基于灰色关联的金属矿山通风与作业环境分析

基于灰色系统理论,结合金属矿山通风实际,建立了以合理通风为参考数列,以不同井下作业环境为比较数列的灰色关联分析体系.通过对构造的不同数据列的无量纲化处理、求取差序列、计算灰色关联系数等,得到了不同作业环境与通风影响的灰色关联度,并据此分析结果找出了井下作业环境与通风的影响关系,为进一步改善作业环境与量化通风效果提供了有用的依据.

Research on Ventilation and Work Environment in Underground Metal Mines Based on Grey Correlation Analysis

Based on the gray system theory and the ventilation reality of underground metal mines,the gray correlation analysis system is set up,with the reasonable ventilation data as the standard data array and those of different underground work environment states as the correlation data array.Through the dimensionless treatment of the different data arrays of the structure,searching for the difference sequence and calculating the gray correlation coefficient,the g degree of gray correlation of the various work environment states to the impact of ventilation is found.Based on the result,the relationship between the underground work environment and the ventilation effect is determined,thus providing a useful basis for the further improvement of work environment and the quantification of ventilation effect.
