rock the least. It was also concluded that the relation between distance and attractiveness of reclaimed limestone quarry landscapes had a negative correlation coefficient. For the majority of scenes, there was no significant difference in how participants from different academic backgrounds perceived the attractiveness of the quarry landscapes.

Abstract:
Today’s quarries face a change in the operational processes, where the development of automated transport systems and machines have intensified the necessity for reliable and stable data transfer. Within the dynamic environment, with piles building up suddenly, frequently changing mining faces due to blasting, as well as a frequently changing general environment that affect the network coverage negatively, there is a need for a solution that can adapt to the changing environment. The aim of this research has been to investigate the requirements for a dynamic infrastructure, and develop a platform based on today’s available technical solution components that can act as a dynamic platform for the evolving autonomous quarry. This by also reducing the time the worker is exposed to the harsh environment that the quarry presents. The research was conducted through a combination of a product development strategy and Design Research Methodology to develop a concept that fulfills the customer needs that are identified. An iterative process, where the needs were translated in to prototypes, has created learnings through every step of the development process. The result is a relocatable platform for communications relay, which is mounted on a trailer with a fixed mast to distribute short-wave communications in the area where the mobile unit is needed. The trailer is equipped with a four-point leveling system that also act as a stabilization system for the unit and ensures that the platform maintains a horizontal plane at all times. This platform is a first step towards a fully autonomous management of the communication infrastructure which in the future will be needed when a stable process and connection is necessary in the frequently changing environment. The relocatable platform is a necessity for adaption of the short-wave communication in the constantly changing environment. Since this is a first iteration and concept in the development of a dynamic platform, extensive field tests are required to determine which subcomponents are in need of further development or optimization. The completed prototype for the platform is functional and field ready for further testing in its real environment for further collecting of data points. This concept is a subcomponent of a larger system, where the goal is to increase the productivity and reduce the environmental impact from today’s quarry industry. Through reduction of human interaction and management of the relocation of the mobile unit, the workers safety is increased and the harsh environmental exposure is reduced.

Abstract:
Every place on earth has a voice. This voice resonates from the shaping events that have long passed and the current conditions that continue to give each place its individual character. The voice continually evolves as the cycle of birth, death, and rebirth leaves its trace. This voice in its endless variety of forms expresses the beauty that is inherent within each and every location on earth. The potential of architecture is the translation of this voice into human terms and the formal declaration that we as humans play a meaningful part in the cycle. The guiding forms, surfaces, substances of architecture allow the human body to move in grace, unhindered, and inspires the mind to sense the essential connection between matter spirit; between the individual and the whole. The role of the architect is to become sensitive to this voice; to silence the mind enough to hear, and to respond to it in material form. The resulting dialogue between the edifice and the encompassing site reaches a certain completeness that enriches the living experience of the end user, bringing the wandering mind to the present long enough to inspire the thought that "I belong here, among all of this." The technical training required in order to gain an inherent understanding of structure and materials takes years of experience in the field of architecture. However, it has been the focus of my graduate career to further develop this sensitivity to the site and make my first attempts at formulating an architectural response, suggesting structures that could achieve this engagement with the end user and the site itself.<br>Master of Architecture

Abstract:
My study consists of an inquiry into archaeology and palaeontology, and the relationship of 'the dig' to landscape. I focus on the idea that digging or excavating is a process that can reveal ancient landscapes and suggest new narratives. My research revolves around ruin discourse, and the idea that a 'dig' is a sort of ruin in reverse. I began thinking about the criteria that define a ruin and applying them to landscapes. The study culminated in the idea of the landscape being a kind of ruin itself; the experience of a ruin, or ruinenlust, isn't only about a structure that has been dragged down into the ground over time- it's also about light, temperature, plants, views - all the elements that make up our experience of landscape. I set about trying to turn this study into a project - how do I design the idea that all landscapes are ruins? The ideas I had explored of excavation, and especially the image of the 'grid' of excavation as an imposition over the landscape, led me to the Higgovale Quarry site.

