摘要
针对矿岩软破、稳定性差异较大的情况,综合考虑矿岩性质、应力环境、巷道使用功能、巷道服务年限4个主要影响巷道支护形式的因素,运用多指标综合分类法对巷道进行支护分级,并制定相应的支护方案。该分级方法在夜场坪钼矿巷道支护中得到应用,结果表明,巷道支护分级能快速确定各采场工程体所需要的相应支护方案,并能保证巷道的稳定性。
In view of the situation that the different ore rock stability of soft and broken,support classification is carried out for underground workings,taken into comprehensive account the ore-rock property,rock stress environment,service function and service time 4 main influencing factors of roadway supporting form.Based on multi index comprehensive classification method,the corresponding supporting scheme is formulated.The classification method has been adopted in roadway support of Yechangping Molybdenum Mine.Application results indicate that the classification of roadway support can quickly determine the corresponding support scheme that the stope engineering body needs and guarantee the stabilization of roadway.
