Abstract
At present, the methods of coal mine safety pre-evaluation are Fuzzy comprehensive evaluation, gray cluster analysis, matter-element analysis, BP artificial neural network, and so on. Pre-evaluation of coal mine safety is an effective method to ensure the safe operation of the mine production. Evaluation factors’ weight of every object related to coal mine safety is calculated according to these genes’ safety contribution rates, which would be put forward as a new method in this paper. After evaluation factor’s grade standards of the coal mine are treated properly, the continental distance model with varying weight, which would be capable to make a pre-evaluation of the mine, is established. After the application of this model to Huangling No.2 coal mine, the results of this model and unascertained measure model are compared and analyzed, which are excellently consistent.
