摘要
针对煤与瓦斯突出存在诸多不确定影响因素的特点,在研究煤与瓦斯突出机理和集对分析理论的基础上,确定了突出区域预测指标,划分了突出危险等级和指标临界值,计算各突出危险等级的联系熵范围,从而构建了煤与瓦斯突出区域的联系熵预测方法.通过应用实例预测,计算结果与实际情况相吻合,证明了该预测方法的合理性和可行性,对煤矿实现煤与瓦斯突出区域预测具有一定的指导意义.
According to the characteristics of existing many uncertain influencing factors in coal and gas outburst, on the basis of studying the theory of the coal and gas outburst and set pair analysis, this paper gave the forecasting indexes of outburst, divided the risk degrees and the critical value of their index, ensured the scope of connection entropy, and then built regional forecast method of coal and gas outburst based on connection entropy. After forecasting on instances and analyzing their results, it showed that this method＇ s calculation is simple and the results were fit to actual situation. The study results proved rationality and feasibility of this method, and it would be more guiding significance to regional forecasting of coal and gas outburst.
