摘要
演马庄煤矿属于典型的煤与瓦斯突出和突水矿井,突水隐患严重威胁着矿井的安全生产。为了防治突水危害,利用高精度BMS微地震监测技术对矿井突水危险性进行实时预测预报。在该矿27111工作面布置测点,共监测到52个有效微震事件,并在此基础上对煤层顶底板破裂规律及岩体裂隙场分布规律进行了分析,提出了该工作面的防治水建议。
Yanmazhuang Coal Mine is a typical mine shaft with water inrush,coal and gas outburst danger. Water inrush has become a threat to the safe production of the coal mine. To prevent the hazard of water inrush, high precision BMS microseismie monitoring tech- nology was used for real-time water inrush risk monitoring,measuring points were designed on 27111 working face,52 effective seismic events were monitored, the laws of coal seam roof and floor crack, the distribUtion of fracture were analysed, too. Finally, water prevention countermeasures were proposed for 27111 working face.
