| 摘 要： | 为了解决煤矿井下独头巷道掘进过程中突发事故的预测和预防问题,笔者提出了一种在井下应用的超前探测的方法——瑞利波勘探法,并简要介绍了瑞利波勘探的基本原理。利用瑞利波对分层介质具有频散的这种特性,对巷道掘进前方的断层、破碎带、岩灌、陷落柱等复杂地质构造进行了超前探测。根据对现场采集的数据进行处理和分析,得出的结论与实际打钻结果相近,证明了利用瑞利波探测技术能进行有效的超前探测,解决了一些掘进前方的地质问题。它与打钻配合使用,进一步加强了对巷道前方的地质预报,是一种有效的辅助手段。

| Abstract: | During coal production,accidents of coal and gas outburst happen frequently in china,which has become the top killer of miners.Coal and gas outburst is the result of various factors such as ground stress,gas,and coal body structure,of which the geological factor plays a leading role.Complex regional geological structures are usually of the gas disaster-prone areas.The position where coal and gas outburst often happens is usullrally related to the destruction of the geological structures,such as secondary fa... |
