Abstract: In light of the difficulties in evaluating the quality of conventional stope mining such as acquiring accurate technical and economic indicators and establishing a suitable mathematical model, a comprehensive fuzzy math evaluation method based on site survey is proposed. An evaluation index system is built based on the technical parameters such as dilution and loss of the mining obtained by CMS system and the mining economic indexes provided by the mine information system. Normalization and weight value for each index are made and a quality evaluation model for stope mining is constructed based on the developing criteria for optimal least-squares and fuzzy math theory. Its practical application shows that the evaluation index parameters obtained can accurately reflect the real conditions of stope mining and the model can be used to effectively realize a quantitative evaluation of the quality of stope mining, providing a new method for managing the mining quality.
