| 摘 要： | 为了研究不同地貌条件对采场围岩的影响之间的差异,对两种不同类型的地貌进行模型简化,采用ANSYS软件进行数值模拟,把不同地貌影响下采场围岩的应力以及应变分布状况进行比较,分析后得到这两种地貌条件下应力、应变的差别,以及在开挖过程中对采场围岩稳定性的影响。结果表明:随着开挖的进行,在复杂的地貌条件下的采区应力应变的增加越来越快。该结果对今后在复杂地貌条件下矿的开发初期合理规划设计,选择安全合理的支护方案以及改善采场围岩应力分布状态,具有一定的指导意义。

| Abstract: | In order to study the difference of the impact of the distinct configuration of the physiognomy condition on stope wail rock,the paper simplifies the two kinds of physiognomy conditions and adopts the ANSYS software to carry out the numericai simulation.By comparing and analyzing the state of stress and strain of stope wail rock under the distinct configuration of the physiognomy condition,it gets the difference of stress and strain under the two kinds of configuration of the physiognomy condition,as well as the impact of stope surrounding rock stability. It turned out that with excavation going on the stress and strain of mining area under the complicated configuration of the physiognomy condition increase more and more quickly.The result may be significative to design the rational programming of the initial stage in the complicated physiognomy condition and choose safe and rational scheme of supporting and improve the state of stress of stope wall rock. |
