矿井物探技术在探测回采工作面导水陷落柱的应用

Application of Mine Geophysical Prospecting Technology in Detecting Water Diversion Collapse Column in Working Face

采用地质雷达与高密度电法探测相结合的综合物探方法,查明了马兰煤矿18306工作面回采中遇到的陷落柱空间形态及其导、含水性,并进行了钻探验证,结果表明综合物探方法能够较准确地探查陷落柱的基本形态及导、含水特性,有效圈定富水区域,为后期治理提供了地质依据,保证了马兰煤矿18306工作面的安全回采,对类似地质情况下的陷落柱探查具有一定的借鉴意义。

By using the integrated geophysical exploration method combining ground penetrating radar with high density electrical method,the spatial form of collapse column,its conductivity and water content encountered in coal winning of 18306 working face in Malan Coal Mine were identified and verified by drilling.Results showed that this integrated geophysical exploration method can more accurately explore the basic form,conductivity and water-bearing characteristics of subsidence columns,effectively delineate water-rich areas,and provide geological basis for later treatment,it also has ensured the safe mining of 18306 working face in Malan Mine,and has certain reference significance for the exploration of subsidence column under similar geological conditions.
