Study on hydrogeological characteristics and Mining Technology of a mine in Hubei Province
The hydrogeological background of the mining area is the water-separated environment of granitic gneiss series and Silurian shale series of Lower Paleozoic.The regional groundwater and the mining area groundwater are closely connected along the strike through the dolomite aquifer of Sinian Dengying Formation,forming the hydrogeological conditions of interlayer runoff and drainage along the strike.The mining area belongs to the dissolved fissure water-filled deposit,and its ore-bed is developed,mostly with strong water-rich and good water conductivity,forming strong structural vein water,which communicates the hydraulic connection between various aquifers,may cause the deposit water-filled,unfavorable mining.According to the occurrence conditions of ore bodies,the mining method is determined as shallow hole(stratified)house-pillar mining method,and the stopes are all mined by electric harrow.For the ore body with a thickness of less than 3.5m,it can be mined at one time with full thickness,and for the ore body with a thickness of more than 3.5m,it can be mined by layers.
