Abstract:

Illegal sand mining is carried out causing bad environmental problems. There needs to be a solution to solve the problem of illegal sand mining. The purpose of this study is to describe the impact of illegal sand mining in Merauke and the role of local wisdom to prevent illegal mining. This research is descriptive qualitative research. The place of research is Ndalir beach, the beach where sand mining occurs, and also Tomer village as one of the villages affected by illegal sand mining. Data was collected by direct observation and also in-depth interviews with several communities. The data obtained is that illegal sand mining provides benefits to the customary landowners of the sand village and also provides income to the sand miners. The negative impact of illegal mining is that it causes damage to mangrove forests resulting in abrasion, rising seawater to roads and homes, damage to roads and bridges. The solution is to adopt the local wisdom of the Kanum tribe, to prevent illegal sand mining.

Abstract:

Beach sand mining caused externalities. Externalities are negative impact caused extraction excessive. Road damage, decreasing of fisheries production, and destruction of mangrove forest ecosystems in coastal areas. The government has appeal for the prohibition of sand mining, but extraction still happening. This study aims to assess the policy strategy to overcome beach sand mining throughmotivation and perception of community using SWOT analysis;estimation of actual production costs and estimation of real production of traditional sand mining using descriptive quantitative. The result showed that motivation of community selling sand for economic demands, does not need to work hard, the production are stable and high prices than agriculture activity. They consider selling sand is a side job. If there is no demand for sand, then the community will be doing another job like hunting, fishery and agriculture activity. The community aware negative impact of sand mining and its knowledge become strength effect to a prevention of sand mining. Low enforcement of Government and tribe policies. Real data production of excessive extraction three times higher than government data according to sand mining permit. Meanwhile, all sales sand has no permit. The profit margin for sales agent sand Rp543.111,00/ret while community received Rp250,000.00/ret. Price proposed by internalizing the externalities for sand mining is Rp391.924,00/m3.

Abstract:

The paper presents the results of simulating the impact of sand mining on sediment transport and morphological change in Hai Phong coastal area based on Delft3D model. Scenario groups are established: Present scenarios without sand mining and simulated scenarios of the present sand mining (assuming 30% sand compared to plan). The scenario groups are calculated in the dry and rainy seasons for main wind directions (NE, SE, SW) in the case of moderate wind and strong wind. The results show that sand mining reduces sediment flow alongshore (2–81%) and seawards (5–83%). Besides, the increase in depth causes morphological change in this area: Rising the deposition rate (5–10 mm/month) at the sand mining locations; decreasing accretion rate and increasing the erosion rate in the neighboring areas of sand mining location.

Abstract:

Sand mining is one of the major sustainability challenges of the 21st century. Rates of extraction are surpassing sand supply, and ensuing sand starvation is adversely impacting channel-floodplains and deltas. Therefore, quantifying sand mining’s location and extent, through global monitoring and detection, particularly in fluvial systems, is becoming a priority. Sand mining by dredges and barges (extraction of sand and secondarily gravel) in South East Asian rivers, including illegal sand mining, has become rampant, and a monitoring system is not yet in place. Here, we present a high-resolution remote sensing-based mining monitoring system for sand mining in fluvial systems. We used Sentinel-1 mission, a radar component of the Copernicus joint initiative of the European Commission (EC) and the European Space Agency (ESA). The system, tested in the Ayeyarwady, the second largest river in SE Asia, detects sand mining by barges almost in real-time with a satisfactory accuracy level. An additional advantage of the monitoring system is that it does not incur any costs, making it accessible to multiple users, decision-makers, and stakeholders.

Abstract:

With the accelerated pace of urban construction in Hainan province, demand for building sand increased rapidly, river sand prices soared. This led to the illegal and unauthorized sand mining continue to emerge at Nandu River downstream segment. The current sand mining situation of Nandu River downstream section was expounded. The various impacts of sand mining activities on river regime, flood safety, hydrodynamic characteristics of the river, development of delta and water environment have been studied according to measured data and results of field investigation. It is shown that sand mining activities undermines the natural evolution of the river regime; affects the habitat of fish and other aquatic organisms. Water level drops, water velocity decreases, and the Nandu Rive delta coastline retrogrades due to sand extraction. Besides, sand mining has an obvious adverse impact on infrastructures, waterway safety and social stability.

