| 中文摘要:为了准确预测花脑特矿区深部中段岩爆倾向性，选取岩石单轴抗压强度、冲击能量指数、弹性应变能指数、地应力指数和RQD值5个指标，通过地应力测量、室内岩石力学试验、Sirovision岩体节理裂隙调查，获得岩爆倾向性单指标评价结果，同时引入变异系数-突变级数法建立岩爆多指标评价体系，利用岩爆倾向性单指标评价结果计算突变级数值，并与岩石实际岩爆等级进行比较分析。结果认为样本突变级数值与实际岩爆等级存在正相关关系。研究表明：变异系数-突变级数值法在白音呼布花脑特矿区具有较好的适用性，可作为矿山后续工程中岩爆倾向性预测依据。 |

| Abstract:In order to predict the rockburst tendency of the mining area accurately, five indexes of rock uniaxial compressive strength, impact energy index,elastic strain energy index, ground stress index and RQD value are selected to obtaine the single index evaluation results of rockburst tendency through the ground stress measurement, indoor rock mechanics test, and rock joint and fissure investigation with Sirovision. At the same time, the method of variation coefficient-mutation series was introduced to establish a rockburst multi-index evaluation system, and the mutation series value was compared and analyzed with the actual rockburst level. The results shows that the mutation series value is positively correlated with the actual rockburst leval, the research results show that the method of variation confficient-mutation series has good practicability in the Huanaote mining area of Baiyinhubu Gold Mine and can be used as a follow-up rockburst prediction basis in the mine. |
