Abstract The method of fuzzy theory is developed for optimization of six undermine patterns and relative parameters. The observation data are adopted for optimization，and the results show that the best undermine pattern is the wedge cut pattern. In the burn cuts，the better patterns are the compound cut and spiral cut. According to the actual result，the compound cut，spiral cut and diamond burn cut are recommended in the deep blasting.
