摘要
矿区地处秦岭褶皱带内天水-西礼构造盆地,地下水类型可分为第四系松散岩类孔隙水、第三系碎屑岩类孔隙裂隙水及石炭系基岩裂隙水三种。三号矿带各中段涌水量只随开采水位降低值变化而变化,四号矿体随着开采中段的推进,矿井涌水量也逐渐增加,金矿开采对区域地下水环境影响较小。研究结果为以后的地质勘查提供一定的参考。
The mining area is located in the Tianshui-Xilei tectonic basin in the Qinling fold belt.The groundwater types can be divided into Quaternary loose rock pore water,Tertiary clastic rock pore fissure water and Carboniferous bedrock fissure water.The amount of water in the middle section of the No.3 ore belt only changes with the decrease of the mining water level.With the advancement of the middle section of the mining area,the amount of water in the mine is gradually increasing,and the impact of gold mining on the regional groundwater environment is small.The research results provide some reference for future geological exploration.
