·1 INTRODUCTION Mine water treatment always plays an important role in the coal mining regions especially in the arid to semi arid zones Navarro et al 2008 of western China such as Ordos Basin and Tarim recede the threat of mine water hazard from roof aquifers a large number of alkaline saline mine water drainage projects
·The exploitation of coal resources has disturbed the equilibrium of the original groundwater system resulting in a perturbation of the deep groundwater dynamic conditions and hydrochemical properties Exploring the formation of mine water chemistry under the conditions of deep coal seam mining in the Ordos Basin provides a theoretical
·Mines are known to cause severe environmental problems Mining is the extraction of minerals and other geological materials of economic value from deposits on the Earth Mining adversely affects the environment by inducing loss of biodiversity soil erosion and contamination of surface water groundwater and soil
·It is therefore imperative for both companies and governments to manage the environmental and social impacts of mineral production Companies have a clear business case to address these harms to reduce risk and maintain a social license to operate Consumers and investors are increasingly demanding that companies take
·The scarcity of water resources and environmental pollution in the coal mining areas of western China severely restricts high quality mine development and construction there Treating mine water as a valuable unconventional water resource for large scale processing and efficient utilization is a crucial approach This paper discusses
·Coal and organic rich shale in the Yan an Formation in the southwestern margin of the Ordos Basin are widely developed which is an important fact for oil and gas exploration in China that has been widely explored for a long time In this paper detailed sequence division and sedimentary environment analyses of the Yan an Formation in the
·The northern Ordos Basin is one of the biggest uranium resource production areas in China However the hydrogeochemical mechanism for the formation of uranium deposits remains poorly understood despite that interlayer oxidation hydrothermal fluid mineralization and gas reduction were proposed In order to provide a more
·Prior studies have indicated that mining induced surface dynamic cracks in eastern China only undergo one expanding closure development cycle However field measurements from the Bulianta mines of northwestern China demonstrated that ground dynamic cracks in the Ordos region went through two expanding closure cycle Using in
·By working with communities in mining areas Odell and Fernández are gaining a sense of the burden that mining minerals needed for the clean energy transition is placing on local populations and the types of conflicts that arise when water sources become polluted or scarce These trends have brought major attention to issues of
·The hydrogeological conditions in the Ordos Basin differ greatly between east and west so also do the water inrush patterns and prevention methods during mining
·The H<sub>2</sub>S anomalies occurred during the construction and trial production of the Ya Dian coal mine in the northern part of the Binchang mining area in the southern margin of Ordos Basin During excavation the maximum is about 140 ppm and H<sub>2</sub>S overrun often occurs in fully mechanized working face of the first mining
·mining industry sponsored the Mining Minerals and Sustainable Development Project the stated intention of which was to determine how best the industry could contribute to sustainable development Daniel 2015 This paper seeks to review the issues and prospects of solid mineral mining in the Nigerian context
·The Ordos basin is in the western part of the North China Block and the study area is in the southwest part of the basin also known as the Longdong area The Carboniferous system has many bauxite rocks with burial depths of approximately 3500 5000 m which are generally regarded as the cap layers of the weathering crust gas
·Combined with theoretical analysis numerical simulation and field measurement it is shown that the stress level of the Ordos deep mining area is higher than that of the shallow original rock
·In China the first CO 2 capture and geological storage CCGS demonstration project was constructed in the Ordos Basin of Inner Mongolia in 2010 Li et al 2013;Liu et al 2014
·The vast realm of small artisanal and illegal mines that are not bound by standard reporting requirements is a global problem The extent of small scale mining on mineral production varies
·Sudden inrushes of mine water from coal roofs threaten the safe production of coal in China s northern Ordos Basin However due to similar hydrochemical characteristics routine hydrochemical analysis fails to discriminate the water sources In this study a new method based on the characteristics of dissolved organic matter DOM the
· Data sources The effective operation of the economic system relies on mineral resources to provide the material basis Therefore the economic system and the development trend of the energy and mining industry are synchronized Han et al 2021 Since the ecological base impacts of economic development are manifested with a
In a CO 2 storage project CO 2 may be able to escape from channels caused by the formation s uplift fault reactivation and wellbore failure owing to overpressure build‐up and likewise coal excavation during which equilibrium disruption of stress could possibly lead to floor heave roof collapse and surface subsidence When the carbon capture and storage
The major environmental problem with underground mining is the hazardous working environment for miners primarily caused by cave ins and lung disease due to prolonged inhalation of dust particles We also need to maximize exploration for new mineral resources while at the same time we minimize the environmental impact of mineral
·Mineralogy and geochemistry of the Middle Jurassic coal from the Hexi Mine Shenfu Mining Area Ordos Basin With an emphasis on genetic indications of siderite Siderite is a common carbonate mineral in coal and usually contains geochemical indications elemental associations and isotopic compositions for sedimentary
·The depletion of non renewable natural resources primarily mineral and energy resources and its assessment is a problem that is analyzed based on the concept of sustainable development
Ordos is notoriously represented in media discourses as one of China s principal ghost cities with skyscrapers apartment estates and grandiose squares largely unoccupied The ghost city emerges from massive over investment in the urban built environment Aware that economic and financial sustainability are in question we nonetheless choose to
