定义了矿柱模型和矿柱结构体模型基本概念。以选定矿柱模型区域相关巷道结构面调查数据为基础,利用General Block程序的块体计算功能初步解构出矿柱结构体。根据矿柱结构体真实性分析结果,结合几何方法,精确解构出矿柱结构体空间禀赋形态。基于结构体破坏形式建立力学模型,计算出固定结构体的最小固定面面积。运用力学与集合方法分析矿柱真实结构体的移动机制,推导出结构体稳定性系数计算公式。
The basic concepts of pillar model and pillar structure model are defined. Based on the survey data of structural planes of the relevant tunnels in the selected pillar model area, the pillar structure was preliminarily deconstructed by using the block calculation function of General Block program. According to the result of authenticity analysis of pillared structure and geometric method, the spatial endowment of pillared structure is precisely deconstructed. The mechanical model was established based on the structural damage, and the minimum fixed surface area of the fixed structure was calculated. The mechanics and collection method are used to analyze the movement mechanism of the real structure of mine pillar, and the calculation formula of the stability coefficient of the structure is deduced.
