摘 要: | 矿井巷道瓦斯积聚是瓦斯灾害事故发生的前提条件。作者定义了矿井瓦斯积聚信息熵的概念,并给出了其计算关系式。通过对煤矿采区瓦斯积聚的实例分析,表明该指标不仅能反映瓦斯积聚的危险程度,而且还能反映出导致瓦斯积聚危险的不确定性因素的影响情况,因而这种基于信息熵的瓦斯积聚危险性分析评价更具有理论探讨价值。

Discussion on Hazard Evaluation of Mine Gas Accumulation Based on Information Entropy |
| |
Abstract: | Gas accumulation in a mine roadway is a prerequisite condition for the occurrence of gas accidents. In this paper, the authors defined the conception of information entropy of mine gas accumulation and gave the calculation formula. The analysis on the actual cases of gas accumulation in the winning district shows that this index can reflect not only the hazard degree of gas accumulation, but also the influence of uncertain factors of gas accumulation hazard, so the analysis and evaluation of gas accumulation hazard based on information entropy have further value for theoretical exploration. |
