摘要: 为研究硫化矿尘氧化自热的影响因素,以硫化矿尘层氧化自热温度和产生二氧化硫时的内部温度为指标,以硫化矿尘的含硫量、矿尘层厚度和矿尘粒径为自变量,进行3因素3水平正交试验获得硫化矿尘层开始氧化自热时的初始温度和产生二氧化硫时的内部温度,利用灰色系统理论分别计算影响因素对单目标函数的关联系数和多目标函数的关联度,将多目标转换为以关联度为目标的单目标进一步计算各影响因素的平均关联度,从而得出硫化矿尘最易发生氧化自热的条件,为高硫矿山安全生产提供依据。

Abstract: In order to investigate factors of the oxidation and self-heating of sulfide dust,and using the oxidation and self-heating temperature of sulfide dust and inner temperature when sulfur dioxide was produced as an indicator,and sulfur content,mine dust layer thickness and dust particle size of the sulfide dust as independent variables,the oxidation and self-heating initial temperature of sulfide dust and inner temperature when sulfur dioxide produced were gained by three factor and three level orthogonal tests.Gray system theory is used to calculate correlation coefficient of influencing factor to correlation degree of single objective function and multiple objective functions.And the average correlation degree of every influencing factor is calculated during transition from multiple targets into single target at correlation degree.Then,the condition for most easily occurring oxidation and self-heating of sulfide dust is obtained,which provides the basis for safe production of sulfur mine.
