回采工作面安全性灰色评价模型分辨系数p对评价结果的影响分析

Effect Analysis of Resolution Coefficient p on Safety Grey Evaluation of Operating Environment in Working Faces

阐述了对回采工作面安全性进行客观而准确评价的重要性。灰色关联理论应用于安全评价过程中 ,就其分辨系数 p选择所存在的问题进行了理论分析 ,并用实例验证了分辨系数对评价结果的影响 ,得出了分辨系数 p必须大于 0 .4的结论。这对灰色关联理论在安全评价中的应用研究 ,具有一定的参考价值。

The importance of objective and correct evaluation on the working environment in working faces was described. Some problems about the selection of the resolution coefficient p in the application of the grey interrelated theory were analyzed. The effect of this coefficient on the evaluation result was exemplified. It could be concluded that the resolution coefficient p should be greater than 0.4.
