结合在西部某矿井下和地面瞬变电磁探测的具体工作,阐述了瞬变电磁法在煤矿井下的使用方法,探测正在掘进的运输大巷和回风大巷的侧帮、掌子面等前方80 m左右区域的富水异常区分布,此外,在运输大巷、回风大巷附近区域的地面进行了瞬变电磁探测,精细查明煤矿富水异常区,推断导含水地质构造等。
Combined with the specific work of transient electromagnetic detection under a certain mine in the west and on the ground, the method of using transient electromagnetic method in coal mine is expounded, and the front side of front and back sides of transportation lanes and return lanes being driven are probed In addition, transient electromagnetic surveys were conducted on the ground near the transportation lanes and return lanes to finely identify the anomalous water-rich areas in coal mines and to infer the water-bearing geological structures.
