安太堡露天煤矿事故伤亡率影响因素的灰色关联分析研究

Study on the grey interaction analysis of effect factors of accident death rate in Antaibao open pit mine

利用线性变换及合理判定分辨系数的方法,确定了改进的关联系数,结合模糊系统中的贴近度原理,提出了一种改进的灰色关联度求法。通过实际分析,确定了影响安太堡露天煤矿事故伤亡率的因素,并对所有的因素模糊灰色化后进行了评定分析。

Linear transformation and reasonably judging resolution ratio are applied to determine the improved association coefficient and, combined with the principle of approach degree of fuzzy system and put forward a improved grey correlation method. Through analysis, the factors affecting death ratio of accident in Antaibao open pit mine are determined and the evaluation analysis is conducted after all the factors were fuzzy greyed.
