【Abstract】 According to the three mechanical conditions advanced in the hypothesis of “spherical shell losing stability” about outburst mechanism, a new method which restrains coal and gas outburst by increasing atmospheric pressure in tunnels was put forward. Through 10 restraining outburst and relevant contrast experiments, it is verified that the danger of coal and gas outburst can be reduced notably by increasing the atmospheric pressure in tunnels, and that this method is a safe and rapid one to prevent and control coal and gas outburst.更多还原
