Comprehensive Outburst Prevention Technology in High Gas and High Stress Serious Outburst Thick Coal Seam

Taking FX005 working face as an example, through using comprehensive outburst prevention technology which combined gas geological pre-drainage tunnel advancing driving with punching, pressing, pumping (mining-coal bed and pressure relief area pumping), the measures for outburst prevention effect are greatly improved. The results show that the comprehensive outburst prevention and control technology can realize the comprehensive outburst prevention for high gas and high stress serious outburst seam working face, and eliminate the gas dynamic phenomenon.