Abstract:
Limestone and dolomite quarries were mapped to determine specific slope failure mechanisms for the various geological and structural conditions. Wedge failure and plane failure were determined to be the most influential mechanisms. Algorithms for analyzing these mechanisms were incorporated into the software package PSLOPE. The program is designed to facilitate progressive stability evaluation of quarry high walls as mining continues and permits calculation of safety factors and probabilistic reliability. Safety factor evaluations with the potential for back-analysis and sensitivity studies are included to investigate alternative high wall designs. Reliability analysis using Monte Carlo sampling minimizes uncertainty and allows the use of all available data in a stability evaluation. E~tensive "help" menus are incorporated into the program. The "help" menus include ranges of physical properties such as cohesion and friction angle for specific lithologic units determined from published research. This package includes an optimum design protocol that can be followed to avoid massive failure. The program was developed in conjunction with the quarry industry and is demonstrated through technical problem solving and a detailed case study. A large carbonate quarry in the eastern U.S. was studied in detail to demonstrate the utility of PSLOPE.<br>Master of Science

Abstract:
Practices of sculpture and geography have collaborated ever since Stone Age humans hoisted up rocks to point them into the air. The ephemerality of life was rendered in a circle of forms and mass that celebrated the union of sky, earth and dwelling. Through the manipulation of stone, the land became a place, it became a home, it became situated and navigable. As millennia unfolded, the land was written with the story of itself. The creativity woven into the story of place is an evolution of material collaborations. In recent decades, academic geographers have explored the realms of creativity in their work, and sculptors have critically engaged with the nature of place. I have united these disciplines in the exploration of a truth of materials. The aim of the research was to investigate the relationship between making and place. The structure of my PhD focussed on the development of a transdisciplinary research environment that could host a range of creative practices around stone-working. I developed a long-term relationship with Trenoweth Dimension Granite Quarry, working as an apprentice sawman and mason. Here, I examined the everyday practices of labour and skill development, from which emerged deeper material and human interactions, that went on to inform my sculpture and modes of making. Arguing that granite has threads of relational agency embedded within its matrix, I initiated a series of practices that made use of my emerging knowledge as a granite-quarry worker, cast within experimental sculpture, texts, performance, photography and film. By formulating my methods around the vibrancy of matter, I disclosed new materialisms and more-than-human relations. This assemblage of documentation and artwork records and reflects on a series of practices and processes in tension. This productive tension arises from a re-rendering of artisanal practice as a research method; ushering in modes of representation as loops of experience and interpretation take place across different sites, spaces and times of mediation. The objective for the PhD research was to present a critically informed practice of sculpture-as-ethnography that could not only provide a model for practice-based research in general, but also significantly expand what might be meant by stone-work. This PhD by alternative submission is presented as a Commentary with an accompanying Digital Archive website.

Abstract:
In der Geschichte Libanons sind Steinbrüche immer für die Gewinnung von Baumaterialien wie Sand, Kies, Steine, Zement usw. genutzt worden. Durch die Komplexität dieses Sektors im Libanon gibt es kaum verfügbare Daten, Erhebungen und Studien über Ausmaß und Auswirkungen der Abbautätigkeit. Deshalb behandelt die vorliegende Untersuchung eines der drängendsten Probleme und legt eine aktuelle Datenübersicht über die Steinbrüche vor.

