Study on Coal and Gas Outburst Status and Early Warning Technology in China Coal Mine

According to the coal and gas outburst status in China coal mine, the paper systematically analyzed the main eight laws of the coal and gas outburst 0CC urred.In order to meet the requirements of the mine safety production, the paper introduced the coal and gas outburst comprehensive early warning technology integrat ed with the geological survey, production, technology, dispatching, ventilation, outburst prevention, monitoring and control and the safety production information of each department.The study held the coal and gas outburst comprehensive early warning technology could be accurate to analyze, predict and early warn the dangerous hidd en dangers of the outburst prevention working face and the development tendency of the outburst danger degree at the front places.Thus the coal and gas outburst com prehensive early warning technology could be more accurate to predict the mine coal gas outburst danger and could be more accordance to the outburst prevention wor
