Comprehensive Evaluation of Bolt and Wire Mesh Support Scheme of Roadway Based on Set Pair Analysis

Set pair analysis is a combination of qualitative and quantitative methods used in decision-making. Aiming at the irrelevance of each indicator, an evaluation model of bolt and wire mesh support scheme of roadway based on set pair analysis is set up and a relativity to optimal scheme which combines multiple indicators as well as its set pair situation are applied to describe the comprehensive benefits of bolt and wire mesh support scheme. Evaluation results of three optional support schemes in a mine of Yaojie Coal and Electricity Co., Ltd are obtained using this method, and an optimal scheme with the best comprehensive benefits is determined.
