In order to accurately evaluate the reliability of the operation of mining belt transportation device and ensure mine safety production,an evaluation index system was established by referring to the relevant literature,which took the four factors of hu-man,machine,environment and management as the first index,and 18 factors such as the three failure rate of personnel and the ten thousand accident rate as the second index.The Best Worst Method(BWM)is used to determine the weight of each index,and the evaluation model is established according to cloud theory.Taking Donggucheng Coal Mine as an example,the reliability of the belt transportation device is evaluated by using the model.The reliability of belt transport equipment in Donggucheng Coal mine is good,and the evaluation results are consistent with the reality.The model can quickly and accurately evaluate the reliability of belt transpor-tation device in Donggucheng Coal mine,which provides a theoretical basis for the reliability evaluation of belt transportation device in Donggucheng Coal mine.
