The invention discloses an execution system of gas tunnel outburst prevention comprehensive measures; regional forecast of a coal layer or a rock layer of a tunnel within the range of 60M is firstly carried out along the trend of the tunnel, and forecast results are divided into a non-hazardous area, a threatening area and a hazardous area; the treatment is respectively carried out on the hazardous area and the threatening area: outburst prevention measures are taken on hazardous surfaces obtained by working surface forecast in the threatening area and the hazardous area to eliminate or reduce the dangers; the effects of the outburst prevention measures are checked; when the effect check result of the outburst prevention measures does not achieve the desired effects or is ineffective, theoutburst prevention measures are taken again; when the effect check result of the outburst prevention measures is in the control range, the excavation work is carried out under the premise of adopting safety measures. The invention discloses the execution system of comprehensive outburst prevention techniques, and the execution system comprises comprehensive matching applications of forecast and prediction of outburst, outburst prevention technical measures, measure effect check, safety measures and other aspects, thereby realizing comprehensive and effective gas outburst prevention.
