Abstract: Aiming at the characteristics of high gas, low permeability and close distance outburst coal seam group mining in western guizhou complex geological conditions, the application of coal and gas simultaneous extraction concept, this paper puts forward protective seam mining combined with high pumping lane and cross hole drilling extraction pressure relief gas plan,constructs the coal and gas simultaneous extraction technology system of coal seam group, and effectively solves coal and gas outburst and gas overrun problems of outburst coal seam group mining, creates the conditions for safety and efficient production, realizes coal and gas safety and efficiency simultaneous extraction.
