摘要
矿区水文地质背景为花岗质片麻岩系与下古生界志留系页岩系所构成的东西两侧为隔水边界的环境,区域地下水与矿区地下水主要通过震旦系灯影组白云岩含水层沿走向联系密切,形成沿走向层间径流排泄的水文地质条件。矿区属溶蚀裂隙充水矿床,其矿层发育,多具有较强的富水性和良好的导水性,形成强构造脉状水,沟通了各含水层之间的水力联系,可能造成矿床充水,不利开采。根据矿体赋存条件,采矿方法确定为,浅孔(分层)房柱采矿方法,采场均为电耙出矿;对于矿体厚度小于3.5m的矿体,全厚一次性回采,矿体厚度大于3.5m的矿体进行分层开采。
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.
