摘要
南一采区有一定的充水规律,也存在着矿井水害问题。重点对含水层、"天窗"等水文地质条件复杂的地区提出安全开采方案。-300m以上分区段进行垮落法或充填法开采。-300m以下原则上可进行垮落法开采,右片回采可用垮落法,左片回采原则上采用充填法,以解放煤炭资源。
This paper focuses on the aquifer, " skylights "and other areas of complex hydrogeological conditions,Against how to conduct safe mining of coal resources liberation,-300 Meters above the partition segment caving mining method or filling method,-300 meters below may be caving mining method, in principle, the right pieces available caving mining method, using the left-chip mining backfill principles., made some recommendations.
