Abstract: Taking the gob side return airway of 705 working face in Baojishan Coal Mine as the engineering background, through the research methods of field investigation, theoretical analysis, electron microscope scanning, numerical simulation and field industrial test, the technology of drilling cutting and punching with water jet to prevent rock burst was studied.The results show that:the water jet mainly drills and cuts the hole wall by the basic section water jet, and the coal cracks are very developed in the plastic zone around the hole wall after punching; the drill bit moves continuously along the axial direction of the borehole during the punching process, and the columnar punching space formed can achieve the effect of pressure relief and antireflection for coal mass, and the "double peak value" stress curve with peak value of "low inside and high outside" will be formed again in coal mass; when the punching diameter is 420 mm, the center distance between two adjacent boreholes is 5 m, and the length of punching section is 10 m, the effect of pressure relief and antireflection is the best. During the field industrial test, the monitoring data of electromagnetic radiation and gas flow attenuation verify the effectiveness and feasibility of this technology.
