Group Of Hole Mine Waterproof Technology Research Into Which The Shi-cao-cun Coal

Based on the dreadful effects a large Ning Dong Shi Cao village coal mine to combat waterworks, This document combines with three research methods including indoor testing, theoreticalanalysis, field-testing. Abide by the regulations of the Coal Mine to combat water, it means theprevention, containment, and alienation, the interception, in the entrance to the water drain in roofaquifers in governance. Major research work and conclusions in the report are:(1) failure on the slit relative growth is better, in bold, sandstone, the aquifer in theapplication. At the Face picking, large-scale and old top-down before falling to drain off water,and can be a large degree of lowering the top-down behind the empty area surge of water quantity,in order to effectively ensure that good security and construction of small, construction ease ofdesign, it would be appropriate to the strong in sandstone aquifers to picking Top of mines.Massive drain drain the mine drainage capacity requirements is high.(2) for sandstone included economic strata characteristics, study the Regional Aquifer towater, the targeted the drain water drain, that is for the more powerful aquifers in the drain waterdrain construction, increase of the aquifer drain on productivity, reduce mining the surface waterconcentration. Lower face plate or alleyways surrounding the aquifer that water flow, thusreducing surface after picking the empty the water or tunnel boring, the surge of water quantity,and production purposes.(3) Base on the above research, the analysis of other Ning Dong mining mines’ aquifercharacteristics, combined with Shi Cao village coal to combat water results in Shi Cao village coalmine and Ning Dong mining of combat water challenges for the reference.
