The safety evaluation Assessment is an important content in coal mine safety Management. An- other evaluation models on coal mine safety for China have been proposed in this article, which based on the basic theories of principal component analysis and factor analysis. First, the evaluation index system on coal mine safety was established which overcame the lacks on the indicators system established by our pre- decessors，and then, factor analysis was used to evaluate the safety of a coal mine. From another point of view on the evaluation of coal mine safety, this paper has a certain amount of theoretical and practical sig- nificance in our community.
