Aiming at the problems of low-permeability outburst coal seam extraction and drilling, low punching efficiency and large personnel input,taking Cheji Mine as the test site, and using the methods of theoretical analysis and field test, the coal seam anti-reflection mechanism of the technology used for drilling and hydraulic Flushing is analyzed. The application test of the integrated intelligent equipment used for drilling and punching is carried out. The results show, the average drilling speed, punching speed, and drilling speed per meter of the integrated intelligent equipment used for drilling and hydraulic punching are 1.59 , 1.36 and 0.72 times that of ordinary drilling and hydraulic punching equipment. The overall operating efficiency and per capita operating efficiency of the single machine are respectively ordinary 1.3 and 3.9 times. The water jet broke through holes with a diameter of about 0.8~1m in the coal section of the borehole, providing space for coal deformation. Compared with ordinary through-layer drilling, the gas flow decay cycle of punching drilling is increased by 2 to 4 times.
