摘要: 岩爆作为矿山深部开采中的典型动力学灾害,严重威胁着矿山的安全生产和工程进 度,因此,准确评估岩爆风险,特别是岩爆发生的特征,对于深部开采的安全性至关重要。以蚕庄 金矿上庄矿区为研究对象,系统分析了深部开采过程中可能面临的岩爆风险。研究采用岩石力学 试验、Hoek-Brown 强度准则折算、水压致裂法原位地应力测试及数值模拟等方法,为岩爆风险评估 提供了基础数据。结合历史数据,进行了地压分布规律的模拟,并进一步探讨了岩爆发生的倾向 性。研究结果表明,岩爆的发生与埋深和岩体的应力状态密切相关,上庄矿区的上下盘在埋深约 700 m 时可能出现轻微的块状岩石剥落岩爆,而点柱矿体在埋深约 500 m 时亦存在类似的岩爆风 险。模拟结果还表明,随着采矿深度的增加,岩爆发生的倾向性明显增强,特别是在应力集中的区 域,岩爆风险进一步加剧。通过深入分析岩爆发生的规律,提出了优化采矿设计和防控措施的建 议,为矿山安全生产和岩爆防治提供了有效的参考。

Abstract: As a typical dynamic disaster in deep mining,rockburst poses a serious threat to the safe‐ ty production and engineering progress of mines. Therefore,accurately assessing the rockburst risk,espe‐ cially the characteristics of rockburst occurrence,is crucial for the safety of deep mining operations. This study focuses on the Shangzhuang mining area,Canzhuang Gold Mine,and systematically analyzes the rockburst risk during deep mining. Various methods including rock mechanics tests,the Hoek-Brown strength criterion for parameter conversion,hydraulic fracturing for in-situ stress testing,and numerical simulation were employed to provide foundational data for rockburst risk assessment. Historical data were used to simulate the ground pressure distribution,and the tendency of rockburst occurrence was further ex‐ plored.The results indicate that rockburst occurrence is closely related to mining depth and the stress state of the rock mass. Slight block rockfalls are likely to occur at a depth of approximately 700 m in the hanging and footwalls of the Shangzhuang mining area,while a similar risk of rockbursts exists in the point pillars at a depth of around 500 m. Furthermore,the simulation results show that as mining depth increases,the tendency for rockbursts becomes significantly stronger,particularly in regions of stress concentration, where the rockburst risk further intensifies. By analyzing the occurrence patterns of rockbursts,recommen‐ dations for optimizing mining design and implementing preventive measures are proposed,offering valu‐ able references for mine safety production and rockburst prevention.
