【摘要】：选取岩石密度、抗拉强度、岩体完整系数、波阻抗、抗压强度、普氏坚固性系数等6个因素作为岩体可爆性分级综合评价模型的评判指标。基于未确知测度理论,建立未确知测度评价模型,结合熵权法和置信度评判准则确定了6个评判指标的权重以及评价等级的判定标准,得到岩体可爆性分级的最终评价结果。运用该综合评价模型对贵州省晴隆县某露天矿3个采区岩体可爆性难易程度进行综合评价,并对该标段内不同采区爆破进行优化指导,取得了较好的预期效果。
[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.