Meilensteine und Etappen bei der Etablierung eines Rehabilitationsprogrammes werden auf unterschiedlichen Ebenen wie der öffentliche Sektor, der private Sektor und den öffentlichen Kommunen entwickelt. Um die Nachhaltigkeit des Rehabilitationskonzeptes aufzuzeigen, wurde ein Feldexperiment in einem ehemaligen Steinbruch nördlich von Beirut angelegt. Bei dieser Rehabilitation wurden in die aufgebrachte Bodenschicht Johannisbrotbäume (Ceratonia siliqua) aufgepflanzt. Durch diese Fallstudie konnte die Nachhaltigkeit der Maßnahme für das Management natürlicher Ressourcen geprüft, unterschiedliche Ergebnisse validiert und untersucht werden.<br>Throughout Lebanon’s history, quarries have been used as a means to extract essential construction materials such as sand, aggregates, stone masonry, cement, block stone, and others. Due to complexity of the quarry sector in Lebanon very few data are available, records and studies in this field are limited. Therefore, the presented research tackles one of Lebanon’s most pressing issues and represents the most updated database on quarries in Lebanon. A comprehensive and integrated overview of the quarries issue in Lebanon in general and the problem of rehabilitation in particular are given and the problematical topic of an integrated quarry planning within a sustainable development concept in Lebanon is pointed out. Milestones and landmarks toward the adoption of a setup needed for the proper rehabilitation approach at different levels as public sector, private sector and local communities are developed. In order to demonstrate the rehabilitation concept was realised a field experiment in a closed quarry northerly from Beirut. The rehabilitation was finalised by planting of carob trees (Ceratonia siliqua) in a layer of top soil. By this case study it was possible to address a sustainable procedure for natural resources management, examine and validate.

Abstract:
An electric site project is being developed by Volvo Construction Equipment with the goal to transform the quarry and aggregate industry by reducing carbon emissions by up to 95 % and total ownership cost up to 25 %. The goal is achieved by using electrical autonomous vehicles as the work force. In an effort to reduce lead times, from design to reality, the objective of this thesis was to develop a logical architecture of a quarry using the Systems Modelling Language. The logical model contains all the essential elements existent in a quarry and describes core behavior to reflect the requirements needed in an electric site. The value of the logical model lies in its ability to aid the development process, complementing it with an executable simulation further show-cases that value. The simulation was used to analyze the performance of the electrical autonomous transporter HX02 that is instructed by an algorithm for optimal routing and scheduling. The algorithm incorporates traffic to reduce congestion at vertices with high level of activity. Its robustness is evaluated by varying the number of transporters and the weight on the traffic cost in the cost function. It was found that applying the traffic cost helped reduce the congestion significantly and increased production, but at the cost of more battery usage. The effect of incorporating traffic was most noticeable when there were more than 10 transporters operational. But when the weight on the traffic cost was too large, the production declined instead. The observed time complexity of the algorithm was O(n2), which was feasible due to a small input size n.<br>Ett elektriskt stenbrottsprojekt drivs av Volvo Construction Equip-ment med målet att omvandla hela gruvindustrin. Målet är att minska koldioxidutsläppen med upp till 95% och det totala ägarskapskostnaden upp till 25%. För att uppnå målet ska elektriska autonoma maskiner användas i stenbrotten. I syfte att minska ledtiden från design till verklighet, var målet med denna avhandling att utveckla en logisk arkitektur av stenbrottet med Systems Modelling Language. Den logiska modellen innehöll väsentliga element som återfinns i ett stenbrott och beskriver kärnbeteenden för att återspegla de krav som uppstår i ett elektriskt stenbrott. För att ytterligare påvisa värdet som den logiska modellen besitter och framföra dess betydelse i rollen att stödja utvecklingsprocessen, skapades en exekverbar simulering som ett komplement. Simuleringen användes för att analysera prestandan hos den elektriska autonoma dumpern HX02 som fick instruktioner av en algoritm för optimal ruttplanering. Algoritmen tog hänsyn till trafiken på området för att minska trafik-stockning vid noder med hög aktivitetsnivå. Dess robusthet utvärderades genom att variera på antalet dumprar och vikten på trafikkostnaden i kostnadsfunktionen. Det visade sig att introducera trafik bidrog till avsevärt minskad trafikträngsel och ökade produktionen, men på bekostnaden av en högre batteriåtgång. Trafikkostnadens påverkan var som tydligast när antalet verk-samma dumprar var högre än 10. Men när trafikkostnaden viktades för högt, minskade produktionen istället. Tidskomplexiteten hos algoritmen är O(n2) vilket är acceptabelt då mängden indata n är liten.

