煤矿斜井过第四富含水层深井井点降水法应用研究

Application research of well point dewatering method for deep well passing the fourthrich aquifer in inclined shaft of a mine

为了解决矿井斜井开拓过程中由于第四系松散富含水层的影响,严重阻碍矿井的正常建设,威胁施工人员的安全,通过理论分析、数值计算等方法,对其明槽开挖采用深井井点降水进行设计研究,解决了矿井井筒涌水问题和生活、工程用水短缺的问题,从安全和经济两个方面取得了良好收益。

In order to solve the mine in the process of slope development because of the influence of the quaternary unconsolidated aquifer rich, severely hampered the normal construction of the mine, threatening the safety of construction personnel, through the theoretical analysis and numerical calculation methods, the Ming groove excavation using the deep well point precipitation to design research, solve the problem of the mine shaft water gushing and life, engineering water shortage, from two aspects has obtained the good safety and economic benefits.
