【Abstract】 A coal and gas outburst pre-warning system was established in Yuyang Coal Mine in order to prevent and control the occurrence of coal and gas outburst and raise the safety guarantee ability of the mine. This paper made studies on the law of coal-bed gas geology, the influence of mining operation on outburst, the law of outburst prediction according to gas emission, the development law of routine prediction indicators, outburst-prevention measures and effective assessment methods as well as ventilation stability, determined a complete set of outburst pre-warning technologies suitable for this mine and set up a computer information platform for outburst prewaning and the pre-warning guarantee mechanism.更多还原
