摘要: 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 GeneralBlock 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。

Abstract: The fundamental concepts of pillar model and pillar structure body were defined in this paper. Based on the survey data of structural planes of the roadways related to the selected area of pillar model, the block calculation function of GeneralBlock was used to preliminarily deconstruct the pillar structure bodies. According to the authenticity analysis results of pillar structure bodies, the spatial endowment situation of pillar structure bodies was accurately deconstructed by using geometric method. Based on the failure modes of structural body, the mechanical model was built and the area of the minimum fixed surface of the fixed structural body was calculated. The mobility mechanisms of the real pillar structure bodies were analyzed by using mechanics and collection methods, and the calculation formula of stability coefficient of the structure body was derived.

Key words: pillar, structural body, deconstruction, block theory, stability
