【摘要】：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。
[Abstract]:Based on the tendency of rock burst, brittle rock burst index, Barton rock burst index, improved elastic deformation energy rock burst index and impact energy rock burst index are selected as the criteria for evaluating rock burst tendency. In order to be more accurate, the rockburst tendency of the main rock in a deep mine is evaluated, and the corresponding mechanical tests and calculations are carried out. There are differences between the discriminant results of each rock burst index. The classification of rock burst tendency of four kinds of rocks is evaluated reasonably. The discriminant results of brittle rock burst index, Barton rock burst index, elastic deformation energy rock burst index and impact energy rock burst index are analyzed synthetically. A more accurate result is obtained.
