Abstract
In order to improve the recovery rate of coal resources, Xin'an coal company mine NO. 3311 materials lane along NO. 3309 goaf, is setting the 4m small coal pillar. After tunneling 200m, it is found that the roadway pressure is obvious. The original support system is not suitable for roadway support along the goaf. In view of the actual situation of the gob side entry support, the original support scheme is optimized.关键词
