10-201工作面充水因素分析与防治水措施

Analysis of Water filling Factor and Water Control Measures at 10-201 Working Face

木瓜煤矿10-201工作面充水水源主要为顶板灰岩裂隙水,工作面初采初放期间预计最大涌水量50 m^(3)/h,回采期间正常涌水量为20~30 m^(3)/h。综合采用瞬变电磁探测、无线电波坑道透视、探测钻孔进行了工作面水文地质探测与验证。探测结果显示,10-201工作面回采区域内无其它不良水体及地质异常体,为工作面安全开采提供了依据。

Aiming at the water filling source of roof limestone fissure water at 10-201 working face of Mugua Colliery with the estimated maximum water inflow of 50 m^(3)/h during primary mining and caving,and the normal mining water inflow of 20~30 m^(3)/h during stoping,the paper presents the comprehensive application of TEM detection,radio wave tunnel perspective and drilling in hydrogeological detection and verification,whose results show that there are no unfavorable water body and geologic abnormal body in the mining area of 201 working face,providing a basis for safety mining.
