针对矿井通风系统安全综合评价中各指标的模糊性和随机性,从人-机-环境3个角度出发,建立二级安全模糊综合评价模型,采用改进的层次分析法(AHP)确定评价体系的指标权重,避免了一致性检验,提高了收敛速度、计算精度和多目标决策的可靠性,增强了矿井通风系统安全性评价的客观性和科学性。利用该模型对某金矿矿井通风系统安全性进行了评价,在MATLAB7.1中编程计算,根据分析结果指出其需要整改的薄弱环节。
Aiming at the fuzziness and randomness of each index in mine ventilation system safety comprehensive evaluation, the second-level safety fuzzy comprehensive evaluation model is established from the perspective of human-machine-environment. The AHP is used to determine the evaluation system Index weight to avoid the consistency test, improve the convergence speed, accuracy and reliability of multi-objective decision making, and enhance the objectivity and scientific evaluation of mine ventilation system safety. This model is used to evaluate the safety of the ventilation system in a gold mine mine and programmed in MATLAB7.1. According to the analysis results, it points out the weaknesses that need to be rectified.
