摘　　要：近年来,水力压裂技术已在全国煤矿逐步推广应用,该技术能增加松软煤层透气性,特别在条带掘进、石门揭煤等工程实践当中增透效果显著,提高了瓦斯抽采量并有效防止了瓦斯灾害的发生。为探明高压水力压裂影响区域,优化设计水力压裂钻孔间距、压力、水量等工艺参数,在石壕煤矿开展了基于微地震监测和瞬变电磁探测技术的水力压裂影响区域探测试验。试验结果表明,微地震监测和瞬变电磁探测均能有效帮助矿井掌握水力压裂影响区域,为矿井水力压裂设计及工艺优化提供参考。In recent years,hydraulic fracturing technology has been gradually promoted and applied in coal mines across the country.This technology has significantly improved the permeability of soft coal seams,especially in engineering practices such as strip excavation and coal uncovering by cross-cut,which has improved the amount of gas extraction and prevented the occurrence of gas disasters effectively.In order to find out the affected area of high pressure hydraulic fracturing and optimize the design of hydraulic fracturing drilling hole spacing,pressure,water quantity and other technological parameters,a hydraulic fracturing affected area detection test based on microseismic monitoring and transient electromagnetic detection technology was carried out in Shihao Coal Mine.The test results show that both microseismic monitoring and transient electromagnetic detection can effectively help the mine master the affected area of hydraulic fracturing,and provide references for the design and process optimization of mine hydraulic fracturing.
