ON THE WATER BURSTING PASSAGE OF THE-210 m NORTHERN TUNNEL OF GUOJIAZHUANG COAL MINE IN FEICHENG COALFIELID
The water bursting yield of the -210m northern tunnel is up to 549.5m3/min in the Guojiazhuang coal mine.The total volume of the bursting mass is 16 518m3.There is many mass of collapse-column in the bursting mass.Based on features of water inrush and bursting mass,it shows that the water bursting passage is the fracture which is connected with the collapse-column.
