Abstract：
The coal seam roof of Huojitu Mine is the burnt rock,which is the water impregnated aquifer,is dangerous to mine safety.The burnt rock distributed widely.The regularities of fracture development are vertically apparant,for example,the fractrues decrease upwards.The water abundance of the rock is controlled not only by structures,geographic and surface features,but also controlled by the recharge condition from other aquifer.The water quality of the rock can meet the drinking water standards of the state.Therefore,the water control combining dewatering and water supply is the effective way.
