Abstract:
Rock mechanics test is not only the basis for obtaining the mechanical parameters of rock but also an important means for studying rock mechanics and engineering. In this paper, the uniaxial compression deformation test, Brazilian splitting test, and cornea pressure shear test are carried out for rocks in the Dajishan tungsten mine. The basic mechanical parameters such as uniaxial compressive strength, tensile strength, elastic modulus, Poisson’s ratio, and internal friction angle of ore rock and surrounding rock are obtained. Meanwhile, damage characteristics of rock are deeply studied and analyzed under different experimental conditions. According to rock mechanics parameters which are obtained from indoor rock mechanics tests, three design schemes of stope structure parameters are optimized by using the FLAC3D numerical simulation software. On the premise of ensuring the stability of the stope structure, the recovery rate of ore and the production capacity of the stope are taken into consideration. It is suggested that the second scheme should be adopted for mines (18 m for ore room and 7 m for ore pillar), which provides scientific guidance for the safe and efficient mining of mines.

Abstract:
Sedimentary rocks with layered structure account for two third of global land area, and this proportion is 77.3% in China, lots of metamorphic rocks also have significant features of layered structure, so there are a large number of stability problems about layered rock mass in mining engineering. Layered rock mass is generally considered to be transversely isotropic solid in mechanics. Based on the complex variable expression of displacement components of transversely isotropy, the displacement analytical solution of a deep elliptical tunnel in transversely isotropic rock mass is derived by conformal mapping method.

Abstract:
To increase understanding of the strength and failure mechanism of rocks with arch-like fractures generated in the overlying strata above a gob during coal mining, a series of uniaxial compression tests on rock-like specimens containing two preexisting parallelogram flaws at inclination angles varying from 45° to 75° were made using a rock mechanics servocontrolled testing system. Based on the experimental results, the effects of the inclination angles of two flaws having the same area on the mechanical parameters and fracturing process of the specimens were analyzed in detail. By adopting photographic monitoring, the crack initiation, propagation, coalescence, and failure modes in rock-like specimens were observed and characterized. The crack initiation stress and the second initiation stress were distinctly related to the flaw inclination angles, although the crack initiation stress presented a change trend generally similar to that of the crack second initiation stress with increasing flaw angle. Four modes of ultimate macroscopic failure morphology and the crack coalescence and failure modes of three types could be summarized. The research reported here could provide some theoretical support for the arch-like fracture evolution in the overburden during the excavation in underground engineering, especially in coal mining engineering.

Full text
Abstract:
Since blasting is a comminution process, the feasibility of establishing a correlation between the Bond rod mill work index (kWh/t) and some easily measurable physico-mechanical properties relevant to blasting was investigated. Further, the concept of operating blast work index and its potential applications were explored. Four different rock types and a well documented case study of two blasts were selected for this study.
The work index is found to be uncorrelated with the density and unconfined compressive strength, slightly related with tensile strength, and well correlated with dynamic rock properties, especially the P-wave velocity and the bulk modulus. The standard deviation in measured compressive and tensile strength values is found to be very high, compared to their seismic and dynamic elastic properties.
The case study encompassed two blasts with identical blast-patterns and rock type consuming almost the same amount of explosive (kg/t) but with very different specific blast energies (MJ/t). The agreement between operating work index of the two blasts (13.4 kWh/t vs. 13.1 kWh/t) and laboratory work index (17.0 kWh/t) was modest (within 30%). The operating work index corresponding to either blast has been used to predict the product size (P$ sb{80}$) of the other. The choice of feed size (F$ sb{80}$) was discussed; whereas the previous researchers had used the theoretical value of infinity, the use of much smaller value, the average of effective burden and spacing, was proposed. This concept is used in a proposed method to estimate blasting energy requirements as a function of blast geometry, rock type and desired product size. Future test work that would provide a data base and validation for this concept is described.

Full text
Abstract:

Case histories in mining have long described pillars or faces of rock failing violently with an accompanying rapid ejection of debris and broken material into the working areas of the mine. These unstable failures have resulted in large losses of life and collapses of entire mine panels. Modern mining operations take significant steps to reduce the likelihood of unstable failure, however eliminating their occurrence is difficult in practice. Researchers over several decades have supplemented studies of unstable failures through the application of various numerical methods. The direction of the current research is to extend these methods and to develop improved numerical tools with which to study unstable failures in underground mining layouts.

