基于大断层影响下的冲击地压防冲研究

The Study of Impact Ground Pressure and Impact Prevention under the Influence of Large Faults

本文以汾西矿业双柳煤矿4038工作面为工程背景,通过探究其矿井深部大断层与开采工作面的位置关系和应力分析,并通过RFPA数值模拟软件判断其发生冲击地压的可能参数,运用钻屑法指标来判定超前工作面支承应力的分布,及时对工作面采动过程的冲击危险预判,保证了矿井安全生产。

Taking 4038 working face, Shuangliu Coal Mine, Fenxi Mining, as the engineering background, through exploring the deep large fault in the mine and the position relationship and stress analysis of mining work face, and through the RFPA numerical simulation software, we determine the occurrence of percussive ground pressure parameters. By using the method of drilling cuttings indicators, we determine bearing stress distribution of the advance face, and anticipate in a timely manner the impact of the mining process risk. The above method is used to explore the mechanism of impact pressure on deep mines with large faults and ensure the safe production of mine.
