Abstract: The paper utilizes fuzzy cluster analysis method to carry on comprehensive evaluation of coal and gas outburst hazard degree for Guizhou Jinjia Mine close distance outburst coal bed group, and analyzes typical characters and the coal and gas outburst influencing factor, and then determines the gas pressure and content, diffuse the initial velocity, consistent coefficient, coal volume density, coal seam thickness and coal seam interval eight indexes to built the evaluation model as the outburst main factor, the result of computation and actual verify, have indicated the reliability of method.
