Research on Comprehensive Prevention and Control of Water Damage in Coal Mine Working Face
The E9102 working face of Hengjin Coal Industry is near Nanshan syncline.Due to the influence of the syncline,the water in the overlying aquifer on the working face is locally enriched.The mining is expected to be mainly affected by the overlying aquifer on the roof and the structure of water conducting faults.Through a series of comprehensive water prevention and control measures such as advanced geophysical detection,drilling exploration to verify drainage,reasonable layout of drainage system,and surface drainage,the safe recovery of the working face is effectively guaranteed,while alleviating the drainage pressure in the mining area and saving drainage costs,achieving certain economic and social benefits.