Although many studies about generating a safe work environment and developing safety training through intervention modules have tried to reduce the number of worker fatalities by utilizing an administrative approach to the development of safety controls, a rigorous study about understanding craftworkers' perceptions of a safe work environment is lacking. This study particularly investigated quarry workers' safety behaviors regarding work hazards by adapting findings from construction safety research because construction and mining industries have similarities in work hazards and environment. Despite their similarities, the work fatality rate in the mining industry is greater than in the construction industry (BLS, 2018). To gain a greater understanding of how quarry workers identify and interpret work hazards and employ strategies to prevent accidents, this study explored quarry workers' perceptions of work hazards (i.e., hazard identification, severity interpretation) and their preventive strategies to develop a safer working environment at the workplace. To accomplish this, a single descriptive case study was conducted with multiple sources of data such as interviews with photo elicitation, field notes, site photographs, and precursory meeting with safety managers. These sources of data were used to investigate quarry workers' identification and interpretation skills and utilization of preventive strategies. This study will contribute to improve safety of workers by incorporating workers' perceptions of work hazards and by exploring their experience to the development of safety training.<br>Master of Science<br>The surface-mining industry is one of the private industries with a high fatality rate in the United States. To reduce the number of accidents and help workers to perform safely in the workplace, previous studies have investigated different strategies to promote workers’ safety performance. These strategies include safety interventions such as safety training and safety inspections. However, a lack of study exists to understand workers’ behaviors and perceptions regarding safety and work hazards. To better explore workers’ behaviors and perceptions, this study adapted findings from construction safety research. Because the number of surface-mining safety research is relatively small and the work environment and types of work hazards in both the surface-mining and construction industries share similarities, the findings in construction safety research can be used to promote a safer workplace for surface-mine workers. By adapting findings in construction safety research, this study further investigated workers’ perceptions of work hazards, which is operationalized in two approaches: hazard identification and severity interpretation. This study also examines workers’ execution of strategies to prevent accidents. These observations were gathered through the utilization of a case study of quarry, which gave a guideline to the researcher to collect data from multiple sources (e.g., precursory meeting with safety managers, field notes, photographs, interviews) and analyze the findings by primarily using participants’ responses in the interviews with photo elicitation. This study will contribute to improve a safer workplace in the surface mining industry by incorporating workers’ perceptions and experience and by emphasizing workers’ involvement in tandem with company commitment to develop safety training.

Abstract:
This thesis presents a study of the characterisation of fine aggregates manufactured from waste quarry material and their use in concrete supported by artificial neural network models of the fresh and hardened concrete properties. The reutilization of rock filler, a by-product of the sand manufacturing process, as a soil liming material is explored. A set of tests and techniques were identified to characterise fine aggregates manufactured from quarry dusts via a dry processing system. Granite, limestone, sandstone and basalt manufactured sands and their unprocessed counterparts “feed quarry dusts” were characterised with respect to their shape and texture, grading and quality of fines (presence of clays). The results showed that the reprocessing of quarry dusts improves the particle shape and grading irrespective of rock mineralogy. Plasticised and non-plasticised concrete mixes were developed and the fresh and hardened properties tested. Concrete consistency, compressive and flexural strength is correlated with the fine aggregate characterisation test results. The manufactured fine aggregates showed a higher water demand when compared with natural sand whereas compressive and flexural strengths were enhanced. Artificial neural network models were developed to enable the prediction of the consistency and compressive strength of concrete. These models used the fine aggregate properties and mix composition parameters as input variables and were validated using a separate testing dataset, additional concrete mixes and numerical evaluation. Artificial neural network models were shown to be able to predict fresh and hardened concrete properties based on the fine aggregate characteristics. The excess fillers created in the sand manufacturing process were evaluated for soil liming potential through standard tests and a soil incubation study. The main finding was that materials with high silicate content exhibit a potential for liming, however, a higher dosage is required when compared to the dosage of high purity limestone to achieve the same liming potential.

