巷道水害防治中瞬变电磁超前探测应用分析

Application Analysis of Transient Electromagnetic Advanced Detection in Roadway Water Disaster Prevention

巷道掘进安全作为直接影响矿井生产综合效益的重要环节,确保其作业质量至关重要,而水害隐患作为一种不易被发现的安全隐患,一直是威胁井下掘进安全的主要问题。以此为着手点,针对巷道水害防治中瞬变电磁超前探测技术的应用开展分析,结合具体工程实际,在分析瞬变电磁法作业原理的基础上,利用其对掘进巷道前方区域进行探测,确定出富水异常区域,进而制订有针对性的超前钻孔疏排水方案,以实现富水异常区域积水的有效外排,提升矿井的作业安全。

Roadway driving safety is an important part that directly affects the comprehensive benefits of mine production,ensuring the quality of its operations is essential. As a hidden danger difficult to be discovered, water hazard has always been a major problem threatening the safety of underground driving. Taking this as the starting point, this paper analyzed the application of transient electromagnetic advanced detection technology in the prevention and control of roadway water damage. Combining the actual engineering practice, based on the analysis of the operation principle of transient electromagnetic method, it was used to detect the area in front of the roadway and determine the water-rich anomaly area, and the advanced drilling and drainage system was developed in order to achieve effective efflux of water accumulation in the water-rich anomaly area and improve the operation safety of the mine.
