The Coal Mining Methods Selection of Large Mine Based on Grey Relevance Analysis

Abstract:

In order to select the reasonable coal mining method of large mine, analysing the main factors of affecting the mining method and establishing the evaluation index system of coal mining methods selection to large mine, then using Analytic Hierarchy Process (AHP) to calculate the weight of each index. The grey correlation evaluation model of mining method was established for large mine by using grey relevance analysis of the grey theory, this model can calculate grey relevance coefficient and grey relevance degree between the evaluation system indexes by determining the reference sequence and comparative sequence of the evaluation object, and according to the size of the grey relevance degree to determine the reasonable coal mining methods. The evaluating case analysis shows this model is practical to select the reasonable coal mining method of large mine, and it is a scientific decision-making method.
