In order to solve the problem that may cause hurricane would, blowing down support, Chengzhuang Mine of Jincheng Anthracite Coal Mining Group was taken as example, its No. 3 coal seam with hard roof and difficult falling, blasting forced caving technology was adopted in fully mechanized working face, hole arrangement, hole charge demands, explosion requirement were studied, forced explosion measure was adopted to minimize main roof first weighting interval, which simplified working face recovery technology, realized safe caving and ensured the safe production.
