论文摘要
波兰铜的操作的最大风险是高能地震震颤，其中低层位于主屋顶层中。这些现象经常发生在几乎没有构造干扰的区域中。由于持续时间短和发生不可预测的时间，他们很难预测和分析。提出的分析的目的是在选定的档案地震事件之前确定所考虑的采矿面板内的整体应力/变形状态，然后判断采矿的进度如何影响屋顶岩石岩质量的不稳定性的发生。地质力学问题解决方案和结果可视化是基于在三个维度上使用FEM的Nei-Nastran计算机程序代码。
The biggest risk to operations in Polish copper is high-energy seismic tremors where hypocenters are located within the main roof strata. These phenomena occur often in the areas which are virtually free of tectonic disturbances. They are extremely difficult to both predict and analyze due to their short duration and unpredictable time of occurrence. The objective of the presented analysis was to determine the overall stress/deformation states within the considered mining panel prior to the selected archival seismic event and afterwards to judge how the progress of mining could affect the occurrence of instability in the roof strata rock mass. Geomechanical problem solution and results visualization were based on the NEi-NASTRAN computer program code utilizing FEM in three dimensions.
