复杂应力环境留窄煤柱沿空掘巷及围岩控制技术
Gateway driving along goaf and surrounding rock control technology for Narrow coal pillar left under complex stress state
通过分析余吾煤业原有的工作面巷道布置方式存在的不足，提出采用留窄煤柱沿空掘巷技术进行优化，从而提高采煤率，并使得巷道处于采空区侧向低应力区，显著改善了巷道维护状况。结合余吾煤业S1202工作面生产地质条件，采用理论分析与数值模拟的方法分析不同窄煤柱宽度下围岩变形情况，从而最终确定合理的窄煤柱宽度及巷道支护技术，为实现矿井高产高效提供了理论依据。
By analyzing shortcomings of original gateway layout in Tunliu Mine,puts forward driving along goaf optimized,could improve the mining rate,and make Make roadway in low stress area of gob area,improved significantly roadway maintenance condition.Combining with the production geology conditions of S1202 inTunliu Mine,according to the theoretical analysis and numerical simulation,the surrounding rock deformation of different pillar width was analysed reasonably,a reasonable width of narrow coal pillar and roadway supporting technology was determined,successfully creates good condition for high-yield and high-efficiency.
