The invention relates to a method for releasing pressure and removing danger of
rock burst. The effects of releasing pressure and removing danger of
rock burst and ensuring the safety of a
coal mine can be effectively realized. The method comprises the following steps of: releasing pressure and
bursting a
coal bed; because of higher inner stress in the
coal bed, drilling a roadway wall to form a
free space, so that the stress is re-distributed; drilling to enable pressure and water solution to enter a coal body and increase
water content;
bursting a top plate of the coal
bed;
bursting a bottom plate of the coal bed; through
high pressure, filling
fracturing fluid into cracks and slots which are formed in the coal body before fracturing and after fracturing; expanding, extending and dredging the cracks; increasing the slots of the coal bed; changing the magnitude and the direction of the stress on the coal body; transmitting the stress to the deep part of a coal-rock
mass; and selecting the safe coal bed or coal body to
exploit, wherein after a goaf area and a natural caving arch are formed, an unloading effect is achieved, the
rock burst and roof collapse are prevented or relieved. The method is stable and reliable, good in pressure-releasing and danger-removing effects, and high in economic and
social benefits, prevention and control on the rock burst are realized, and the safe production of the coal mine is effectively protected.
