发布时间:2018-11-22 16:04
【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。
[Abstract]:In order to objectively judge the danger of coal spontaneous combustion in goaf, the weight of evaluation index can be analyzed by entropy weight theory, which can effectively avoid the influence of subjective factors in the process of analysis and thus obtain a more objective weight coefficient. A comprehensive evaluation model of entropy weight extension is established. The prediction accuracy of this method is verified by an example of coal spontaneous combustion in goaf of a coal mine, and the conclusion is in accordance with the actual situation. The study shows that the entropy weight extension comprehensive evaluation method can better predict the spontaneous combustion of coal left in goaf, which provides a certain basis for the division of the "three zones" of spontaneous combustion in coal mines, and is easy to calculate and has guiding significance for practical production.
