井上下综合物探技术在益东煤矿工作面安全开采中的应用（10月增刊）

益东煤矿为了掌握工作面水文地质条件及工作面内冲刷带等地质异常体,探讨出了一套行之有效的工作面井上下综合物探手段：在工作面开采之前采取地面瞬变电磁法对覆岩富水性进行探查,同时根据工作面两巷掘进揭露情况,选择采用槽波、井下瞬变电磁和无线电波透视法对工作面构造、冲刷带异常区和顶板覆岩富水性进行综合探测。探测结果为煤矿的安全生产提供了地质保障并提高了生产效率。

Application of comprehensive geophysical exploration technology above and below the well in safe mining of Yidong Coal Mine working face

In order to master the hydrogeological conditions of the working face and the geological abnormal bodies such as the scouring zone in the working face, Yidong Coal Mine has discussed a set of effective comprehensive geophysical exploration methods for the upper and lower wells of the working face: Before the mining of the working face, the ground transient electromagnetic method is adopted to explore the water abundance of the overburden. At the same time, according to the excavation exposure of the two roadways of the working face, the trough wave, underground transient electromagnetic and radio wave perspective methods are selected to comprehensively detect the working face structure, the abnormal area of the scour zone and the water abundance of the roof overburden. The detection results provide geological guarantee for the safe production of the coal mine and improve the production efficiency.
