浅谈工作面采空区积水的治理

摘要

The types of hydro geological are very complicated in coal mines in our country ,and many coal mines are threatened by floods ,so the tasks and pressure of w ater prevention and control are very heavy .T he paper an‐alyzes sources and channels of goaf hydrocephalus in 8101 first mined face ,Selian Colliery ,Erdos ,and proposes governance scheme .After the implementation ,the pressure reduces from 0 .09 MPa to 0 .02 MPa ,head height re‐duces 7 m ,drilling depth reduces from 120 m to 20 m .100 ,000 yuan and the costs of procurement of large pumps (60 ,000 yuan) are expected to save .Successful implementation of the scheme proves that the technology has promotional value in overall performance .%我国矿井水文地质类型非常复杂，很多煤矿受到水灾的威胁，防治水工作任务重、压力大。本文分析了鄂尔多斯色连煤矿8101首采工作面采空区积水的来源和通道，提出了治理的方案。方案实施后，水压从0．09 M Pa降低到0．02 M Pa ，水头高度降低了7 m ，效果良好。该方案的使用将钻探深度从120 m缩短至20 m ，预计节约资金10万元，节省大型水泵采购费用6万元。本方案的成功实施，证明该项技术在总体性能指标上具有推广价值。
