根据刘店矿10煤层首采工作面底板岩层为高阻电性层的特点,采用电测深法进行探测,探测结果显示存在4个视电阻率低阻异常条带区,把其中幅值和范围相对较大、富水性和突水危险性较强的异常区作为重点防治水区。根据电测和钻探探查结论对1044工作面底板进行防治水工作,总结提出了“物探先行、疏水降压与底板加固相结合”的综合防治水途径。
The floor strata of first mining face of No.10 coal-bed of Liudian Mine is high resistivity. According to the characteristics, we explore by using electrical sounding method, exploration results show there are 4 bands that the low resistivity of apparent resistivity is abnormal. And the abnormal areas with large amplitude and extent, risk of water abundance and water inrush are the water control zones. According to the electric measuring and drilling conclusions, we make the water control for the floor strata of 1044 mining face. At last, it summaries the comprehensive water control ways of "geophysical prospecting goes ahead, combine dewatering and depressurization with bottom reinforcement".
