The Technology Practice of Using Water Injection to Prevent and Control the Rock Burst in Emerging Mining Thin Coal Seam

In view of the frequent percussive ground pressure in the stage of deep mining in emerging mining thin coal seam,through the summary of the occurred mechanism of rock bursts,on the basis of this,the paper studies the principle of coal seam water injection prevention and control of percussive ground pressure,in combination with the practical situation of coal mine 41601 face impact ground pressure,through the coal sample water absorption test comprehensive evaluation to get coal seam water injection soften coal,it reduced the possibility of danger and rationality,puts forward using the coal seam water injection to prevent and control rock bursts,which has made significant effect,and has important guiding significance.