Abstract:

Abstract. The study focuses on the sand mining activities and morphometric dynamics of Ologe Lagoon, in Lagos, Nigeria. It determines the sand mining activities and morphometric dynamics of Ologe Lagoon catchment area, the quantity of sand mined per unit time, and the extent of environmental degradation due to the continuous sand mining activities. Topographic maps of the 1985 and 2013 Ikonos satellite imagery were used to identify the morphometric dynamics of the area. Two hypotheses were generated to determine if there are significant differences between the means of the sampled population that lost properties due to flooding, and to determine if there was a correlation between building subsidence and loss of property; it was tested using Analysis of Variance (ANOVA) with a correlation coefficient at 0.05 α significance level. The results of geometric measurement of the Ologe Lagoon between the two years interval show that perimeter width and circularity of the basin had reduced and shrunk, while the form factor remains the same at 0.15 km2. The basin elongation increased significantly by 0.01 km2, thus, increasing the rate at which water will be supplied to the lagoon. The ration of the form factor of 0.69/0.5 is close to the unity value R1, which shows a higher peak runoff; the values of the circularity ratio of 3.94/3.13 indicates circularity. This shows that the basin is circular time. The impact of the geometry indicates the development of mud flats and sandy bars, particularly at the lower portion of the lagoon; there is also modification of sediment deposition. The anthropogenic activity of sand mining causes destruction of the riparian forest around the lagoon. There is no significant difference in the means of sampled respondents regarding loss properties due to flooding, while there is a correlation between building subsidence and loss of life. It is recommended that a road map should be developed and implemented by the relevant agency of the government to guide anthropogenic activities around the lagoon to enhance sustainable development.

Abstract:

Sand mining, among the many activities that have significant effects on the bed changes of rivers, has increased in many parts of the world in recent decades. Numerical modeling plays a vital role in simulation in the long term; however, computational time remains a challenge. In this paper, we propose a sand mining component integrated into the bedload continuity equation and combine it with high-performance computing using graphics processing units to boost the speed of the simulation. The developed numerical model is applied to the Mekong river segment, flowing through Tan Chau Town, An Giang Province, Vietnam. The 20 years from 1999 to 2019 is examined in this study, both with and without sand mining activities. The results show that the numerical model can simulate the bed change for the period from 1999 to 2019. By adding the sand mining component (2002–2006), the bed change in the river is modeled closely after the actual development. The Tan An sand mine in the area (2002–2006) caused the channel to deviate slightly from that of An Giang and created a slight erosion channel in 2006 (−23 m). From 2006 to 2014, although Tan An mine stopped operating, the riverbed recovered quite slowly with a small accretion rate (0.25 m/year). However, the Tan An sand mine eroded again from 2014–2019 due to a lack of sand. In 2014, in the Vinh Hoa communes, An Giang Province, the Vinh Hoa sand mine began to operate. The results of simulating with sand mining incidents proved that sand mining caused the erosion channel to move towards the sand mines, and the erosion speed was faster when there was no sand mining. Combined with high-performance computing, harnessing the power of accelerators such as graphics processing units (GPUs) can help run numerical simulations up to 23x times faster.

Abstract:

This study aims to obtain information about the causes of the rise of sand mining on the coast of Batauga, South Buton Regency. This research uses a qualitative research design with a descriptive analysis method by describing it as it is about the reality obtained in the field. Data collection is done through observation and interview techniques. The results showed that the cause of the rise of sand mining in the Batauga District was caused by several factors, namely: 1). Low level of education and economic factors, sand mining activities do not require special expertise and can make money in a short time unlike farming or fishing, 2.) Lack of understanding and awareness, the community is relatively unaware of and aware of the long-term risks of mining sand, the conviction of the miners if the beach sand will never run out, and the belief that the coastal area is claimed the land as private property so that it has become the community's right to process it 3). Lack of socialization and no penalty (sanctions) for miners, 4). The existence of omission and granting of mining licenses from the government (legality) by withdrawing fees from sand mining.

Abstract:

While sand has become a scarce essential resource for construction and land reclamation worldwide, its extraction causes severe ecological damage and high social costs. To derive policy solutions to this paramount global challenge with broad applicability, this model-based analysis exemplarily studies sand trade from Southeast Asia to Singapore. Accordingly, a coordinated transboundary sand output tax reduces sand mining to a large extent, while the economic costs are small for the sand importer and slightly positive for the exporters. As a novel policy implementation approach, a “Sand Extraction Allowances Trading Scheme” is proposed, which helps sustainably balance the importer’s economic growth with the exporters’ economic development.

