Mining rockburst prevention and treatment method

The invention discloses a mining rockburst prevention and treatment method, which belongs to the technical field of coal mining safety, and comprises the following steps: S1, drilling a vertical shaft; before a coal seam is mined, a vertical shaft is drilled beside an impact eliminating area of a dense rock stratum covering the coal seam, the vertical shaft is drilled into the dense rock stratum from the ground, and a vertical shaft sleeve is installed in the vertical shaft drilling process; s2, drilling a horizontal well; a horizontal well penetrating through the impact eliminating area is drilled at the tail end of the vertical shaft, a horizontal well casing pipe is installed, and the horizontal well casing pipe is communicated with the vertical shaft casing pipe; s3, multi-stage packing is carried out; packers are put down to pack the horizontal well casing in a segmented and step-by-step mode, and jet flow holes are formed in the horizontal well casing between the packers; and S4, fracturing stamping is
