Extension Method of Safety Early Warning in Coal Mines

摘要

The safety early-warning indices system in coal mines was established in this article. The weights of indices in the safety early warning indices system were ascertained with the method of analytical hierarchy process. The synthetic safety early-warning model was put forward. The model is based on matter element model in extension theory. The comprehensive correlative degree was taken as the evaluation rule in the model. It can avoid the subjectivity in early warning. At the end, safety condition of Xinzhuang coal mine was analyzed by using the indices and the model of early warning established above.
