中文摘要: 本文在地应力测试和岩石力学参数试验的基础上,首先采用单指标评价法,如:岩石脆性系数法、能量冲击性指数法、岩石弹性能量指数法等, 对阿舍勒铜矿部岩体的岩爆倾向性和烈度大小进行了预测,发现采用不同的岩爆倾向评价方法,其结果会存在一定的离散性。基于单指标评价结果,采用模糊数学评判法,建立数学模型,对阿舍勒铜矿深部围岩体岩爆倾向性进行了综合分析计算,评判结果表明:凝灰岩、铜硫矿、黄铁矿三种岩性岩爆倾向性分别为弱岩爆倾向、中等岩爆倾向、中等岩爆倾向,评判结论与现场实际情况吻合, 表明使用模糊数学综合评判法预测岩爆倾向性可靠有效。

Abstract:Based on the ground stress test and rock mechanics parameter test, this paper firstly used single index evaluation method, such as rock brittleness coefficient method, energy impact index method and rock elasticity energy index method, to predict the rockburst propensity and intensity of the rock body in the Ashele copper mine, and found that the results of different rockburst propensity evaluation methods will have certain dispersion. Based on the results of the single-indicator evaluation, a fuzzy mathematical evaluation method was used to establish a mathematical model and carry out a comprehensive analysis of the rockburst propensity of the deep surrounding rocks of the Ashele copper mine body, the evaluation results show that: tuff, copper-sulphide ore, pyrite of the three lithologies rockburst propensity are weak rockburst propensity, medium rockburst propensity, medium rockburst propensity. The results are consistent with the actual field conditions, indicating that the use of fuzzy mathematics to predict the rockburst propensity is reliable and effective.
