摘　　要：针对煤矿井下水力压裂增透技术有效范围不明确、容易产生压裂空白带或诱导煤与瓦斯突出等问题,提出基于瞬变电磁法的煤矿井下水力压裂有效范围监测方法,探讨瞬变电磁法监测水力压裂范围原理,建立了水力压裂后煤岩体含水率异常体位置深度模型,优化瞬变电磁测线(点)布设工艺,并在新元煤矿南区31009辅助进风巷进行工业性试验。Aiming at the problem that the scope of hydraulic fracturing technology in coal mines is not clear,resulting in fracturing gaps or induced coal and gas outbursts are prone to occur,a method for monitoring the effective range of hydraulic fracturing in coal mines based on transient electromagnetic method is put forward,and the principle of transient electromagnetic method for monitoring hydraulic fracturing range is explored.Established the location depth model of the abnormal moisture content of coal rock after hydraulic fracturing and optimization of transient electromagnetic line（spot） deployment process.At last the industrial pilot test was conducted at the auxiliary air inlet in the 310009 roadways of south district in Xinyuan coal mine.
