In order to avoid the blindness of coal and gas outburst prevention, the Dashe mine of Fengfeng group combine with practical design and application of the KJ972-type coal and gas outburst prediction parameters monitoring system, collect gas, wind speed, temperature, carbon monoxide and other environmental parameters, to early warn and alarm the coal's and gas' outburst and fire of underground area. Each predictor that beyond the threshold is value of 1, otherwise 0 be assigned, and whether this Face outburst danger can be calculated using Boolean algebra. The results show that data parameters of the system and the status, the 3 d scene simulation figure can recognize the coal and gas outburst and the accident of time, place, and alarm automatically and timely, can automatically predict the gas emission and extent, effectively improve the mine safety coefficient.
