摘要
为客观判定采空区煤炭自燃的危险性,采用熵权理论分析评价指标的权重,能有效避免分析过程中的主观因素影响,从而得出更客观的权重系数。建立了熵权可拓综合评价模型,利用某煤矿采空区遗煤自燃情况的实例,验证了此方法预测的准确性,得出了与实际情况相符的结论。研究表明,熵权可拓综合评价法能较好地预测采空区遗煤自燃,为煤矿自燃"三带"的划分提供了一定的依据,且计算简便,对实际生产具有指导意义。
In order to objectively determine the spontaneous combustion risk of coal in gob, using entropy weight theory for analyzing the weight of the evaluation indexes can effectively avoid the influence of subjective factors in the analysis process so as to obtain a more objective weight coefficient. An entropy weight extension comprehensive evaluation model was established, and by taking the spontaneous combustion situation of residual coal in the gob in a mine as examples, the prediction accuracy of this method was verified and it was consistent with the actual situation. The research showed that the entropy weight extension comprehensive evaluation method can be used to better predict the spontaneous combustion of residual coal in the gob, it provided a certain basis for the division of coal spontaneous combustion“three zone”, and its calculation is simple, so this research result has the instructive significance to the actual production.
