| 摘 要： | 为了研究渣滓溪锑矿井下主要岩石的岩爆倾向性, 以便有针对性地采取防治措施, 采用岩体脆性指数、弹性变形能指数、冲击能指数和剩余能量指数4种岩爆倾向性判别指标, 分别研究了井下凝灰质板岩、凝灰质砂岩、石英砂岩和锑块矿4种岩石的岩爆倾向性, 结果表明, 在具备一定外力的条件下, 凝灰质砂岩无岩爆可能性, 凝灰质板岩可能发生中等岩爆, 石英砂岩肯定发生中等及以上岩爆, 锑块矿肯定发生强烈岩爆。同时结合调查区域井下岩爆的实际发生情况, 进一步论证了该结论的科学性。

| Abstract: | In order to study rock burst proneness of main rocks underground in Zhazixi Antimony Mine for finding some preventive measures, four discriminant indices, including rock brittleness, elastic energy, impact energy, and residual energy, were adopted for 4 kinds of rock, such as tuffaceous slate, tuffaceous sandstone, quartz sandstone, and antimony ore. Results showed that under some external force, a violent rockburst will definitely occur in antimony ore and a moderate or stronger rockburst will certainly occur in quartz sandstone, while tuffaceous slate probably has a moderate rockburst and tuffaceous sandstone won't have any rockburst. This conclusion was verified by a further investigation of practical rockburst underground. |
