摘要
利用RFPA岩石破断过程分析系统软件分析了大倾角煤层开采过程中的顶板变形及破坏规律和工作面矿压显现规律,对煤矿大倾角煤层的安全开采提供了重要的保证。
It is analyzed in this paper that the law of out of shape of roof and the ore pressing and appearing in the exploiting course of large inclination coal seam by RFPA. It has offered the important assurance to the security exploitation of the large inclination coal seam.