Mining activities has grown very much, a given result is very given an advantage for the miners. Nevertheless, activities which promise this also also bring an adverse impact on man and the environment when this activity was undertaken not based on the regulation that has been set. Mining illegally also occurred at the sandbanks Parangtritis, sandbanks I know about the Parangtritis are unique and useful for maintained because it is being very specific with the form of a crescent or bacon and is the one and only sandbanks found in the southeast Asia. Arrangement about mining activities that environmentally sound has set out in various regulation, but this appears to have not run as expected, so may is still needed law enforcement tighter and clear to mining sand conducted an illegal. The research was conducted by juridical normative is the approach that was undertaken based on material law by means of reviewing the theory, the concept, a normative law and the regulatory legislation that deals with this research. This approach is known the approach literature, namely by studying books, regulation and other documents related to this research. Criminal law enforcement of the mining sand illegally in sandbanks Parangtritis has started to walk but not yet optimal .The laws governing about mining sand has been is in a few rules, but the law enforcement not is the responsibility of law enforcement officials just, law enforcement is also a responsibility community in an effort to ahead and recover crimes sand mining illegally. Obstacles faced by law enforcement in dealing with crimes sand mining illegal in sandbanks Parangtritis are the lack of legal awareness to the community, economic factors, the lack of knowledge of the community towards the impact of mining sand illegally and factors law enforcement.

Abstract:

This paper presents a review of solid particles size effect on thermocline storage performance for Concentrating Solar Power (CSP) storage systems. After an overview on the different process to store thermal energy we found that a particle size of 2cm diameter is better to achieve a good sensible heat storage performance within a system call dual-medium thermocline (DMT). The thermal storage potentiality of different sands from Burkina Faso have been carry out to look at the possibility to make a filler material with 2cm diameter. However, two different sands (mining dune and river sand) properties have been assessed. The density of the two samples is more than 2650kg.𝑚−3 with low mass losses at 700 ℃ without any agglomeration at 900 ℃ and 1000℃. This indicates that the mining sand samples from Bobo Dioulasso and Dune sand from Sahel region in Burkina (Oursi) have the potentials to be used to develop an effective thermal energy storage material or to store thermal energy at high temperature.

ABSTRACTTondasi Village is one of the Villages in the North Tiworo Sub-District West Muna District as a producer of sand extraction. This study aims to find out: (1) Sand mining business in Tondasi Village, North Tiworo District, West Muna Regency; (2) Determine what factors cause people to change their livelihood patterns. The sample in this study used the Non Probability Sampling technique that was chosen which was saturated sampling (census). In this study, the samples taken were 229 Tondasi villagers. Data were analyzed with 3 stages, namely data reduction, data presentation and conclusion. The results of this study show that sand mining in Tondasi Village initially used traditional tools, but technological development is increasingly rapid, so sand mining in Tondasi Village uses a sand suction machine. There are 3 factors that cause the community to change their livelihood to become sand miners, namely the income factor, the lack of catches for the people who are fishermen background, and the failure of the crop due to uncertain seasonal factors for the people who are farmers. However, there are 3 factors that have caused the community to leave their livelihood as sand miners, namely the emergence of new technology to mine the sand which makes traditional sand miners unable to compete with miners who use vacuum cleaners, the absence of mining permits from the government and the emergence of awareness about the importance of protecting the environment.Keywords: Sand Mining Business, Livelihood Changes

Abstract:

This study uses the Islamic legal approach with qualitative research methods with techniques for collecting data through observation, interviews, and documentation. The research aims to reveal the commercialization of sand mining in Koto Kandis Village, Dendang District, East Tanjung Jabung Regency, and see how Islamic law views the sand mining activities carried out by the community in Koto Kandis. Based on the research carried out, the results are as follows: First, the process of commercializing sand mining is carried out by the Kandis City farmers using water and land lines. Second, this sand mining has positive impacts such as being able to increase economic income and help meet children's educational needs and deepen river water for smoother waterway trips. The negative impact of sand mining is road damage, air pollution due to dust, increased noise due to sand transport trucks, and a decrease in water quality due to sand mining. Third, in the view of Islam, natural resources in its essence belong to Allah's absolute mandated management, utilization and preservation to humans. In the management, exploration and exploitation of natural resources must pay attention to the preservation of nature and the environment and the sustainability of development. In the process of commercializing sand mining that occurs in Koto Kandis Village can be viewed from various aspects included in Islamic law including: Judging from the Word of Allah SWT in the Qur'an, Judging from the Word of the Prophet Muhammad, Judging from the Fatwa of the Indonesian Ulema Council (MUI) , Judging From the Istinbath Method of Islamic Law, Viewed From the Muhammadiyah Tarjih, Judging From the Principles of Fiqh.

