以岩石的岩爆倾向性出发,选取了脆性岩爆指标、Barton岩爆指标、改进后弹性变形能岩爆指标和冲击能岩爆指标作为评价岩石岩爆倾向性的判别法则。对某深部矿山的主要岩石进行岩爆倾向性评价,并进行了相应的力学试验和计算,各岩爆指标的判别结果之间存在差异,为了更加准确、合理的对4种岩石的岩爆倾向性等级做出评价,将脆性岩爆指标判别法、Barton岩爆指标判别法、弹性变形能岩爆指标判别法和冲击能岩爆指标判别法的判别结果进行综合分析,得出了更加准确的判别结果。
Based on the rock burst tendency, the brittle rock burst index, Barton rock burst index, improved elastic deformation rock burst index and impact energy rock burst index are selected as the judgment rules of rock burst propensity. Rockburst propensity evaluation of the main rocks of a deep mine, and the corresponding mechanical tests and calculations are made. The differences between the results of the rockburst indexes are different. In order to more accurately and rationally predict the rockburst of the four types of rocks, The evaluation of brittle rock burst index, Barton rock burst index discrimination method, elastic deformation energy rock burst index discrimination method and the impact energy rock burst index discrimination method were used to make a comprehensive analysis and the results were more accurate Discriminant result.
