采矿地球物理方法对顶板大面积来压的预测

Large Area of Roof Pressure Prediction by Mining Geophysical Methods

顶板大面积来压是严重威胁矿井安全生产的动力灾害。随着矿井开采情况越来越复杂,顶板大面积来压所带来的危险和危害也越来越严重。介绍了电磁辐射、微震法、声波法预测顶板大面积来压,为有顶板大面积来压危险的矿井的决策者和工程技术人员提供一些参考。

The large area of roof pressure is a dynamic disaster which threats mine security seriously.As the mine exploration has become increasingly complex,the dangers and hazards brought by the large area of roof pressure are getting worse.This article mainly describes the electromagnetic radiation,micro-seism method,acoustic method to predict a large area of roof pressure,in order to provide some reference to the decision-makers and engineers who may suffer the large area of roof pressure.