Abstract The subject of the study is the improvement of the quality of moulding sand preparation. An exploration research performed on the data concerning moulding sand quality parameters was described. The aim of the research was to find relationships between various factors determining the properties of moulding sands and, based on the results obtained, build models predicting the sand moisture content with the induction of classification and regression trees. A two-match prediction approach was demonstrated and its effectiveness in evaluating the moulding sand moisture content was discussed. The knowledge in the form of rules acquired in this way can be used in the creation of knowledge bases for systems supporting decisions in the diagnostics of the moulding sand rebonding process. Formalized knowledge also facilitates further processing of the measurement data.

Abstract:

In western region of China, the water-sand inrush across overlying strata fissures caused by mining threatens the mine safety production seriously. In order to study the development of water-sand inrush across overlying strata fissures caused by mining, a simulated test system consisted of load support bracket, laboratory module, confined water module, coal seam mining simulator, storage tank, and control system is developed. The combination of coal bearing strata in the south of Shendong mining area is looked on as the engineering background, and a series of new nonhydrophilic composite materials with lower intensity are developed to simulate the coal measure strata. The excavation of physical model can reproduce the whole process of water-sand inrush across overlying strata fissures caused by mining to the life. Under the action of mining and water pressure, after the fourth excavation, the mining-induced vertical fractures of overlying strata pass through the entire bedrock and connect the unconsolidated sand bed, which serves as pathways between the unconsolidated sand bed and working face, triggering water-sand inrush. The water pump suddenly accelerates, and the water yield suddenly increases to the extreme value of 150 L/h. The water pressure rapidly drops to 0 MPa, and a small amount of colored sand enters into the fractures of overlying strata and flows out with the water. The distribution of support pressure around the working face can be divided into 4 areas obviously, that is, the original stress area, the stress-concentrated area, the stress-released area, and the stress restoration area. Test results show that the system is stable and reliable, which have important significance for studying the formation mechanism of water-sand inrush across overlying strata fissures further.

Abstract:

Indonesia is a country with abundant natural resources, including those with enough potential, namely the mining sand industry. Mining on a large scale is good for economic growth, but vice versa on the environmental impacts caused. Environmental damage due to exploitation also occurred in Brumbung village, Kediri district. Environmental damage caused by existing sand mining creates problems that must be claimed by all parties. This paper examines how the impact caused by sand mining activities on the surrounding environment. This type of research is descriptive-qualitative, where the research process and understanding are based on the methodology that investigates a phenomenon. To study this problem, observations and questions and answers were made to the miners, the surrounding community and also the relevant offices. The observed location is around the Brantas River where there are sand mining activities in Brumbung Village, Kepung Subdistrict, Kediri District. research in the area is motivated by the phenomenon of the large number of illegal sand mining in the Brantas river, especially in the self-inflated village, which has many pros and cons in the surrounding community. The environment itself is all things, conditions, conditions and influences that are in the space we occupy and affect the things that live, including human life. Population growth has increased the need for clothing, food, shelter, clean water and energy. This results in higher exploitation of natural resources and tends to neglect environmental aspects. Therefore there is a need for research on the study of environmental impacts, both physical and socio-economic activities of sand mining in the berumbung village, in order to obtain an overview of the environmental impacts that occur or will occur. Later this research is to be taken into consideration in making policies related to the problem of sand mining.

One type of instant economic activity includes being sand miner and sand transporter in the sand mining area. The purpose of this study is to describe the impact of children's productive activities in the sand mine on dropout rates at the junior high school level in Keduwang Village, Blitar Regency. Respondents of the research data amounted to 38 children who carried out productive activities of sand mining. This study used cross-sectional survey research method with a quantitative approach that were supplemented with qualitative data. The collection technique used questionnaire, observation, and interviews. Data analysis techniques used descriptive data analysis techniques with the odds ratio method. The results indicate that the impact of children's productive activities in sand mining on dropout rates at junior high school level with decrease of children’s interest attending school. The results of odd ratio analysis indicate that the riskiest factor causing children to choose school dropout is productive activities in sand mining do not require special skills. The factor of not requiring special skills is proven to be six times the risk of causing children school dropout. The results provide description of how easy economic access and does not require skills has an impact on children's perceptions of going to school or working. Implications for the results of this research are expected to be a reference for government to pay attention to dropout rates that occur due to the productive activities of children in sand mining.