Abstract:
<p>Determination of the subsurface geology is very important for the rock quarry industry. This is primarily done by drilling and mapping of the surface geology. However in Sweden the bedrock is often completely covered by Quaternary sediments making the prediction of subsurface geology quite difficult. Incorrect prediction of the rock-mass quality can lead to economic problems for the quarry. By performing geophysical measurements a more complete understanding of the subsurface geology can be determined. This study shows that by doing 2D-parallel data sampling a 3D inversion of the dataset is possible, which greatly enhances the visualization of the subsurface. Furthermore the electrical resistivity technique together with the induced polarization method proved to be very efficient in detecting fracture frequency, identification of major fracture zones, and variations in rock-mass quality all of which can affect the aggregate quality. With this technique not only the rock-mass quality is determined but also the thickness of the overburden. Implementation of geophysics can be a valuable tool for the quarry industry, resulting in substantial economic benefits.  </p>

Abstract:
Ecological restoration allows for accelerated recovery of a degraded ecosystem’s biodiversity, function, and ability to provide ecosystem services. However, the issues of when active restoration is necessary and how restoration effectiveness should be measured are still subject to considerable debate. Here we evaluate plant-pollinator networks in actively and passively restored quarries, comparing structure and composition to a natural area representing the reference ecosystem, to determine which restoration approach holds higher effectiveness on the rehabilitation of this ecological process. We found that while both approaches allowed for the restoration of pollination function, active restoration allowed for faster recovery. Nevertheless, the distinct strategies generated key structural vegetation differences, which influenced distinct pollinator communities providing the service in different areas. These results support the idea that restoration might be attained by distinct biological communities, and that both composition and function should be taken into account when evaluating restoration outcomes; RESUMO: O restauro ecológico permite acelerar a recuperação da biodiversidade, função e serviços de um ecossistema degradado. No entanto, existe bastante debate sobre as situações em que é realmente necessário o restauro ativo e como deve ser avaliado. Neste estudo, avaliamos redes plantapolinizador em pedreiras restauradas ativamente e passivamente, comparando a sua estrutura e composição com uma área natural que representa o ecossistema de referência, para determinar a abordagem mais eficiente na reabilitação da polinização. Verificámos que, apesar de ambas permitirem o restauro desta função, o restauro ativo permite uma recuperação mais rápida. No entanto, estratégias distintas geraram diferenças estruturais na vegetação, o que influenciou o estabelecimento de comunidades de polinizadores distintas a polinizar as diferentes áreas. Estes resultados apoiam a ideia de que o restauro pode ser atingido com comunidades biológicas distintas, e que a composição e a função devem ambas ser tidas em conta na avaliação do restauro ecológico.

