| 摘 要： | 通过对冬瓜山矿体岩石力学特性的分析,探讨了矿体特征及围岩性质、原岩应力、岩石物理力学性质、岩体的整体稳定性,以及矿岩构造条件、采场结构参数和采场回采顺序对巷道稳定性的影响.结果表明:冬瓜山矿体表现出软岩的性质,属于高应力软岩;冬瓜山矿体地应力场的分布规律可以作为矿山设计及岩体稳定性评价的依据;矿岩构造条件对矿床开采过程巷道的稳定性不会造成较大的影响;选择合适的采场结构参数和采场回采顺序,可减小对巷道稳定性的影响. |

| Abstract: | The rock mechanics behavior of the Dong Gua Shan's orebody is analysed,including orebody characteristics and the nature,stress,physical and mechanical properties,and overall stability of the rock.The effect of rock structure conditions,stope structure parameters and stope mining order on laneway stability are also analysed.The results show that: Dongguashan orebodies are high stress soft rock;the distribution of stress field can be used for design and stability evaluation;ore deposits tectonic conditions wi... |
