摘要： 在应用三维岩体不接触测量系统对采场顶板岩体结构面的几何特征参数进行识别基础上,自行研发三维岩体节理建模与分析系统,构建采场顶板三维岩体结构面空间分布模型.依据采场顶板岩体结构面的几何特征参数和延伸节理等结构面的空间特征,通过延伸节理等结构面的空间交汇,识别采场危岩体赋存的空间位置、形态、体积等,并对采场顶板危岩体稳定性进行判断.应用上述研究成果,对三山岛金矿新立矿区40055#采场顶板结构面进行现场测量,确定采场顶板危岩体空间赋存位置,为采场顶板稳定性分析和危险性评价提供更加真实、可靠的数据支持.

Abstract: A 3D rockmass non-contact surveying system was employed to identify the space geometry parameters of stope roof. Based on this, a new 3D joint modeling and analyzing system was developed, and applied to set up 3D spacing model of stope roof, including the joint structure. According to space geometry parameters of structural plane of stope roof, structural plane, such as joint, fault and constitution, were stretched, which will intersect in spacing position and form the wedge structure. The spacing position, shape, and capacity of the wedge structure can be recognized, and its stability of the wedge structure can be analyzed. By applying these studying results, the spacing structure of stope roof has been surveyed and established the 3D modeling in 40055# stope of Sanshandao Golden Mine. The spacing position of unstable rockmass has been determined on site, which can provide the real and reliable data helpful to the analysis of the stope stability and evaluation of risk.