Abstract:
Whitehall Quarry is located 4 km east of Karapiro, near Cambridge within the Waikato District. Current quarrying operations produce between 150,000 and 300,000 tonnes of aggregate for use in the surrounding region. This study is an investigation into the engineering geological model for the quarry and pit slope stability assessment. Pit slope stability is an integral aspect of quarrying and open-pit mining since slopes should be as steep as possible to minimise waste material which needs to be removed, yet shallow enough to minimise potential hazards to personnel and equipment below pit slopes. This study also assesses the stability of complex wedge located within the north western corner of the quarry. Initial estimates approximate a wedge mass volume of 500,000 m3; failure was triggered during the late 80‟s due a stripping programme at the head of the mass. Field and laboratory investigations were carried out to identify and quantify engineering geological parameters. Photogrammetric and conventional scanline analytical techniques identified two domains within the quarry divided by the Main Quarry Shear Zone (MQSZ). Discontinuity orientations are the key differences between the two domains. Bedding planes appear to have slightly different orientations and each domain has very different joint sets identified. Point load, shear box, ring shear testing approximated intact rock strength, shear strength and fault gouge behaviour properties. The main geological units at the quarry are greywacke sandstone interbedded with argillaceous mudstone. Uniaxial compressive strength estimates approximated the intact rock strength for sandstone to be between 30 and 230 MPa depending on weathering grade, while the strength of mudstone was approximated at 5 MPa. Residual shear strength was carried out to estimate the approximate effective angle of internal friction for both a smooth UW-SW sandstone joint and a mudstone bedding plane, these being 37o and 34o respectively. Laboratory testing on fault gouge indicated an approximate angle of internal friction of 13o and the presence of kaolinte and montmorillonite was identified. Pit slope stability analysis utilised the Markland test for identification of potential failures within slopes. Wedge failures are the most common potential failure type, then planar failures along bedding planes. Potential failures are most likely to be less than 10 m3 due to the high fracture frequency and low persistence of common joint sets. However, larger failures in the order of 100 m3 are possible along fault and bedding planes where persistence is typically greater than 20 m. Kinematic analysis of the Northern Wedge Failure estimated a mean factor of safety of 0.97. Currently the wedge is assessed as marginally unstable. Electronic distance measurement over 11 months recorded an approximate mean wedge velocity of 19 mm/month. Sensitivity analysis identified pore water pressure as a key parameter. De-watering the wedge via a series of inclined drainage holes appears to be the best mitigation method. However, the mine and monitor approach is also acceptable but with anticipated risk to personnel and equipment. Monitoring instrumentation such as a wireline and crack-meters should be implemented.

Abstract:
The purpose of this creative project was to derive and communicate the design process for the reclamation of an active quarry site to a residential community. An examination of existing land reclamation and housing design knowledge was conducted to form the basis for original design theories. The communication and presentation of study recommendations was applied to a case study site: an active sand, gravel, and limestone quarry located near Muncie, Indiana. A methodology was developed to analyze the site for its mining, housing and visual potential. Environmentally responsive strategies to determine rural community structure, lake form design, and housing character were developed. An integration of analyses and design strategies yielded the final land use concept and the associated site development concept. The final product of the study was a reclamation concept plan directing mineral extraction and reclamation efforts toward optimal mining and housing potential. It was the intention of this study to discuss and present its design theories, recommendations, and process in map form capable of explaining the study in its entirety without additional verbal or written communication.<br>Department of Landscape Architecture

Abstract:
The research presented in this thesis results from efforts to evaluate current design methodologies for safety benches in surface aggregate quarries. Proper bench design is important for preventing rockfall related accidents and injuries without wasting the reserves held in the benches. An in depth analysis has been performed using the results from 230 rockfall tests conducted at two surface quarries. The goal of this project is to give practitioners the tools they need for improved bench design. Principal Components and Cluster Analysis, techniques not previously applied to rockfall investigations, have been performed on the test data. The results indicate that both are valid analytical methods which show that the factors affecting the rollout distance of a rock are wall configuration, rock dimensions, and rock energy. The test results were then compared to the Ritchie Criteria, Modified Ritchie Criterion, Ryan and Pryor Criterion, Oregon Department of Transportation design charts, and RocFall computer simulations. Analysis shows that the lognormal distribution curves fitted to the test data provide an excellent yet quick design reference. The recommended design method is computer simulation using RocFall because of the ease of simulation and the site specific nature of the program. For the two quarries studied, RocFall analysis showed that 20 ft benches with a 4 ft berm will hold over 95% of rockfalls, a design supported by the field testing. Conducting site-specific rockfall testing is also recommended to obtain realistic input parameters for the simulations and to provide design justification to regulatory agencies.<br>Master of Science

