Abstract: Rock-bursting is a special underground pressure behavior in deep mining in China currently and it intimidates seriously the safe mining.Aimed at the steeply inclined coal seam of Datai Mine,practicable prevention measures are put forward and better effective is obtained.These measures include the layout of bores,selection of water-pouring equipments and confirmation of water-pouring parameters,et al.The measures that should be adopted in water-pouring for coal seam with worse penetrability,hygroscopicity and wettability are expounded.Practice shows that water-pouring with high pressure for this kind of coal seam can prevent rock-bursting and ensure safe mining.
