摘要
为改善沿空掘巷维护状况、提高煤柱回收率,通过数值模拟分析,研究了综放沿空掘巷窄煤柱的稳定性以及合理的煤柱宽度,为在同类条件下确定合理的沿空掘巷窄煤柱宽度提供了借鉴。
In order to improve the maintenance situation in the driving roadway along goaf and the recovery rate of coal pillars,the narrow pillars stability and reasonable pillar width of the driving roadway along goaf are studied by numerical simulation,a reference is provided to determine a reasonable width of narrow coal pillars in driving roadway along goaf.
