摘要
以3005综采工作面沿空掘巷为工作背景,在分析巷道底鼓破坏特征的基础上分析了巷道围岩强度及应力、护巷煤柱、支护方式对底鼓破坏的影响,给出了优化后的锚杆支护方案及底板处理方案。实践表明,巷道底鼓治理方案合理,巷道底鼓得到了有效改善,可以满足工作面安全生产要求。
Taking roadway driving along goaf in 3005 fully mechanized mining face as working background,based on the analysis of the failure characteristics of floor heave,the influence of surrounding rock strength and stress of roadway,coal pillar of roadway protection and support mode on floor heave failure is analyzed,and the optimized bolt support scheme and floor treatment scheme are given.The practice shows that the treatment scheme of roadway floor heave is reasonable and the roadway floor heave has been effectively improved,which can meet the requirements of working face safety production.
