矿井降温系统方案决策指标及权值确定

While there is serious heat harm in the mines which are under construction and in production, and it’s necessary to design mine refrigeration cooling system. In order to determine the optimal mine refrigeration cooling system, we should compare the various schemes in economy and technology. In this paper, 10 evaluation indicators which could be used in mine cooling system optimization and decision-making have been established with \"Delphi method\"; the weights of each index have been derived with the method of the relative importance of the sequence of matrix; the degree having carried out significance on every index is ordered. All of this laid the foundation for mine cooling system optimization and decision-making.
