岩体中广泛存在规模不等、性质各异的结构面,是控制岩体稳定性的重要因素。深入了解工程岩体的构造特征,也是组织矿山设计和施工的前提。本文以影响岩体工程稳定性的岩体结构面为主要研究对象,以实际矿山为例,在大量钻孔资料的基础上,通过分析岩体的工程地质条件及各种力学特性,得出岩体构造特征指标的统计分布规律,然后结合岩体质量分类方法,对矿岩体进行质量评价分级。研究结果很好的揭示了工程岩体的整体性质,对矿山的后续工作具有重要的指导意义。
There are a large number of structural planes with different sizes and different properties in rock mass, which are important factors to control the stability of rock mass. A thorough understanding of the structural features of engineering rock mass is also a prerequisite for organizing mine design and construction. In this paper, the rock mass structural plane that affects the stability of rock mass engineering is the main research object. Taking the actual mine as an example, based on a large amount of drilling data, the rock mass engineering geological conditions and various mechanical characteristics are analyzed, Body structure characteristics of the statistical distribution of indicators, and then combined with rock mass classification method, the quality of ore rock mass grading. The research results reveal the overall quality of engineering rock mass and have important guiding significance for the follow-up work of the mine.
