工作面煤与瓦斯突出危险程度预测技术研究

Prediction Method of Coal and Gas Outburst Dangerous Level in Coal Roadway Face

在工作面突出危险性预测及综合防治的基础上,给出了突出危险程度预测方法,阐述了进行突出危险程度预测的必要性;提出了突出危险程度预测方法中突出预测敏感指标的确定方法;系统地分析了在突出危险程度预测方法中各种危险状况的理论意义.采用模式识别技术,建立模糊综合预测数学模型,确定了2种突出危险状态之间的临界值;并将突出危险程度预测方法在煤矿进行具体应用,提高了煤巷掘进速度,并取得了上千万元的经济效益.

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.
