基于ISM和AHP的硫化矿石自燃危险性分析

为系统了解硫化矿石自燃的影响因素,从人-物-环-管四个方面找出18个硫化矿石自燃的影响因子.运用系统工程理论,建立硫化矿石自燃影响因素的6级多层递阶解释结构模型(ISM),采用层次分析法(AHP)确定各指标权重.研究表明,多层递阶ISM能有效地表达硫化矿石自燃影响因素的结构,18个影响因子可以分为6个层级,直观地反映出各个影响因素之间的层级及相互关系;AHP法求解出影响硫化矿石自燃的各级指标权重,表明矿石自身特性是影响硫化矿石自燃的决定性要素,管理则是深层次要素.

Analysis of spontaneous combustion hazard of sulfide ores based on ISM and AHP

In order to fully understand the impact factors of spontaneous combustion of sulfide ores, Eighteen factors which affect the spontaneous combustion of sulfide ores were Identified from the aspects of human, machine, environment, and management. By the theory of system engineering, the six-layer multi-hierarchical interpretative structure model (ISM) was established for spontaneous combustion of sulfide ores. The Analytic Hierarchy Process (AHP) was used to determine the weight of each index. The research results show that the affecting factors of spontaneous combustion of sulfide ores can be established effectively by multi-echelon ISM, eighteen factor can be divided into six levels , meanwhile the hierarchical and interrelation relationships among various factors can be reflected directly. Also, weight each index can be determined by AHP method; the physical and chemical properties of sulfide ores are key factors that affect the spontaneous combustion of sulfide ores, and management is a deep-seated factor. These provide reference for the prevention and control of spontaneous combustion hazard of sulfide ores.