An extensive study is first conducted on the expression of unstable failure in discrete element and finite difference methods. Simulated uniaxial compressive strength tests are run on brittle rock specimens. Stable or unstable loading conditions are applied onto the brittle specimens by a pair of elastic platens with ranging stiffnesses. Determinations of instability are established through stress and strain histories taken for the specimen and the system.

Additional numerical tools are then developed for the finite difference method to analyze unstable failure in larger mine models. Instability identifiers are established for assessing the locations and relative magnitudes of unstable failure through measures of rapid dynamic motion. An energy balance is developed which calculates the excess energy released as a result of unstable equilibria in rock systems. These tools are validated through uniaxial and triaxial compressive strength tests and are extended to models of coal pillars and a simplified mining layout.

The results of the finite difference simulations reveal that the instability identifiers and excess energy calculations provide a generalized methodology for assessing unstable failures within potentially complex mine models. These combined numerical tools may be applied in future studies to design primary and secondary supports in bump-prone conditions, evaluate retreat mining cut sequences, asses pillar de-stressing techniques, or perform backanalyses on unstable failures in select mining layouts.

Full text
Abstract:
Rockbursts may cause damages to underground openings and to equipment, and constitute a major hazard to the safety of mine workers. One method that can be used to evaluate if there is a rockburst potential is to compare the stiffness of the failed rock with that of the surrounding rock mass. This method has been applied successfully in the past to rockbursts involving fracturing of the rock mass.
This thesis deals with the development of a similar approach for rockbursts involving a violent slip along major geological discontinuities. To evaluate the post-peak shear stiffness of a discontinuity, a new non-linear constitutive model for rock joint was developed. This model is based on two exponential formulations expressing the two phenomena taking part in the shearing process: friction resistance along surfaces and shearing of asperities. Compared with test results, the model showed a correlation factor (R2) of 0.90. The model was then implemented in an existing boundary element code to evaluate the interaction between underground openings and nearby geological discontinuities. Verification of the implementation was done by reproducing direct shear tests on a discontinuity. Parametric analyses were performed on the new model that highlighted the most important parameters. Methods to obtain the different stiffnesses involved in the violent slip process were developed. Examples of applications were given to illustrate the proposed methods.
Finally, an alternative method to evaluate the fault-slip rockburst potential was developed. This new method relies on a linear analysis and the calculation of a new index called the Out-of-Balance Index or OBI. The OBI showed some agreement with the stiffness approach.

Abstract:
As humanity prepares to migrate to the frontiers of the Moon and other planets, the area of mining in space must go along for the purpose of exploration and in-situ resource utilization. In the present work the literature that has been developed over the years in the area of mining in space as applicable to Lunar and Martian environments is reviewed. Subsequently, the key mining technologies that are most suitable for Lunar and Martian environments are identified. From the literature review, it is concluded that an optimal combination of both mechanical methods and novel energy (lasers, microwaves, nuclear energy) methods for rock destruction drawing a trade off between the energy and mass would be the most ideal option for space applications.
One such technique of applying low power microwaves to the rocks to thermally weaken them without actually melting them before employing mechanical methods of rock destruction is investigated. Finite element simulations were carried out to simulate microwave heating of a calcareous rock to determine the temperature profiles and thermal stresses at different microwave heating times and powers. Preliminary experiments were carried out in order to determine the microwave susceptibility of terrestrial basalt (which has similar composition as Lunar and Martian rocks). Temperature and strength of the rock sample before and after microwaving was measured.
The results of the finite element simulation indicated that a calcareous rock with microwave responsive phase and a microwave non-responsive phase developed thermal stresses of large magnitudes exceeding the actual strength of the rock. The simulation methodology can be applied to other rock types as well, provided the thermal, electrical and structural properties of constituent mineral phases are available.
The preliminary experimental results showed that the basalt rock specimens used were quite susceptible to the low power microwaves. There was a decreasing trend in terms of the point load index of the rock samples as the microwaving exposure times were increased, with some rock samples showing visible cracks at higher microwaving times.