Abstract:
This thesis explores relationships between the National Mall and the quarries that supported its construction. It focuses on the Washington Monument and its source of material, the Cockeysville Quarry, Maryland. By studying the movement of stone, the thesis begins to understand both sites as landscapes in process. It then examines the sites histories including land forms, immigrated laborers and railways changes associated with quarrying and construction. It happens that Ian McHarg also studied both sites fifty years ago in Design with Nature. Mcharg's analysis overlooks the potential of the industrial quarry to recharge the Marble Valley aquifer and does not account for the projected sea level rise on the National Mall. It is necessary to examine the two sites again. McHarg's ecological principles and methods are still the basic evaluation criteria for the examination (especially his understanding of landscapes as process.) The design project of this thesis uses shifting hydrologies at both sites to drive new uses,earthwork, urban forest (tree canopies), and axial relationships, inspired by the materials, forms, and historical links between the two landscapes. By looking at the landscapes as a pair, the design recalls the past connections between the sites and constructs new relationships ideologically and physically.<br>MLA<br>It is common for there to be a separation between quarries and the buildings and landscape we create from their materials. People rarely realize the materials are the records and links of the history, culture, society and ecology of the paired landscape between construction and material producer. This thesis starts from investigating the origin of building stones used for the memorials on the National Mall. Tracing stone sources links the National Mall landscape and the quarries that supported its construction. It focuses on the Washington Monument and its source of material, the Cockeysville Quarry, Maryland. The thesis examines the geographic, hydrological and physiographic information of the landscape between the National Mall and the Cockeysville Quarry based on ecological methods, especially the understanding of both sites as landscapes in process. It also studies the sites’ histories including landforms, immigrated laborers, and railways changes associated with quarrying and construction. The thesis design project explores the question of how the relationships can be reflected and applied in the intervention of the two landscapes. Within the framework generated by the relationship study, water issues have been identified as the main common problem. Protecting the Marble Valley aquifer and dealing with the thread of the sea level rise on the National Mall is the major consideration. The main strategy of design is to use the anticipated hydrologies to drive the new uses, earthwork, urban forest (tree canopies) at both sites. The second strategy of design is to use history, form and material relationships to inspire new connections between the sites ideologically and physically.

Abstract:
This study presents the dewatering assessment of a marl quarry with the future pit lake level predictions. The objectives of the study were<br>(1) to determine the dewatering requirements that would allow for the continuation of the quarrying operations in the deeper parts of the quarry, (2) to design an optimum dewatering system compatible with the site hydrogeological conditions and quarrying plans, (3) to assess the environmental impacts of dewatering on the local water (surface and ground water) resources and users, and (4) to predict the future pit lake level and flooding period for different meteorological conditions. To these ends, previous investigation reports and maps have been compiled and reviewed and field investigations have been conducted. During the field investigations pumping and observation wells were drilled and installed. After installation, in situ tests were conducted to determine aquifer parameters. It was found that properties of the material is conducive to the dewatering activities that will be necessary for the deepening of the open pit of the marl quarry. A groundwater model was developed based on the field data gathered. According to this model dewatering trenches will be needed to dewater the pit. The model predicted that operating these dewatering trenches would create an elongated cone of depression that will sufficiently lower the groundwater table so that quarrying operations can proceed. Lowering of the water table may produce a negative impact on groundwater resources within the aerial extent of the cone of depression. This potentially negative impact was investigated with model simulations and has been found that the impact to the resources would be negligible. Three scenarios were evaluated as possible dewatering discharge disposal solutions. The preferred scenario included the discharge of this water to the stream, which is flowing on the western side of the quarry. The pit will start to fill with water immediately after the dewatering operations stopped. In order to predict the pit lake flooding period and final lake elevation, pit lake hydrologic model was developed. The simulations predict that the final pit lake elevation would be at 991 m. The pit lake will rise to this level at approximately 72 years after closure.

