根据采动岩体结构特点 ,进一步讨论采动岩体中普遍存在的自然咬合拱、巷道咬合圈、采场咬合梁、采场三咬拱、采场底板突水反三咬拱以及边坡咬合岩块等多种自然结构模型。并通过结构分析 ,得出前述咬合岩块结构的自由度 W=0 ,亦即 ,这些结构均为稳定静定结构。同时 ,阐述了采动岩体结构模型特点及采动岩体力学研究方面的若干进展。
According to the characteristics of the structure of the mining rock mass, the natural occlusion arch, the road occlusion ring, the bite beam of the stope, the three biting arch of stope, the bursting water in the stope and the bite of the slope are further discussed. Rock and other natural structure model. Through the structural analysis, the degrees of freedom of the above-mentioned briquetting rock block structure are obtained as W = 0, that is, these structures are stable and statically determinate. At the same time, some characteristics of the structural model of the mining rock mass and the mechanics of the mining rock mass are expounded.
