Study Status and Prospects for Regional Prediction Methods of Coal and Gas Outburst in China

The paper summarized the existing regional prediction methods of coal and gas outburst in China coal mines,emphatically introduced the index method,geology method,geophysical prospecting method and mathematical physics method,briefly analyzed the main existing problems for all kinds of methods,forecasted the development trend about regional prediction of outburst. The author pointed out that the progress trend of regional prediction about coal and gas outburst in our county were: constantly improved the existing methods of gas outburst regional prediction,improved the adaptability and effectiveness in different geological conditions; strengthened research on basic theory of gas outburst,made full use of various modern theory and technology,comprehensive consider the basic factors of ground stress,gas and coal properties that determined the danger of gas outburst,building- up comprehensive methodology system of outburst based on multiple factor analysis; actively explored and researched on disaster evaluation and controlling factors of outburst in deep mines put forward the methods of regional prediction for the outburst which applied to coal mining in deep mine.