Abstract:
Wheel loaders are widely used in mines, construction projects, and waste processing fields due to their merits of high mobility, remarkable operational flexibility, and relative low capital cost. Automatic control of the loading process will achieve high productivity, solve the problem of shortage of experienced operators, release human workers from hazardous working environments, and reduce maintenance cost associated with machine abuse. Existing research on wheel loader control only automate the manipulator mechanism while leave the locomotion system to human operators. The research in this dissertation focuses on the development of a digging controller that can simultaneously control bucket motion and vehicle advancement, and can adapt its parameters in different digging conditions. In this controller, a digging task is decomposed into three sequentially implemented operations: attacking, crowding, and scooping; each of them can be carried out with different strategies. An ideal trajectory is pre-generated based on the physical property of the wheel loader and rock pile, and is generally followed during the digging process. Human operators' practice in regulating vehicle speed and coordinating bucket motion and vehicle advancement is intensively investigated, refined into control rules, and implemented with intelligent and conventional control methods. Machine features are analyzed in depth and incorporated into control algorithm design. The investigation on the non-trivial time-delay characteristic of the manipulator hydraulic system leads to the building of dynamic models and the application of predictive control principle in digging decision-making. The feature of small working space of wheel loader was considered in bucket trajectory generation and instant bucket motion planning. The research on wheel slip occurrence leads to a detection algorithm being developed and a slip restrain strategy being presented. Self-adaptation mechanism is constructed in which trajectory tracking-quality is applied for evaluating digging control performance, statistical analysis is applied for improving the accuracy on bucket penetration depth prediction, and machine-learning technique is applied for revising the membership function of fuzzy consequent variables. Simulation experiments show that the controller works effectively in rock piles with different conditions, from fine sand and soil to big fragmented rock pieces.

Abstract:
Assessing long-term rock stability is an important aspect in the analysis of slopes, dam and bridge foundations, and other infrastructure. Rock behavior over tens to thousands of years must be anticipated when predicting the performance of, for example, an underground containment facility for nuclear waste. At such long time scales, the time dependence of rock failure, typically ignored in short time scale analyses, has a significant effect and must be included in the analysis. Since time-dependent rock behavior is thought to be caused by the subcritical growth of microcracks, a time-dependent analysis should incorporate a method of simulating subcritical crack growth. In this thesis, a rock bridge damage model was developed using the finite element program Abaqus to simulate subcritical crack growth for all three modes of crack tip displacement in three-dimensional rock masses. Since subcritical crack growth is not among the damage initiation and evolution criteria available in Abaqus, its effect was included in the model through the USDFLD user subroutine. Material properties for the damage model were obtained through laboratory fracture toughness testing of Escabrosa limestone from Kartchner Caverns. Tests included the grooved disk test for mode I, the punch-through shear with confining pressure test for mode II, and the circumferentially-notched cylindrical specimen test for mode III. The subcritical crack growth parameters n and A were calculated for all three modes using the constant stress-rate method. Fracture test results were compared with a previous study by Tae Young Ko at the University of Arizona, which tested Coconino sandstone and determined that the subcritical crack growth parameters were consistent among modes. This thesis expands upon Ko's work by adding the characterization of a second rock material in all three modes; results indicate that for Escabrosa limestone the subcritical crack growth parameters are not consistent among modes. Additionally, the Escabrosa limestone composing the caverns ranges from a more homogeneous, even-grained texture to a more heterogeneous texture consisting of coarse-grained veins and solution cavities set in a fine-grained matrix. To determine if the veined regions are more susceptible to fracturing and act as the nuclei of rock bridge failure, the fracture toughness tests were conducted separately for each texture. Results indicate that the more heterogeneous limestone has a higher fracture strength, fracture toughness, and subcritical crack growth index n than the more homogeneous limestone. This is in agreement with previous studies that determined that a more complex and heterogeneous microstructure produces a larger microcrack process zone and a more tortuous crack path, leading to higher fracture energies and larger values of n. Application of the rock bridge damage model to a simplified Kartchner cave room with a single roof block provided visualization of decreasing rock bridge size and produced time-to-failure estimates of 1,251 to 65,850 years. Multiple models were run to study the effect of (i) using material properties from each of the two textures identified in the Escabrosa limestone and (ii) varying the in-situ stress ratio, K. Both the value of K and the choice of Escabrosa texture had a large effect on the estimated time-to-failure, indicating that for future modeling of Kartchner accurate estimation of the in-situ stress ratio is as important as field identification of homogeneous vs. heterogeneous textures.

Mahony, Luke T. School of Mining UNSW. "Development of a laboratory facility for testing shear performance of installed rock reinforcement elements." Awarded by:University of New South Wales. School of Mining, 2006. http://handle.unsw.edu.au/1959.4/25700.

