Abstract

Ground-related problems represent a significant source of operating risk and justify particular attention in proactive mine planning and design. This paper presents a new approach to quantify the impact of such problems in underground hardrock mining and considers the links between mine planning and ground-related problems. A classification of the various types of potential problems is presented, based on a review of case studies and the surveillance of ground failures in several mines in Ontario, Canada. Despite serious efforts to advance the effectiveness of design in such underground mines, ground-related problems still cannot be totally avoided. A time-dependent internal risk model was established to quantify the impact of ground-related problems in mine production systems. Subjective probabilities provide the input for a reliability analysis, which derives the required input parameters for production simulation. Reliability analyses that are currently used to calculate the reliability of mine equipment were applied for the case of mine subsystems with ground-related problems. A cost impact model is presented that is dependent on the parameters determined in a reliability analysis.

矿山生产系统规划中与地面有关问题的核算

与地面有关的问题是作业风险的一个重要来源，因此需要特别注意主动的矿山规划和设计。本文提出了一种量化地下硬岩开采中此类问题影响的新方法，并考虑了矿山规划与地面相关问题之间的联系。根据对加拿大安大略省几个矿山的案例研究和地面故障监测的审查，提出了各种类型潜在问题的分类。尽管在这类地下矿山中努力提高设计的有效性，但与地面有关的问题仍然不能完全避免。建立了一个随时间变化的内部风险模型，以量化与地面有关的问题对矿山生产系统的影响。主观概率为可靠性分析提供输入，从而导出生产模拟所需的输入参数。将目前用于矿山设备可靠性计算的可靠性分析方法应用于具有接地问题的矿山子系统。提出了一个依赖于可靠性分析中确定的参数的成本影响模型。
