摘　　要：为推进岩体可爆性分级后的进一步工程实际应用,利用回归分析方法分析可爆性指标的相关性,最终确定以岩体的抗拉强度、密度、脆性指数、完整性系数4个基本不相关的参数作为评级指标;通过正交试验设计确定各评级指标的敏感性,并确定其权重;运用模糊决策理论对岩体进行可爆性评级,采用评级指标结合岩体基本质量指数,推出地下采矿浅孔爆破的炸药单耗预测公式,进一步推导出可爆性等级对应的炸药单耗预测区间。结果表明:模糊决策方法为岩体可爆性评级提供了一种新思路,同时也证明了权重分配与评级指标选取的正确性。现场爆破试验证明了炸药单耗预测区间的合理性,研究结果可为生产爆破和类似工程实践提供一定的指导。In order to promote the further practical application of rock mass explosivity classification in engineering,regression analysis method was used to analyze the correlation of explosivity indicators,and finally determine the four basically unrelated parameters of rock mass tensile strength,density,brittleness index,and integrity coefficient as rating indicators.The sensitivity of each rating index and its weight were determined using orthogonal design experiments.By using the method of fuzzy decision-making,the explosivity of rock mass was rated,and based on the rating index and the basic quality index of rock mass,a formula for predicting the explosive unit consumption of shallow hole blasting in underground mining was derived.The corresponding explosive unit consumption prediction interval for the explosivity level was further derived.This research shows that the fuzzy decision-making method provides a new approach for rock mass explosivity rating,and also proves the correctness of weight allocation and rating index selection.The on-site blasting test has proven the rationality of the predicted range of explosive unit consumption,which can provide certain guiding significance for production blasting and similar engineering practices.