Full text
Abstract:
Rock reinforcing elements provide a significant proportion of their ground control capability through offering resistance to shear movement of adjacent rock masses or blocks. This potential shear movement may take the form of sliding on horizontal bedding planes leading to strata bending; or block displacement along other geological structures such as joints or similar discontinuities. Much has been reported about this type of behaviour of rock bolts and other tendons, in theoretical concepts. However, there is a shortage of quality data available on the exact nature of this mechanism for shear resistance, and the role played by parameters such as pre-tensioning. A clearer understanding of the nature and significance of this type of behaviour has major implications for rock reinforcing materials and installation design. This thesis, which was supported by the Australian Coal Research Program (ACARP) describes the design, construction and commissioning of a laboratory testing facility at the School of Mining Engineering, University of New South Wales (UNSW), Australia and a subsequent testing program. The single failure plane design adopted in the test rig has been successful in allowing shear loading to be directly applied to fully installed rockbolts. Rockbolts were installed into an offset concrete rockmass, which consisted of two separate concrete samples that created a smooth shear plane surface. The reinforced samples were subjected to an applied shear load and critical parameters such as load and shear displacement were recorded. Influencing parameters such as concrete strength and applied pre-tension were altered and recorded to determine their effects on the overall shear performance of the sample. The failure mode of the rockbolts was also examined. The results indicate that a relative stronger rockmass material caused the rockbolt to fail within a lower shear displacement compared to a relatively weaker material. Also, a pre-tensioned rockbolt tended to resist shear displacement at least initially, until high shear loads developed. This phenomena is beneficial to ground support as less movement would tend to maintain integral strength of the rockmass. The use of strain-gauged rockbolts indicated as would be expected that the shear loading arrangement induced a compressive axial loading that tended to dissipate with distance from the shear surface.

Abstract:
Earthmoving is a common activity at mines, construction sites, hazardous waste cleanup locations, and road works. Expensive and sophisticated machines such as front-end-loaders (FEL), backhoe loaders, LHD loaders and front shovels are used for these excavation tasks. Autonomous excavation control for these machines has gained considerable attention in order to remove human operators from hazardous environments, improve productivity and utilization, reduce machine abuse, as well as decrease machine operating costs. However, automatic control of excavation tasks for many sites that require digging in rock cannot be implemented using existing factory-based automation techniques. For example, control of bucket motions by simply partitioning the terrain into a set of volumes where each equals the bucket capacity often does not work. Planning in this way is possible only when digging in the materials such as loose soils where bucket motion resistance through the media can be predicted. Resistance predictions are impossible and/or infeasible to generate for excavation in the environments which consists mainly of irregular rigid objects such as rock piles with oversized particles, since no means exists to predetermine subsurface bucket/material interactions that are required to preplan the bucket trajectory. As a result, bucket actions must be determined through on-line decision making based on sensory feedback of the current excavation status in the unpredictable, unstructured and dynamic rock excavation environment. This research proposes a control method for autonomous rock excavation. The control architecture is designed following the behavior-based control concept. That is, the rock excavation control problem is solved by decomposition of the complicated task into a variety of simple elements that can be implemented by excavation behaviors. However, this control approach presents a new structure and operational paradigm that is developed based on, but different from the traditional behavior control method. Here, the behaviors are chosen using fuzzy excavation situation assessment with guidance of excavation task planning which embodies excavation heuristics and human strategies. Task plans are formulated using finite state machines which integrate neural networks for decision making. This organizational structure has the capability to include more excavation goals and to adapt to different environments via learning. Excavation behaviors are performed by primitive and machine executable actions or action sequences structured using finite state machines and simple action arbitration rules. The actions of human FEL operators were observed and analyzed to extract basic bucket actions and define rules of arbitration for different actions or action sequences under particular excavation environments. Fuzzy logic is applied to implement each excavation action where fuzzy rules represent the human experience and heuristics that are intrinsically linguistic, and bucket excavation motions are evaluated based on insufficient and inaccurate input sensory data. A variety of experiments were performed to test the ability of the proposed control algorithm. The laboratory-based experimental autonomous excavation system consists of a robotic arm, an excavation testbed, a force/torque sensor mounted between the robot arm wrist and the excavation bucket, and a control computer. Various rock piles to simulate realistic excavation environments and conditions were generated in the testbed. With these experiments, the control algorithm has demonstrated the ability to execute real-time automated loading cycles effectively and efficiently in complex excavation environments and under difficult digging conditions, through the use of the flexible excavation behaviors.

