拜城矿区3号矿井第四系水文地质特征

Quaternary Hydrogeological Characteristics of No.3 Mine in Baicheng Mining Area

通过开展钻探和水文孔抽水试验等工作,结合以往水文地质资料,对拜城煤矿区3号矿井第四系水文地质特征综合分析研究,发现矿井范围内第4系基底发育规模不一的古冲沟,规模较大的古冲沟内第四系潜水富水性较强,总结了第四系潜水含水层富水性特征。对矿井今后第四系潜水含水层治理工作具有较好的指导作用,也为具有山前冲洪积扇盖层类似条件的矿井防治水工作提供参考。

Through drilling and hydrological hole pumping test,combined with previous hydrogeological data,compre-hensive analysis and research on the hydrogeological characteristics of the Quaternary system in No.3 Coal Mine in Baicheng Coal Mine Area,it is found that there are ancient gullies with different scales in the Quaternary basement within the scope of the mine,and the Quaternary phreatic aquifer in the larger ancient gullies has strong water yield.The water yield characteristics of the Quaternary phreatic aquifer are summarized.It has a good guiding role for the future treatment of the Quaternary phreatic aquifer of the mine,and also provides a reference for the mine water control work with similar conditions of the piedmont alluvial proluvial fan cover.
