基于AHP的金属非金属矿山通风系统综合评价模型研究

Study on Comprehensive Evaluation Model for Metal and Non-metal Mine based on AHP

金属非金属地下矿山通风系统是由相互制约、相互关联的多因素构成的复杂的、动态的系统,而各因素之间又存在矛盾性和不可公度性,决策过程中不能简单的把多个指标归并为单个指标求解,应选用多指标进行科学决策。工作面是通风系统的服务核心,本文围绕“人-机-环”科学理念,建立技术、经济的通风系统管理评价指标体系,并应用层次分析法对其评价指标权重因数进行计算。结果表明风速(风量)合格率和风质合格率应放在矿井通风系统管理首要位置,对于通风研究及管理具有实用参考价值。

The ventilation system of underground metal or non-metal mine is a complicated,the dynamic system which is composed of mutually restricted,correlative multi-factors,and in the multi-factors,the contradictoriness and the non-commensurabilities are existed in,therefore in the decision-making process,rather than taking the multiple indicators into the individual indicators to solve,and the multi-indicators shall be selected for scientific decision-making.Working face is the service core of ventilation system,the technical,economic management evaluation indicators system of ventilation system is established based on the scientific concept“human-machine-environment”,and the analytic hierarchy process shall be applied for calculation of the weighting factors of the evaluation indicators.The results show the qualified rate of wind speed(blast volume)and the qualified rate of wind quality shall be the primary position of the mine shaft ventilation system,which has the practical reference value for study and management of ventilation.
