摘要
云南省石屏县法乌铜多金属矿区位于石屏县城北西方向,矿区隶属云南省石屏县龙武镇所辖。其中法乌铅锌矿位于该矿区中南部。在对矿区水文地质特征与矿坑充水因素分析基础上,采用比拟法与裘布依理论式进行矿坑涌水量计算预测。结果表明:法乌铅锌矿矿区水文地质单元面积为28.67 km^(2),地下水形成分布主要受区域性深大断裂建水-石屏断裂带控制。矿区地层划分为第四系冲洪积、残坡积孔隙含水层、裂隙岩溶综合含水层和花岗岩风化裂隙含水层,矿坑充水因素主要为大气降水和地表水;以1522~1246m标高为界,采用裘布依理论式计算法预测矿坑涌水量为630 m^(3)/d,与采用PD91坑道排水量资料比拟法计算的576 m^(3)/d结果相对接近,说明边界条件及参数取值较为合理,计算结果可信;在未来矿区建设生产中,要做好矿坑涌水量的动态监测,对有积水的区域要做好排水工作。
Fawu copper-polymetallic mine in Shiping County,Yunnan Province is located in the north west direction of Shiping County,and the mine is under the jurisdiction of Longwu Township,Shiping County,Yunnan Province.One of these mines,the Faw lead-zinc mine,is located in the south-central part of the property.On the basis of the hydro-geological characteristics of the mining area and the analysis of the pit filling factors,the pit water influx calculation prediction is carried out by using the comparison method and the Jubilee theoretical formula.The results show:The hydro-geological unit of the Fawu lead-zinc mine area covers an area of 28.67 km^(2),and the distribution of groundwater formation is mainly controlled by the regional deep and large fracture Jianshui-Shiping fracture zone.The mining stratum is divided into the Quaternary alluvial and residual slope accumulation pore aquifer,fissure karst synthesis aquifer and granite weathering fissure aquifer,and the water filling factors of the mine pit are mainly atmospheric precipitation and surface water;With the elevation of 1522~1246 m as the boundary,the water inflow of mine is predicted to be 630 m^(3)/d by using the Qiubuyi theoretical calculation method,which is relatively close to the result of 576 m^(3)/d calculated by the comparison method of PD91 tunnel displacement data,indicating that the boundary conditions and parameters are reasonable and the calculation results are credible;In the future construction and production of mining areas,it is necessary to do a good job of dynamic monitoring of mine water inflow,and to do a good job of drainage in areas with stagnant water.
