【Abstract】 Based on the practice on loose explosion and studying on gas outburst prevention,the technical factors that suited to the local coal seam conditions are summed. The gas strike-preventing theorem of loose explosion are initially approached in theory, and several main coefficients related to gas pressure are practically demonstrated, which has a reference action to the regulation of strike-preventing and technical scheme to the same kind seam.更多还原
