摘要
结合井下巷道的实际情况,利用瞬变电磁法对程楼断层的含(富)水性进行探测,并利用大型通用有限元软件Ansys进行室内资料处理解释。结果显示,程楼断层在正常区段含(富)水性弱,只有在与北北东向-近南北向断层的交汇部位有一定的含(富)水性。同时,以程楼断层为例,利用瞬变电磁对煤矿井下探放水试验,验证了瞬变电磁法在煤矿井下断层含(富)水性探测中的有效性,为查明井下过断层矿井水害的发育位置,安排井下探放水工作提供依据。
Combined with the actual situation of mine roadway,the aquosity(water yield property)of Chenglou fault was detected through transient electromagnetic method using processing and interpretation data and large generalpurpose finite element software Ansys.The results show that the low aquosity(water yield property)of Chenglou fault in the normal segment and some aquosity(water yield property)appear only at the intersection of the NEE and near the north-south trending faults.Chenglou fault was given coal mine drainage exploration test to verify the effectiveness of transient electromagnetic method in the detection of aquosity(water yield property)of the coal mine fault.This research helps the identification of coal mine water damage over the development of fault location and provides foundation of the arrangement of coal mine exploration and discharging work.
