摘要
对寺家庄煤矿软岩地质条件及巷道开采后相应矿压显现特性的研究,有针对性地提出了软岩巷道掘进支护形式和支护对策。同时针对生产现场的实况的变化进行不断优化完善,逐渐形成了寺家庄煤矿软岩巷道掘进综合支护技术,有效保障了该煤矿的生产安全。
Based on the study of soft rock geological conditions and corresponding mine pressure appearance characteristics after roadway mining in Sijiazhuang Coal Mine,the supporting forms and countermeasures of soft rock roadway excavation are put forward.At the same time,according to the actual changes of the production site,the comprehensive support technology of soft rock roadway excavation in Sijiazhuang Coal Mine has been gradually formed,which effectively ensures the production safety of the coal mine.
