Abstract: According to the features of the mine pressure bumping frequency occurred during the mining and driving period, the high pressure water jet coal cutting and pressure releasing technology was applied to prevent and control the mine pressure bumping.In combination with the actual conditions, the FLAC2D numerical sim ulation software was applied to simulate nine group orthogonal experiments and the results showed that when a construction plan with a borehole space of 2 m and a b orehole diameter of 300 mm was applied, the coal body would have a pressure releasing effect.The site application results showed that after the high pressure water jet was applied to cut the borehole, the electromagnetic radiation value was about 20 mV in average and was far lower than the electromagnetic radiation value before the borehole cut.The condition of the sos microseismic monitoring and measuring also reflected that the daily total energy value was small generally during the borehole C ut period and no high energy accident occurred.
