摘要
以开滦集团唐山矿复杂地质条件为研究对象,针对深部不规则大孤岛工作面的冲击地压发生机理、冲击地压的合理预测和冲击地压的有效防治等问题开展研究,通过全面研究、观测、分析,确定了T1391孤岛工作面冲击地压危险区域,通过采取相关措施保障了T1391孤岛工作面实现高效安全开采。
Aimed at the complex geological condition of Tangshan Coal Mine, the formation mechanism of rock burst at deep irregular large island working face, the reliable prediction of rock burst and its effective prevention and control were researched. The danger area rock burst at T1391 island working face was determined after systematic and all-round investigation, monitoring and analysis. The high efficient safe production was ensured by taking corresponding measures.
