摘要
复杂地质条件下,煤矿冲击地压问题严重威胁矿井安全生产.通过系统分析煤层赋存环境、地质构造特征等因素对冲击地压的影响,构建一个综合性的冲击地压危险性评估模型.基于此模型,提出优化采矿方法、加强巷道支护、实施预防性卸压等防治策略.研究结果表明,采用所提出的控制技术,能够显著降低复杂地质条件下煤矿冲击地压的发生频率和强度.相关结论为提高矿井安全生产水平提供了重要的技术支撑,同时为深部煤矿开采中的地压控制提供了新的思路和方法.
Abstract
The problem of coal mine rockburst under complex geological conditions poses a serious threat to mine safety production.By systematically analyzing the impact of factors such as coal seam occurrence environment and geological structure characteristics on rockburst,a comprehensive rockburst risk assessment model is constructed.Based on this model,propose prevention and control strategies such as optimizing mining methods,strengthening roadway support,and implementing preventive pressure relief.The research results indicate that the proposed control technology can significantly reduce the frequency and intensity of coal mine rockburst under complex geological conditions.The relevant conclusions provide important technical support for improving the safety production level of mines,and at the same time provide new ideas and methods for ground pressure control in deep coal mining.