Abstract:

River sand mining has been a concerning problem for the southern Asian developing nations. The rampant growth of urbanisation in developing countries has led to an extensive need for and consumption of sand. The Mekong River and its delta are an essential part of southern Vietnam, and also a global biodiversity hub that is currently being exhausted by intensive sand mining. The understanding of the cause–effect of the sand mining over the Mekong delta region and river, from a systems-thinking perspective, is lacking, not only with Vietnam but also with other countries along the Mekong River. The DPSIR framework (Driver–Pressure–State–Impact–Response) is a useful tool to assess and describe the cause–effect within an ecosystem to aid in a better systems-thinking approach for stakeholders, policy makers, and governance managers to draft response measures. This study used the DPSIR framework to assess the different effects of sand mining on the ecosystem services and human well-being in the Mekong River and delta region of Vietnam. Rapid population growth, urbanisation, and infrastructure development needs remain as primary drivers for the sand consumption. The DPSIR study showed a holistic view of several interlinked pressures and state changes in Vietnam’s Mekong, along with some potential responses, to form systematic, sustainable approaches for mitigating and adapting the impacts caused by extensive river sand mining.

Abstract:

With the continuous increase of the upper limit of coal mining, in mining areas near unconsolidated layers, water and sand inrush disasters occur from time to time, seriously threatening the safety of mine production. In this paper, the process of water and sand inrush accidents induced by mining near unconsolidated layers is analyzed using mechanical analysis and numerical simulation methods, based on the principle of silo unloading and arching and combined with actual water and sand inrush characteristics; the critical water and sand inrush arching mechanism is explained. The paper also proposed and established three critical arching mechanics models (interlocking arch, bonded arch, and transition arch), deduced the mathematical expression of interlocking arch and transition arch, and obtained the critical instability conditions of the arch and its influencing factors. The research results have guiding significance for the occurrence of water and sand inrush disasters and the judgment of the degree of damage in mining near unconsolidated layers.

Abstract:

Driven by hydraulic fracturing, sand mining has expanded rapidly in western Wisconsin, with hundreds of mining operations appearing over the past several years. Silica sand is extracted from hills and then shipped by rail around the country, where it is pumped under high pressure with water and chemicals into oil and gas wells. An often overlooked dimension of America's unconventional energy boom, the growth of sand mining in Wisconsin has been incredibly divisive, generating wealth for some lucky landowners while creating new environmental hazards for others. This article documents how people experience mining-related changes and conflicts, drawing on ethnographic interviews with residents living next to mines, processing plants, and hauling routes. While not everyone experiences mining equally, I argue that people grappling with a sudden influx of mining activity suffer significant disruptions that erode their sense of place and belonging. These experiences, however, are rarely taken into account by policymakers, local officials, or others seeking to evaluate the costs and benefits of frac sand mining. This omission underscores the need for ethnographic research to deepen our understanding of how people are impacted by new resource extraction industries.

Abstract:

In this study, the slope piping experiment selected 6 different sands in mining engineering of civil construction. In addition to discussing the physical parameters of the graded sands in mining engineering, the piping destruction parameters of different slopes were obtained from the experiment. When piping occurs, we can use numerical model to get the hydraulic gradient value at the failure point. The difference between the theoretical estimation and the numerical model was compared and we found that different particle size distribution caused the main difference. The particle size parameter ratio, D*, is used for correcting the critical hydraulic gradient value in this study. We learned the correction coefficient of D* is between 0.5~0.857 in different tests and its value approximates the reciprocal of the coefficient of uniformity. Therefore, the critical hydraulic gradient estimation formula for the slope piping of the uniform sand can be future corrected, and it can be used for estimating the graded sand in this study. In civil engineering the sand filling project can use the estimation formula of this study to calculate the critical hydraulic gradient as the reference for design and disaster prevention.

