【摘要】:基于未確知測(cè)度理論,建立了露天礦總承包安全評(píng)價(jià)指標(biāo)體系。采用專(zhuān)家打分法對(duì)所選取的25項(xiàng)綜合評(píng)價(jià)指標(biāo)進(jìn)行綜合打分,并做定量分析,確定了在不同評(píng)價(jià)等級(jí)下各指標(biāo)的未確知測(cè)度,并利用熵計(jì)算各指標(biāo)的權(quán)重,最后根據(jù)置信度識(shí)別準(zhǔn)則得出露天礦總承包安全評(píng)價(jià)結(jié)果。結(jié)合某露天礦實(shí)例分析表明,該方法計(jì)算合理,明確了總承包開(kāi)采下該露天礦的安全現(xiàn)狀,為露天礦總承包安全評(píng)價(jià)提供了一種新的思路,可在類(lèi)似工程環(huán)境中推廣應(yīng)用。
[Abstract]:Based on the theory of unascertained measure, the evaluation index system of general contract safety of open pit mine is established. The expert scoring method is used to synthetically score 25 comprehensive evaluation indexes selected, and quantitative analysis is made to determine the unascertained measure of each index under different evaluation levels, and to calculate the weight of each index by using entropy. Finally, according to the confidence recognition criterion, the result of general contract safety evaluation of open pit mine is obtained. The analysis of an open pit mine example shows that the method is reasonable, and the present safety situation of the open pit under general contract mining is clear, which provides a new idea for the general contract safety evaluation of open pit mine, and can be popularized and applied in similar engineering environment.
