摘要
为准确探测掘进工作面前方的隐伏含水构造,基于五里堠煤矿1130回风顺槽掘进工作面实际地质条件,提出了远距离超前声波法及矿井直流电法相结合的综合物探技术。结果表明:该综合物探技术较准确地预测了掘进面前方隐伏断层的位置及规模,与实际揭露位置仅相差0.4~0.9 m,可为煤矿井下巷道的安全高效掘进提供依据。
In order to accurately detect the concealed water-bearing structure in front of the driving working face,based on the actual geological conditions of the 1130 return air channel driving working face in Wulihou Coal Mine,a comprehensive geophysical prospecting technique combining long-distance advanced acoustic method and mine direct current method is put forward.The results show that the comprehensive geophysical technique can accurately predict the location and scale of the hidden fault in front of the driving working face,which is only 0.4-0.9 m different from the actual exposed position,which can provide a basis for safe and efficient driving of underground roadway in coal mine.
