普遍认为 ,恰当地评价矿山硐室 (例如 :采场、巷道、通道 )的稳定性 ,对优化矿山设计和维持生产水平在某一运行成本之下非常关键。本文提出了一种在地下矿硐室设计中 ,用于检验硐室的形状、大小、方位效应以及支护要求的方法。在地下矿山巷道、采场的工程力学设计中 ,传统上采用经验的、数值的以及解析的岩石工程方法已经集成在一个综合软件包中 ,可用于矿山计划与设计。在给定的时间内 ,通过敏感性分析 ,工作人员就可以得到矿山设计训练的一部分的比较方案 ,侧重点放在比较方案的检验上。当实施部分矿山长期规划和可行性研究以及可以获得矿山设计方面的大多数可选方案时 ,敏感性分析就显示出特殊的意义。它们也能用作战术性工具改进生产矿山计划 ,或在地下矿山生产年限内反分析与地压有关的问题。给出了地下硬岩矿山设计的实例 ,从而展示敏感性分析的应用 It is generally accepted that a proper assessment of the stability of mine chambers (eg stopes, tunnels, tunnels) is critical to optimize mine design and maintain production levels at a certain operating cost. This paper presents a method for testing the shape, size, bearing effect and supporting requirements of chambers in underground mine chamber design. In underground mine tunnels and stope mechanics, the traditionally accepted numerical, analytical rock engineering methods have been integrated into a comprehensive package for mine planning and design. At a given time, through sensitivity analysis, staff members receive a comparative program that is part of mine design training, focusing on the testing of comparative programs. Sensitivity analysis is of particular significance when implementing some long-term mine planning and feasibility studies, as well as having access to most of the alternatives in mine design. They can also be used as tactical tools to improve mine production planning or to back-analyze problems with ground pressure during the life of underground mines. An example of the design of underground hard rock mines is given, demonstrating the application of sensitivity analysis
