摘要
研究岩爆倾向性对深井矿山的安全开采具有十分重要的意义。以某矿山为研究对象,采用一维云模型与多维云模型结合的手段,选取岩石应力系数、岩石脆性系数及岩石弹性应变能指数构建指标体系,对不同开采中段的3种矿岩进行岩爆倾向性评价。结果表明:该矿山设计开采范围(50 m~-450 m中段)内,顶板围岩整体为弱岩爆倾向,矿体整体为中岩爆倾向,底板围岩整体为弱岩爆倾向。
The rockburst proneness study is of great significance for safe operation in deep mines.Taking a mine as the research subject,a combination of one-dimensional and multi-dimensional cloud models was used to construct an index system using the rock stress coefficient,rock brittleness coefficient,and rock elastic strain energy index,for evaluating the rock burst proneness of ore rocks with 3 types of lithology in different mining levels.The results showed that within the designed mining range of the mine(levels from 50 m to-450 m),the roof dolomite exhibited an overall lesser rockburst proneness,the ore body showed a moderate rockburst proneness,and the surrounding rock of the floor exhibited an overall lesser rockburst proneness.
