Coal Mine Safety, Factor Analysis, Index System, Evaluation Method.Abstract
The safe production of coal mine is an important part of national safety production, which is related to the healthy and stable development of coal industry. It is very important to find a comprehensive and reasonable coal mine safety evaluation method for coal mine safety production. In this paper, a comprehensive evaluation index system of coal mine safety is systematically established, and a comprehensive evaluation model of coal mine safety based on factor analysis principle is proposed. Then, with three Shanxi coal mine enterprises as examples for case study, we use principal component analysis and SPSS software to analyse the main factors influencing coal mine safety and their mutual relations on the basis of the details of each factor. By calculating the scores of principal components and the comprehensive safety score, we undertake a comprehensive analysis and evaluation on coal mine safety.
