煤矿高压水闸墙抗水压安全性研究

Study on Resist Water Pressure Safety of High-pressure Sluice Wall in a Coal Mine

某煤矿21102工作面水闸墙于2002年发生突水事故后砌筑,并于2003年投入使用,水压已由7.55 MPa降至6.7 MPa,水闸墙能否抗得住目前水压力尚无定论。通过理论计算、FLAC3D数值模拟、混凝土质量测试及排水管路抗水压情况等方法和手段对高压水闸墙抗水压安全性进行分析研究。

The high-pressure sluice wall in 21102 working face in a coal mine was built in 2002,and put into use in 2003. The water pressure of high-pressure sluice wall reduced from 7. 55 MPa to 6. 7 MPa. It was uncertain that if the high-pressure sluice wall could resist the water pressure. This paper used methods of theoretical calculations,FLAC3 Dnumerical simulation,concrete quality testing and pipeline anti-pressure situation to study the the safety of the high-pressure sluice wall.
