“一矿二面”集中开采模式的综合效能度分析

Comprehensive Efficacy Analysis of Concentrative Mining Pattern of One Mine with Two Faces

将系统的时间利用率（有效度）和能力利用率（功效度）相结合，提出了综合效能度的概念和计算方法，以检测矿井运行的总体效果，并建立了功效度和有效度计算模型．通过对常村煤矿“一矿二面”开采模式的计算分析，选出了合理的集中开采模式并找出了矿井生产的薄弱环节．综合效能度的分析是有效、实用的，其结果对生产具有指导意义．

By combining availability with capacity efficiency, the concept of comprehensive efficacy is put forward to test the total effect of mine production. By calculating and analysing the comprehensive efficacy of concentrative mining pattern of one mine with two faces for Changchun Coal Mine, the reasonable concentrative mining pattern is selected and the weak links of mine production are also found. The analysis of comprehensive efficacy is effective and available.
