摘要
为了解决近距离煤层近距离煤层开采难题,通过沙坪煤矿8~#煤近距离开采生产实践,分析了1811工作面巷道掘进、1808工作面回采中存在的问题,提出了近距离煤层开采顶板管理措施,总结出近距离煤层开采对应措施,可对今后近距离煤层开采研究提供参考价值。
In order to solve the problem of close coal seam mining in close distance coal seam,through the practice of 8~# coal seam close-distance mining in Shaping Coal Mine,the problems existing in the roadway excavation of the 1811 working face and the mining of the 1808 working face were analyzed,and the roof management measures of close-distance coal seam mining was proposed,and the corresponding measures for close-distance coal seam mining are summarized,which can provide reference value for future research on close-distance coal seam mining.
