摘要
为探测古城煤矿N1302工作面底板富水情况,采用并行电法对工作面底板进行探测,并由此进行三维电阻率联合反演。结果表明:N1302工作面胶带顺槽侧底板下方10〜60 m处存在低阻异常区域,含水层为弱富水性,为工作面水害防治提供了可靠依据,保证了工作面安全回采。
To detect the water yield in the floor of N1302 working face in Gucheng Colliery,the author proposes the parallel electrical method and the joint inversion of three-dimensional resistivity,whose results show that there is a low-resistance abnormal area 10~60 m below the bottom of the groove side with weak water-yield aquifer,providing a reliable basis for the prevention and control of water hazards and ensuring the safety mining at working face.
