摘要
探查石墨矿巷道迎头前方区域富水情况,提前做好疏放水工作,可以有效减少突水事故的发生。文中在综合分析各种物探手段的基础上,选用在探查低阻异常方面具有优势、同时对水体敏感的瞬变电磁法进行超前探测,并在某石墨矿使用该方法进行了实测。后期经矿方掘进验证,探测成果与实际情况相符,可信度高。因此瞬变电磁超前探可作为防治水工作的可靠方法。
Exploring the water-rich situation in the front area of the roadway in graphite mine and doing well the drainage work in advance can effectively reduce the occurrence of water inrush accidents.On the basis of comprehensive analysis of various geophysical prospecting methods,the transient electromagnetic method,which has advantage in detecting low resistivity anomalies and is sensitive to water body,was used in a graphite mine for advanced detection.The verification of mine excavation shows that the detection results are consistent with the actual situation and have high reliability.Therefore,transient electromagnetic advanced exploration can be used as a reliable method for water control.
