特厚煤层冲击矿压机理及防治分析

Mechanism and Prevention Analysis of Impact Mining Pressure in Extra-thick Coal Seams

以具体工程实际为对象,对急倾斜特厚煤层回采作业中存在的冲击地压发生机理做了全面分析,并在此基础上提出了有针对性的冲击地压防治措施,同时对其应用效果进行了分析。结果表明,所采取的冲击矿压防治措施实现了对特厚煤层回采作业中冲击地压的有效防治,对提升矿井回采作业安全性有着积极意义。

Based on the actual engineering practice,this paper carried out a comprehensive analysis of the occurrence mechanism of impact ground pressure existing in the mining operation of steeply inclined and extra-thick coal seam,based on this,proposed targeted prevention and control measures of impact ground pressure and analyzed the application effects.The results show that the measures taken to control the impact mine pressure have effectively prevented the impact ground pressure on the mining of extrathick coal seams,and have positive significance for improving the safety of mine recovery operations.
