摘    要:为了确保矿井的安全生产,根据云盖山一矿22204工作面底板抽放巷瞬变电磁探测视电阻率值,预测在此次瞬变电磁探测范围内,探测出B级富水异常区2个,G级高阻畸变区3个,然后对综采工作面底板物探异常区检验孔进行施工设计,初步设计钻场5个,设计钻孔10个,钻探进尺1 160 m,来验证22204综采工作面瞬变电磁勘探报告探测的底板异常区,然后根据检验结果,对物探异常区附近进行注浆加固,封堵导水通道,加强隔水层强度,使含水层变为弱含水层或隔水层,确保工作面回采安全。

关 键 词:综采工作面  底板物探异常区  瞬变电磁勘探  检验孔  施工设计  效果评价

Abstract:In order to ensure the safe production of the mine,according to the apparent resistivity value of transient electromagnetic detection in the floor drainage roadway of No.22204 working face of Yungaishan No.1 Coal Mine.It was predicted that within the scope of this transient electromagnetic detection,two abnormal zones of B-grade water-rich and three abnormal zones of G-grade high resistivity were detected,and then the inspection holes of geophysical abnormal zones of the floor of fully-mechanized mining face were constructed.Five drilling sites,ten drilling holes and a drilling footage of 1 160 m were preliminarily designed to verify the abnormal area of floor detected by TEM exploration report in 22204 fully-mechanized mining face.According to the test results,grouting reinforcement was carried out near the abnormal area of geophysical prospecting,water conduction channel was blocked,strength of aquifer was strengthened,and aquifer became weak aquifer to ensure the safety of working face.
Keywords:  fully-mechanized working face   anomalous area of floor geophysical prospecting   transient electromagnetic exploration   inspection hole   construction design   effect evaluation
