In view of the problems such as high mining loss rate,poor stope production capacity and poor operation safety when short-hole room-and-pillar mining method and comprehensive mining method are adopted to mine the ore body thicker than 6 m in Jinshan Gold Mine,based on the technical conditions and present situation of the ore body mining in Wanjiawu mining area,four technically feasible and economically reasonable mining schemes are put forward,and the schemes are optimized by unascertained measure theory.The evaluation results of unascertained measure model show that 9 factors including operation difficulty,safety and applicability of each mining scheme are taken into full account before the sublevel open stope and footwall throw blasting filling mining method is determined to be the best mining scheme.
