摘　　要：基于岩石抗压强度、抗拉强度、黏聚力、弹性模量、岩石密度、岩体地质力学分类等技术指标，建立了岩体可爆性分级准则，通过未确知测度熵权模型对某磷矿矿岩可爆性分级进行评价，解决了岩体可爆性分级中不确定信息的综合、定量评价问题，确保了评价指标信息的完整性和评价结果的客观性。Based on the uniaxial compressive strength, extension strength, cohesive force, elasticity modulus, rock density, rock mass rating （RMR）, the criterion of rock-mass blastability classification is established. By the means of unascertained measure and entropy weight model, the rock-mass blastability classification of a phosphorite mine is evaluated, which resolve the problems of comprehensive quantitative assessment of uncertainty information in rock-mass blastability classification. This method ensured the integrity of the assessing information and the objectivity of the evaluation results.
