摘要
玲珑金矿是石英脉型金矿床 ,目前开采深度已超过 5 0 0 m ,未来开采深度将超过 10 0 0 m。对此类矿床赋存条件的地下矿山 ,深部开采时可能遇到的一个突出问题就是岩爆。根据系统的工程地质调查、地应力场现场实测、岩石力学试验、三维有限元数值模拟的结果 ,采用多种岩爆判断准则 ,分析了玲珑金矿深部开采时围岩中的能量分布规律和发生岩爆的可能性 ,提出了防治岩爆的建议措施。
The mining depth in Linglong gold mine is more than 500 m and will exceed 1 000 m in the future. Rock bursts will be a serious problem for the mine during deep mining excavation. Based on the results of systematical rock mechanics experiments and numerical modeling analysis, the distribution status of energy in surrounding rock mass and possibility of rock burst during deep mining excavation in Linglong gold mine are analyzed, using various prediction criteria of rock burst. The methods for protection of rock burst are also provided.
