摘要
以蒙东矿区敏东一矿13S101工作面为例,综合应用地面瞬变电磁和井下直流电法,对工作面顶板松软砂岩含水层的富水性进行探测,叠加圈定了疑似富水区范围。井下钻探结果表明,"地面瞬变电磁+井下直流电法"的综合物探技术能提高砂岩含水层富水性探测的精度。
Put the 13S101 workface of Mindong No.1 coal mine in eastern Inner-mongolia as example, the water-rich extent of roof loosening sandstone aquifier in 13S101 was prospected with comprehensive application of surface transient electromagnetic and underground DC method,and the range of water-rich area were delineated using multiple superposition. The prospecting accuracy of this comprehensive geophysical method was proved more accurate than before by underground borehole drilling.
