井下作业温度对事故影响关系的灰色关联分析

笔者基于灰色系统理论 ,结合煤矿井下运输生产实际 ,建立了以死亡人数为参考数列、以不同作业温度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 ,得到了不同作业温度对伤亡事故影响的灰色关联度 ,并据此分析结果而找出了井下作业温度对死亡事故的影响关系 ,为预防事故发生、减少伤亡损失及改善作业环境提供了有用的依据

Grey Correlation Analysis on the Impact of Temperature on Accident in Underground Pit Operation

On the basis of grey system theory, the grey correlation analysis system is set up, in which the number of death cases is referred as data array and different working temperatures are taken as comparison data array. Through non dimensional treatment of different data to give sequence in different form and grey correlation coefficient, the grey correlation of the impact of different working temperatures on fatality is obtained. The influence of the underground working temperature to the casualty in coal mine is determined. It also provides the criteria for preventing accident, decreasing the casualty and improving the working environment.
