| 摘 要： | 文中介绍了利用地下全空间瞬变电磁(UWTEM)技术在某煤矿-250排水巷道掘进过程中进行的连续跟踪超前探测试验。根据初探结果,采用不共面同轴偶极观测方式时,UWTEM在巷道掘进头前方的有效探测范围约为70m,巷道每掘进50m进行一次跟踪探测。试验表明,利用该技术可以有效地超前预测煤矿巷道掘进头前方30~50m范围的富水异常,为及时采取水害治理措施提供依据

| Abstract: | Accurate prediction of geohazards far in advance of engineering works is a fundamental requirement in underground mining. Underground whole-space transient electromagnetic (UWTEM) method was tested at the driving face of a drift in a coal mine for detecting water-bearing zones ahead of tunneling. Having experimentally determined that the sounding depth is about 70m for a configuration of coaxial off-set loops in the drift, the UWTEM experiment was designed as such that measurements were made ahead of each t... |
