There were so many upward mining examples in chinese coal mine production and its safety was a priority subject concerning safety production and sustainable development. In order to research feasibility of upward mining in XV1201 working face, four methods were analyzed in this paper. The result including: ① 12 coal upward mining was viable without being affected by 10 coal seam through ratio method. ② 12 coal upward mining was viable on the basis of 12 coal seam overall movement without destorying its integrity after mining of 10 coal seam through “three band” discriminance. ③ through discriminance of wall rocks balance, overlying strata coal seam of equilibrium surrounding rock would not have step dislocation because actual mining distance of coal seam was greater than necessary layer distance, so upwarding mining of 10 coal seam was viable. ④ according to time interval discrimination, 12 coal seam mining laggged 10 coal seam mining time to meet conditions which showed that upwarding mining of 12 coal seam mining was viable. All above upwarding mining were viable based on comprehensive comparison.
