避免采矿诱发冲击地压成灾的卸压洞法

The Method of Pressure Relief Cave in Avoiding Rock-Burst Disaster Induced by Mining

就在采矿、掘进等岩土工程活动中诱发冲击地压特点及其破坏特征进行了论述。提出了一种经济、有效而可行的防治冲击 地压成灾的卸压洞法。同时又从岩石力学系统稳定性角度,对其进行了理论分析。该法从本质上是在矿山采掘活动中以人为定点开挖 卸压洞来弱化煤体,使由采掘诱发的冲击地压在预定点发生,释放其周围系统中的大部分能量。即在人为预定点放灾而达到控制或防 治冲击地压灾害的目的。

In this article, writers put forward the method of pressure relief cave in avoiding rock-burst disaster induced by mining. The emphasis of the method is that we can weaken coal body factitiously at some given places and ensure that rock-burst will occur at those places. While the rock-burst occurred at those given places, the excrescent energy of the system will be released, thus achieving the goal of prevention and cure of rock-burst disaster.
