摘要

Based on the gas-geology rules of Chinese coalmines, the outburst accidents are characterized and the main reasons are found out on serious coal and gas outbursts in China. The development history of coal and gas outburst prevention and control are briefly introduced, and various related technologies and management system for outburst prevention were discussed in detail. The problems and development trends of outburst prevention and control in China were put forward in this paper. The results show that the geological conditions and mining conditions are highly complicated compared to other countries; coal seams in China have characteristics of high ground stress, high gas content and gas pressure, low strength and permeability. Current outburst prevention technology is mainly a combination of both regional and local measures. Regional comprehensive outburst-prevention measures include four integrated parts, prediction of the regional outburst danger, regional outburst prevention measures, validation of the measures and onsite verification check. Local comprehensive outburst-prevention measures include prediction of working face outburst danger, working face outburst prevention measures, validation check, and safety protection. With the goal to totally eliminate all outburst accidents effectively and efficiently, supportive policies, both financial and technologic, are necessary to lead and guide coal mining enterprises to manage outburst mine actively, plan production activity reasonably and utilize new technologies and equipments eagerly.
