Based on analyzing 42216-1 and 42211 working face of Yujialiang Mine, the mine boundary edge region and alleys or panels can't recycle fully mechanized working face arrangement and coal pillar resources, mainly adopted four linear brackets room recycling process for caving method, but in the bedrock of extraction of the region more than 40 m because of basic roof caving, periodic weighting had obvious difference with thin bedrock section stoping, stent crushing caused in the process of mining, the situation of the coal buried, so the coal pillar of concentrated lane arrangement, this section between the coal pillars, mining method, stoping sequence and roof management method to improve the mine recovery rate.
