In order to avoid the above situation, it is very necessary to understand the general situation, classification, prominent features and mechanism of coal and gas outburst. Coal and gas outburst is a very complicated phenomenon, which has obvious signs before outburst, so the prediction and control method of coal and gas outburst is also introduced in this paper. In the forecast, it can be divided into two categories: the regional outburst risk prediction and the work face outburst risk prediction, the same, in terms of governance is also divided into two aspects of the regional conflict prevention measures and local prevention and control measures. Understanding of coal and gas outburst of the basic knowledge, combined with prediction and control methods, in the related area of mine were prominent pre processing, do a good job of protecting the safety of the underground work personnel and production equipment, prevent the occurrence of major accidents in production, dont let the tragedy happen again.
