摘要
为保障坤达煤业3207运输顺槽顺利掘进通过老空水区域,根据巷道地质及水文情况,确定使用瞬变电磁探测技术进行老空水位置的探测,并根据瞬变电磁响应特征进行瞬变电磁探测方案的设计。探测结果表明,巷道迎头老空水区域主要在前方60~100 m,右侧帮老空水区域主要在65~105 m,通过设计放水钻孔,确保了巷道顺利掘进通过老空水区域。
In order to ensure the smooth excavation of 3207 transportation roadway in Kunda Coal Industry through the goaf area,according to the geological and hydrological conditions of the roadway,transient electromagnetic detection technology was adopted to detect the location of old hollow water,and the transient electromagnetic detection scheme according to the characteristics of transient electromagnetic response was designed.The detection results showed that the goaf water area was mainly 60-100m,and the old hollow water area at the right gang is mainly in the range of 65~105 m ahead.By designing the water release borehole,the roadway can be mined through the goaf water area smoothly.