Abstract:

Copper mining in the Upper Peninsula of Michigan in the mid-19th century generated millions of tons of mining waste, called stamp sand, which was deposited into various offshoots of Lake Superior. The toxic stamp sand converted the area into barren, fallow land. Without a vegetative cover, stamp sand has been eroding into the lakes, adversely affecting aquatic life. Our objective was to perform a greenhouse study, to grow cold-tolerant oilseed crops camelina (Camelina sativa) and field pennycress (Thlaspi arvense) on stamp sand, for the dual purpose of biofuel production and providing a vegetative cover, thereby decreasing erosion. Camelina and field pennycress were grown on stamp sands in columns, using compost to supply nutrients. A greenhouse study in wooden panels was also done to evaluate the effectiveness of camelina in reducing erosion. Results show that camelina significantly reduced erosion and can also be used commercially for generating biodiesel. A 25-fold reduction in Cu content in the surface run-off was observed in the panels with camelina compared to those of the control. Stamp sand-grown camelina seeds contained 20% and 22.7% oil and protein respectively, and their fatty acid composition was similar to previous studies performed on uncontaminated soils.

Abstract:

In many developing country’s mining exploitations are the main activities sources, and its exploitation is generating many mining wastes and environmental impacts. In order to use these waste, an innovative powder and aggregate were designed, aimed at providing alternative materials by cementitious supplementary materials and sand in Portland cement mortars. This paper investigates the use of raw mineral waste from some developing countries, namely Granite Residue (GR), from Niger, Mining Tailings (MT), from Madagascar, and red Volcanic Scoria (VS), from Cameroon as building materials. These raw materials were valorized as supplementary cementitious materials (GR powder, MS powder and VS powder) and as sand (GR sand and VS sand). GR sand and VS sand were used by 100% replacement of standard sand and GR powder, MS powder and VS powder were used by 5, 15, 25, or/and 35% cement replacement. Physical properties and mechanical properties of raw materials used and mortars obtained were investigated. The effects of these raw materials on properties of mortar mixes were studied and reported. Results show that, with sand from raw mineral waste materials, the compressive and flexural strengths of the produced mortar represented up than 70% and up than 85% respectively in comparison with mortar produce with siliceous standard sand. The reduction of strength of mortar with raw powder as ordinary Portland cement replacement is generally smaller than replacement ratio. Activity index of each raw powder is about 75% for ratio replacement of 5, 15 and 25%. Particle size distribution of raw powder and sand have an influence on the workability and mechanical properties of mortars. In conclusion, the use of raw mineral waste as a raw powder or as sand for mortar production presents an economical and environmental advantage for developing countries where mining exploitations are abundant.

Abstract:

The coastal hydrogeological model of iron ore prospect area in Widarapayung coastal, Cilacap Regency, has been designed and performed based on the 2D-resistivity data. The background of this research is potentiality of iron sand in this area and its prospect to be mined. Mining activities in large-scale may lead into surface decreasing, triggering damage to the aquifer, abrasion, and saltwater intrusion in the coastal area. The acquisition of 2D-resistivity data has been performed on five trajectories including of WP-01 up to WP-05. Based on the modeling results, it can be concluded that the sub-surface rocks resistivity profile consists of WP-01 with the values of 1.93-114.00 Ωm; WP-02 with the values of 3.67-121.00 Ωm; WP-03 with the values of 3.86-78.40 Ωm; WP-04 with the values of 1.79-100.00 Ωm; and WP-05 with the values of 2.61-86.20 Ωm. After interpretation, it is found that the hydrogeological profile of sub-surface rocks consists of sand inserted with gravels (topsoil); sand containing iron ore granules inserted with silt (topsoil and shallow aquifer); clayey sand (semi-aquifer layer); sandy clay (semi-impermeable layer); and sand (deep aquifer which is intruded by salt water). Based on the analysis, the sand containing iron ore is part of the shallow aquifer, so the mining activities of iron sand is potential to damage and reduce aquifer function in storing and flowing the groundwater in the research area.

