综合物探技术在王晁煤矿12207工作面的应用

Application of comprehensive geophysical prospecting technology in 12207 working face of Wangchao Mine

井田在开采设计前,需要准确掌握煤层水文地质情况。以王晁煤矿12207工作面为工程背景,利用三维地震法与瞬变电磁勘测法相结合的综合物探方法对12207工作面煤层区域进行了勘测,确定了积水采空区以及断层范围及位置,煤岩层走向等地质情况,并对部分区域勘测结果进行了打钻验证,验证结果与勘测结果一致,表明了综合物探结果准确可靠,为采区的开采设计以及回采提供了安全保障。

Before mining design, the mine field needs to accurately grasp the hydrogeology of coal seam. The 12207 working face of Wangchao Mine was taken as the engineering background, a comprehensive geophysical prospecting method combining 3D seismic method and transient electromagnetic survey method were used to survey the coal seam area of the 12207 working face, and the waterlogged goaf area and fault range and location were determined. The geological conditions such as the stratum and the drilling results of some areas were verified by drilling. The verification results were consistent with the survey results, indicating that the comprehensive geophysical prospecting results were accurate and reliable, which provided safety guarantee for mining design and mining in the mining area.
