| Abstract: | The prediction method of coal-gas outburst dangerous level was put forward based on outburst dangerous forecast and comprehensive prevention. The necessary to predicate coal-gas outburst dangerous level was discussed. In the coal and gas outburst dangerous level prediction method,the way to determine the sensitive index was proposed. The theoretic meaning of the various danger conditions in the outburst dangerous level prediction method was analyzed systematically. Fuzzy comprehensive prediction mathematical mode were established by using the pattern recognition technology and the critical value between two kinds of outburst dangerous states were determined. Outburst dangerous level prediction method was used in the mine to improve the coal roadway driving speed and the economic benefit of about 10 million yuan was obtained. |
