【摘要】:為客觀判定采空區(qū)煤炭自燃的危險(xiǎn)性,采用熵權(quán)理論分析評(píng)價(jià)指標(biāo)的權(quán)重,能有效避免分析過程中的主觀因素影響,從而得出更客觀的權(quán)重系數(shù)。建立了熵權(quán)可拓綜合評(píng)價(jià)模型,利用某煤礦采空區(qū)遺煤自燃情況的實(shí)例,驗(yàn)證了此方法預(yù)測(cè)的準(zhǔn)確性,得出了與實(shí)際情況相符的結(jié)論。研究表明,熵權(quán)可拓綜合評(píng)價(jià)法能較好地預(yù)測(cè)采空區(qū)遺煤自燃,為煤礦自燃"三帶"的劃分提供了一定的依據(jù),且計(jì)算簡(jiǎn)便,對(duì)實(shí)際生產(chǎn)具有指導(dǎo)意義。
[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.
