| 摘 要： | 采用合理的矿床开采顺序可以改善岩体应力分布及其变形破坏程度，对于深部矿床二步骤安全回收矿性及预防岩爆意义重大。作者根据冬瓜山矿床岩体物理力学性质及地应力场特点，构造了弹塑性理论计算模型，并采用屈服函数作为复杂应力条件下的岩体破坏判据，对矿床的不同开采顺序进行了有限元数值模拟分析，从战略上为冬瓜山深井开采地压控制提供了决策依据。 |

| Abstract: | Adopting reasonable order in ore deposit exploiting can ameliorate rock body's stress distributing and its distortion and destructive extent,which has important sense to safely reclaim pillar and guard against rock blasing in deep well ore deposit.According to the characteristics of rock mechanics and crust stress appearing in Dongguashan deep well ore deposit,a computational model based on elastic plastic theory has been constructed,and regarded the yield function as judgement to rock damage under complicated stress.Then author analyzed the rock stability of defferent ore deposit exploiting order by numerical simulation based on finite element software.The results of numerical simulation can be taken as decision making reference to geopressure control in Dongguashan deep well exploitation. |
| Keywords: | deep ore deposit mining earth stress finite element numerical simulation |