Full text
Abstract:
Until recently, there were two types of man-made rock slopes: civil engineering and mining / quarrying related. The factors differentiating these two slope types are relative life span, safety requirements and construction cost. For civil engineering slopes, these requirements are high, whereas for mining slopes they are usually lower. The tightening of UK/EU environmental legislation has created a third category of rock slope: the quarry faces produced by or remaining after the end of the extraction operation in Areas of Outstanding Natural Beauty and National Parks. Such slopes have life spans and safety requirements similar to civil engineering slopes but with the construction cost of mining and quarrying slopes. Due to the fact that a considerable amount of time may elapse between the end of the extraction operation and a quarry's potential or intended after-use, quarry operators want to know what will happen to the faces if they remain free of conventional support methods. Consequently, the aim of this project is to asses the impact of weathering agents on the stability of different types of Carboniferous Limestone quarry faces in the Peak District National Park, UK. Two methodologies were followed. These comprised: firstly, in situ monitoring of the stability of selected quarry slopes and secondly, accelerated weathering tests on rock samples collected from the monitored slopes, and measurement of some of their mechanical and physical properties. Only cost-effective techniques that could be readily employed by the quarry industry were used. From comparison of the resultant data, the main conclusion is that, in contrast to the findings of published research into the rate of weathering of rock materials, Carboniferous Limestone rock faces at the sites studied do not display a linear decline in their mechanical and physical properties due to weathering processes. Rather, they either display no significant alteration or an alteration following a concave trend, with an initial decline and subsequent increase in their properties. This means that their stability does not deteriorate at a constant rate over time. The implications of this for the selection of appropriate restoration methods are discussed and some alternative strategies are proposed.

Abstract:
Bibliography: leaves 86-92.<br>Quarry operations are only a temporary use of the land, while the environmental impacts associated with them are more long term. For this reason, it is unacceptable to merely abandon a quarry once operations have ceased. This study considers the role of rehabilitation in providing solutions for the disturbances caused by quarrying. The value of adopting a pre-planning approach towards rehabilitation is considered, and the components of a rehabilitation programme are identified. Using this information a rehabilitation checklist is drawn up. A survey of thirty rehabilitation reports, submitted to the Cape Town regional offices of the Department of Mineral and Energy Affairs, was undertaken using the checklist. Results of this survey indicate that rehabilitation reports are submitted merely to meet the minimum legal requirements contained in the Minerals Act of 1991 (Act No 50 of 1991). This study recommends that successful rehabilitation will only be achieved when rehabilitation reports function as effective working documents.

Abstract:
This dissertation departs with an enduring interest in the social Milieu and the future projections of the fringes of South African major cities, specifically Cape Town, as urbanization broadens, transforms and makes the edge more complex. This document analyses this phenomenon in Dunoon Township and presents a case for vertical allotment farming in this context. The research, looks at this phenomenon as a narrative of land ownership in its most physical depictions, such as the story of the ownership of land to reap resources as the physical phenomenon of an abandoned quarry. This project acknowledges the danger and light treading around contentious environments, such as townships, which seem to create architecture that aggravates protest and vandalism, but chooses to counteract the pervasive 'headline-ing' of these areas by showing a township, Dunoon, as quotidian. This document does this by engaging with the life around the edge of the oldest quarry in the Durbanville Hills area - Once a source of great benefit and value to its immediate environment - now a fenced off cesspit for crime and superstition. An empathetic attitude towards considering material developed within the immediate environment to create value, as opposed to sourcing it from outside, is a founding precept for the design endeavour. The project can be described as a process which began by understanding the stagnant water within the basin of the quarry, what systems already exist to bring value to the urban fabric, and how the water can be best used in its mundane life. Beauty, viewed through the lens of this document, is something that brings undeniable usefulness to an area. That is the intervention of a wasted public space with rancid polluted water into clean usable water for a community suffering crippling rates of water shortage and cut-offs. It aims to put permaculture ideals into use by routing the stagnant water and making it into a system that consistently cleans itself over time. Routed water embeds a logic that becomes the catalyst for the fulfilment of a bio-inspired future -of which I emphatically advocate. This dissertation seeks to create an intervention which should encourage a new relationship with water in Dunoon. It is through a gathering of found program; farmers, NGO facilitators, walkers, joggers without tracks, children without playgrounds, women without laundry water tipping points, that the community is brought together in the water world of Dunoon quarry.
