Reliability Evaluation of Mine Water Supply Network Based on AHP-Fuzzy

The reliable operation of the mine water supply network is the guarantee of the effective implementation of mine dust prevention facilities. In this paper, a reliability evaluation indicator system was established by comprehensively analyzing the factors affecting the reliability of the mine water supply network in order to improve its operation reliability.The analytic hierarchy process (AHP) was applied for determining the weights of the evaluation indicators at all levels, and then the fuzzy comprehensive evaluation method was used to evaluate the reliability of the mine water supply network.The water supply network of Linnan Mine of Kailuan Group was taken as en engineering example for evaluation. The evaluation results showed the moderate hazard and conformed to the present situation of the mine water supply network.
