This paper introduces the first application of working face pregrouting method as the prevention measure in the high outburst mine where the gas pressure is up to 3.1 MPa. The gas channels in the coal seam around the wellbore are closed, and smoothly getting through the outburst coal seam. Good results have been achieved in the construction. The application of this technology in Shaqu coal mine south wind well vertical shaft coal uncovering has obtained safe, rapid, economic and efficient results.
