A Solution Method for Reliability Evaluation of Dust-proofing Water Supply Network in pit

In-1 order to improve work environment and protect workers' health, the task of the water supply network is to reducing dust in pit, so the stable operation of water supply network is very important. In order to enhance the reliability of water supply network in pit, the model for reliability evaluation of dustproofing water supply network is established. The length, diameter, failure rate, both of repair time of pipe and water volume of node are determined as evaluation indexes in the paper. The paper adopts sobol sequence as the core of Quasi Monte Carlo method to simulate and solve the reliability evaluation model at the first time. Lin-nan mine is used as application and do statistical analysis for the results at last. According to the research, the pipes that are important to the network can be determined, what is more, the reliabilities of node and the entire network can be obtained.
