Abstract: Based on three factors of coal and gas outburst (gas, ground stress, physical and mechanical property of coal) can be integrated to control the reflection of coal and gas outburst of geologic body. For the prediction, early warning and prevention work of coal and gas outburst, this study proposes a method from coal and gas outburst master control geologic body. The master control geologic body is analyzed from tectogenesis, sedimentary sequence and burial and hydrocarbon-generation histories three aspects. By the application analysis in the plate, mining area and coal mine three levels, it can solve some of the coal mine area forecast, coal seam gas deposit appraisal work.
