摘要
根据峪煌煤业矿井水文地质资料和掌握的邻近老空区积水资料,采取物探先行,钻探验证,并结合化探跟进多项探测手段,对2号煤层水文地质类型进行了综合评价,探讨了2号煤层的防治水措施,确保了工作面的安全回采。
According to the waterlogging documents at neighboring goafs and the hydrogeological documents of Yu-huang mine,the paper adopts the geophysical prospecting firstly,improves by the drilling,undertakes the comprehensive evaluation of the hydrogeological types of No. 2 coal stratum by combining with various detection measures,and explores the water protection measures of the stratum,so as to ensure the safety of the working surface.