Abstract:

Soil nitrogen is a key indicator of soil quality and plays a significant role for plant growth. Therefore, it is very important to study soil nitrogen distribution, especially in semi-arid area of western China. Fewer scholars paid attention to the effect on soil nitrogen due to coal mining in semi-arid mining areas of western China. In this paper, soil samples of different locations were tested in both the loess region and the aeolian sand region in the Daliuta mining area in Shaanxi Province. The impacts of mining subsidence on soil nitrogen were investigated. The soil nitrogen distributions between the loess region and the aeolian sand region were compared, and used the principal component analysis method to evaluate soil quality in semi-arid mining area. The results showed that the comprehensive score of soil quality in the loess region was as follows: the internal pulling stress zone (NLS) > the external pulling stress zone (WLS) > the compressive stress zone (YS) > the neutral zone (ZX). The content of soil total nitrogen in YS-zone was the lowest in the loess region. The loss of nitrogen increased with time in the mining area, in which the total nitrogen loss at the depth of 0−15 cm was 0.27 g/kg, and the alkaline nitrogen loss at the depth of 0−15 cm was 1.08 mg/kg. In the aeolian sand region, the comprehensive score of soil quality was as follows: WLS > FC (the non-mining zone) > ZX > NLS > YS. The amount of soil nitrogen content in the loess region was larger than that in the aeolian sand region. It was found that for the loess region, the relationship between total nitrogen and nitrate nitrogen showed a significant positive correlation. It was also a significant positive correlation between ammonium nitrogen and alkaline nitrogen. In the aeolian sand region, there was a significant positive correlation between total nitrogen and alkaline nitrogen. There was no significant correlation among other nitrogen forms.

Abstract:

One of the primary objectives of the Canadian Liquefaction Experiment (CANLEX) project was to evaluate in situ testing techniques and existing interpretation methods as part of the overall goal to focus and coordinate Canadian geotechnical expertise on the topic of soil liquefaction. Six sites were selected by the CANLEX project in an attempt to characterize various deposits of loose sandy soil. The sites consisted of a variety of soil deposits, including hydraulically placed sand deposits associated with the oil sands industry, natural sand deposits in the Fraser River Delta, and hydraulically placed sand deposits associated with the hard-rock mining industry. At each site, a target zone was selected and various in situ tests were performed. These included standard penetration tests, cone penetration tests, seismic downhole cone penetration tests (giving shear wave velocity measurements), geophysical (gamma-gamma) logging, and pressuremeter testing. This paper describes the techniques used in the in situ testing program at each site and presents a summary and interpretation of the results.Key words: CANLEX, in situ testing, shear wave velocity, geophysical logging, pressuremeter.

Abstract:

Sand mining activities in Pasir Sakti District, East Lampung Regency, have changed the landscape and the allotment of land around it. The former sand mining area now becomes large puddles that are not utilized. This study aimed to analyze the suitability of water quality in ex-sand mining areas for tilapia (Oreochromis niloticus) culture. Observations were carried out at three stations in January-October 2019. Water quality measurements were performed to check water depth, clarity, temperature, current, dissolved oxygen, pH, salinity, nitrate, phosphate, iron, sulfate, and phytoplankton density. Analysis of suitability for aquaculture was carried out using weighting and scoring methods. Based on the results of the suitability analysis, the scoring result of the sand mining land for O.niloticus culture was in the range of 64% -68%. This score is classified as marginally suitable. The parameters with low scores are clarity, dissolved oxygen, temperature, pH, ammonia, phosphate, and iron (Fe) concentration parameters. Meanwhile, salinity, nitrate, sulfate, and phytoplankton density indicate conditions that are suitable for aquaculture. Therefore, severe treatment is needed to improve water quality to make it ideal for O.niloticus culture.

Additionally, community involvement in rehabilitating and reforesting former mining areas contributes to recovery should be imposed. These parties' environmental damage control efforts have been less than optimal due to impeding factors such as a lack of institutional coordination or cooperation among the parties responsible for implementing the control and the absence of strict sanctions against illegal sand miners Contribution: The author proposes a review of existing control programs and increased enforcement efforts against illegal sand miners.

Abstract:

The aim of this paper is to reveal the dynamics of public policy implication of sand mining in Lumajang Regency. Public policy become a key point of investment movement. Qualitative with phenomenology approach is used. The finding of this paper is the system of SKAB becomes a problem source of sand tax leak take. Letting the column of the tonnage/volume of sand released blank became a strategy for miners to minimize the taxes they must submit to the BPRD, whereas it was the basis for taxation. Duplication of SKAB was what the authors believed as the main cause of a substantial sand tax leak where the taxpayers who were authorized by the BPRD should be able to be responsible for the SKAB. This research could be basic consideration for government to make sand mining public policy correction in order to improve regional original income (PAD).
