Application of the Entropy Weight and TOPSIS Method in Safety Evaluation of Coal Mines

In this paper, evaluation index system of coal mine safety is established on the basis of the SMART principles. Weights of indexes are determined by means of entropy weight method. Safety conditions in four coal mines are applied by used of TOPSIS and the method is compared with other evaluation methods. The case study shows that the method is simple and clear, the evaluation results are reliable which are more coincident with the reality. So the method should be promoted widely in safety evaluation of coal mines.
