1996年，进行了一项研究，以评估在分散采矿环境中不同阶段和不同情况下的地震反应。对一个地质复杂的采矿区块内的七个不同区域进行了分析，试图从以下方面评估地震反应：深度不同；接近地质构造；向固体采矿；向已采空区采矿。这项分析使用了各种统计和地震活动参数，以描述和比较不同的采矿情况和岩石对生产的响应。根据预期应力水平、变形和相对地震危险性，尝试对地震观测进行岩石工程解释。用实际和合理的岩石工程术语解释地震观测是可能的，并发现一些参数是局部岩体硬度的良好指标，并可能与预期高水平应力诱发破裂的地区有关。由此得出结论，地震观测可以帮助进行日常的岩石工程分析，并作为一种决策工具。分散采矿环境中的地震活动--岩石工程解释
In 1996, a study was conducted to assess seismic response for different stages and situations in a scattered mining environment. Seven different areas within a geologically complex mining block where analysed in an attempt to assess seismic response in terms of: differences in depth; proximity to geological structures; mining towards solid and mining towards an already mined out area. This analysis was conducted using various statistical and seismicity parameters to describe and compare different mining situations and the rockmass response to production. A rock engineering interpretation of the seismic observations was attempted in terms of anticipated stress levels, deformation and relative seismic hazard. It was possible to explain the seismic observations in practical and logical rock engineering terms and it was found that some parameters were good indicators of the local rockmass stiffness and could be related to areas where high levels of stress induced fracturing were expected. From this it was concluded that seismic observations could assist in day-to-day rock engineering analyses and assist as a decision making tool.
