Abstract: Assessment index system for safety capability of team leader in coal mine is established to assess their safety capability accurately after defining its concept. The system is comprised of two layers, with 5 indexes in the first-layer and 14 indexes in the second-layer. Furthermore, the relative weights of indexes are determined by analytic hierarchy process (AHP). The grey relational assessment model for safety capability of team leaders is constructed based on the indexes system. The safety capabilities of 5 team leaders are assessed by the model in a coal mine, according to the sequences in their safety capabilities. Assessment for safety capability based on AHP and GRA could be a tool for evaluation and decision-making in coal mine enterprises.
