Mining and Extraction Environmental Services SCS EngineersRespiratory Diseases Caused by Coal Mine Dust

Mining and Extraction Mining involves environmental challenges such as impacts on local ecosystems and potential water pollution Modern mining operations are doing their part to minimize impacts and environmental specialists like SCS Engineers can help design build then thoroughly operate and monitor programs in order to minimize environmental impacts and help prevent accidentsCoal is an important global commodity and will remain so for the foreseeable future Thus mining of coal will also remain important Despite improvements in exposure assessment and ventilation controls and the existence of protective government regulations coal miners are still at risk for respiratory diseases caused by coal mine dust and their associated morbidity and mortality

Water Resources Utilization and Protection in the Coal Mining induced strata stress changes fractures and gas

The biggest difference between water resource utilization and management in coal mining area and other region is that the supply of water resources for coal mining area is severely affected by To implement the co extraction of coal and methane a clear understanding of mining induced strata stress changes fractures and gas flow are essential To date extensive studies in these areas have been carried out for various purposes such as mine ground control water inrush prevention and gas control respectively

Logistics in underground mining a close examination Merits of open pit versus underground mining in the future

This report reviews the status of many Bureau projects that support fundamental underground coal mining operations the project areas include cutting coal from the solid extraction hauling coal from the face transport and activities that sustain daily operations logistics Other advantages of open pit mining are lower working force requirement greater safety elimination of ground support and ventilation problems more complete extraction greater opportunity for selective mining send grade control send the recovery during stripping of small isolated ore blocks not suitable for extraction by underground methods

A review of mechanism and prevention technologies of coal Annular overlying zone for optimal gas extraction in multi

However an optimal mining design is critically important for the purpose of coal bump mitigation It should be especially noted that optimal mining design such as designs of protective seam mining non pillar mining optimal layout of the mine and the pre excavation of stress relief tunnel is of significance for the prevention of coal bumpsCo extraction of coal and methane is the future trend of efficient coal mining It effectively combines the two previously separate operations of extracting coal and methane gas The coal mining operation will enhance desorption and migration of methane in surrounding coal seams as is necessary for gas extraction
