摘要
为解决采掘接替紧张及资源浪费问题,新源煤矿依据工作面生产地质条件,采用高水速凝材料巷旁充填,对1219工作面顺槽进行沿空留巷,取得较好支护效果,并解决了采掘衔接和资源的有效利用问题。
To solve mining-excavation relay strain and resource waste,gob-side entry retaining was used in No.1219 working face in Xinyuan Mine,side-filled with high-water-content and quick-setting materials,on the basis of the geological condition,which achieved ideal supporting effect and solved the problems like extracting joining and effective resource utilization.
