随掘震电联合超前探测技术在断层探测中的应用

Application of Combined Seismic and Electrical Advanced Detection Technology during Tunneling in Fault Detection

摘要: 随着煤矿开采向深部延伸，隐伏断层、破碎带及异常含水体等不良地质体成为制约巷道安全高效掘进的重要因素。本研究针对传统单一方法在断层识别中分辨率不足、多解性强的问题，采用随掘震电联合探测技术，对巷道前方的断层构建进行精准识别。现场试验表明，该技术在钱营孜矿瓦斯鉴定巷道成功超前50 m识别落差2.5 m断层。随掘震电联合超前探测技术为巷道智能掘进提供了可靠的地质保障。

Abstract: As coal mining progresses deeper, adverse geological bodies such as concealed faults, fracture zones, and abnormal water-bearing bodies have become important factors restricting the safe and efficient tunneling of roadways. To address the problems of insufficient resolution and strong non-uniqueness of traditional single methods in fault identification, this study uses the seismic-electric combined detection technology while tunneling to accurately identify the fault structure in front of the roadway. Field tests show that this technology successfully identified a fault with a throw of 2.5 m 50 m ahead in the gas identification roadway of Qianyingzi Mine. The seismic-electric combined advanced detection technology while tunneling provides reliable geological support for the intelligent tunneling of roadways.
