【摘要】：選取巖石密度、抗拉強(qiáng)度、巖體完整系數(shù)、波阻抗、抗壓強(qiáng)度、普氏堅(jiān)固性系數(shù)等6個(gè)因素作為巖體可爆性分級(jí)綜合評(píng)價(jià)模型的評(píng)判指標(biāo)�；谖创_知測(cè)度理論,建立未確知測(cè)度評(píng)價(jià)模型,結(jié)合熵權(quán)法和置信度評(píng)判準(zhǔn)則確定了6個(gè)評(píng)判指標(biāo)的權(quán)重以及評(píng)價(jià)等級(jí)的判定標(biāo)準(zhǔn),得到巖體可爆性分級(jí)的最終評(píng)價(jià)結(jié)果。運(yùn)用該綜合評(píng)價(jià)模型對(duì)貴州省晴隆縣某露天礦3個(gè)采區(qū)巖體可爆性難易程度進(jìn)行綜合評(píng)價(jià),并對(duì)該標(biāo)段內(nèi)不同采區(qū)爆破進(jìn)行優(yōu)化指導(dǎo),取得了較好的預(yù)期效果。
[Abstract]:Six factors, such as rock density, tensile strength, integrity coefficient of rock mass, wave impedance, compressive strength and Prussian stiffness coefficient, are selected as the evaluation indexes of the comprehensive evaluation model of rock mass blastability, based on the theory of unascertained measure. The evaluation model of unascertained measure is established, and the weight of six evaluation indexes and the criterion of evaluation grade are determined by combining entropy weight method and confidence degree evaluation criterion. The final evaluation results of rock mass blastability classification are obtained. The comprehensive evaluation model is used to evaluate the difficulty and ease of rock mass explosion in three mining areas of Qinglong County, Guizhou Province, and to optimize the blasting of different mining areas in this section. Good expected results have been obtained.
