Abstract

Based on the geological conditions and equipments characteristics of Ruilong coal mine,introduce the recovery increasing methods of sublevel caving coal working face from the aspects of adjusting drawing sequence and interval,installing coal collector,strengthening the recovery of tip sublevel caving coal and the like.The results show that,after transformation,the recovery of sublevel caving coal is more than 85 percent,it provides reference for similar coal mines.