Abstract:
In deep sea mining processes, rock is being cut in a hyperbaric pressure environment. The effect of such a high pressure environment is of major influence on the cutting process. Due to deformation of the rock matrix, local fluid pressure differences will occur. This can result in a higher apparent strength of the rock, but also in a higher (loading) rate dependency. Our new modeling approach aims at combining both rock mechanics and fluid dynamics to model the high deformation (rate) behavior experienced in seabed excavations. This new approach is based on the Discrete Element Method to simulate the rock mechanics, combined with the use of Smoothed Particle Methods to model the influence of the fluid (pressure) on and in the rock. In this paper, emphasis is put on estimating the local (volumetric) deformation rate with the new approach. Eventually, the new technique will be validated with experiments and data available in literature. The new approach will give more insight in the physical processes that occur during cutting.

Abstract:
Steel roller discs are an efficient mechanical tool for cutting soft to medium strength rocks in both civil and mining projects. However, their application for hard rock cutting has been hindered since steel discs wear quickly and fail prematurely due to high concentrated stresses generated at the sharp corners and thin elements of the disc. To overcome this problem, the current generation roller discs comprises a steel shaft connected to a tungsten carbide (WC) disc. In other words, while the material of the disc itself is replaced by a stronger WC material, steel continues to be used for the shaft body. In this paper, to comprehend the influence of material parameters on the induced stresses inside different parts of a roller cutter, an analytical closed-form solution and a series of finite element (FEM) numerical studies are performed. By considering the problem as a traction boundary-value problem in an elastic domain, the analytical solution is based on the Airy stress formulation in Cartesian coordinates with a Fourier series representing the boundary conditions. The analytical result is developed for both plane stress and plane strain conditions, encompassing all possible loading configurations and shaft geometries. To verify the numerical models, these results are also compared with laboratory experimental data obtained from cutting granite using mini discs for the penetration range 1 to 3 mm.

Abstract:
Mechanical rock cutting is a process encountered in different engineering applications including rock excavation, mining and deep oil well drilling. Rock mechanical properties vary with depth in the subsurface and also at different geographical locations due to different environmental conditions. Understanding of fragmentation mechanisms in specific rock materials allows the determination of optimum cutting parameters that improve cutting efficiency and increase tool life during cutting operations. In the present investigation, numerical models that accurately predict the rock fragmentation and stress profiles in the rock slab during cutting were developed using the explicit finite-element method (FEM). In the numerical models, a damage material model was utilized to capture the rock fragmentation process and a rigid steel cutter (at different rake angles) was displaced at different velocities against a stationary rock slab. Rock slabs with significantly different mechanical properties were incorporated with a constant friction factor and a cutting depth of 1 mm. The variation of cutting forces and stresses, and fragmentation of the rock slab were analyzed. The simulation results indicated that the explicit FEM is a powerful tool for simulating rock cutting as the formation of fragments were distinctly observed at different cutting conditions. The rock mechanical properties and tool rake angle were found to have the most significant effect on the rock fragmentation during cutting operations. The cutting forces were also influenced by mechanical properties of the rock and tool rake angle.

Abstract:
Preconditioning of hard rocks by microwave energy has recently been considered a potentially effective technology in mechanical rock breakage for civil and mining engineering. To obtain the amount of mechanical damage that a single-mode microwave treatment produces in rocks, it is necessary to analyze and evaluate the thermal cracking process by microwave heating at different power levels, exposure times, and distances from the antenna. The current study employs the scanning electron microscopy imaging technique to capture images from surfaces of irradiated rock specimens and to compare them with a nontreated specimen. To evaluate and quantify the amount of cracking (i.e. crack density, crack size, etc.) in a rock specimen after microwave irradiation with different microwave input operating parameters, the following steps were evaluated. First, several experiments of single-mode microwave treatments with different operating parameters were performed on rectangular specimens of basalt. Then, cylindrical core samples with a dimension of r = 0.5 cm, h = 2cm, were drilled from the center of the irradiated specimens and prepared for image processing. The results of the present study show that there are significant differences between the number of microcracks present in samples irradiated at different power levels and distances from the antenna. Also, longer exposure times result in more severe cracks.
