Abstract
According to the selected backfill mining of Luohe iron mine, the engineering geological conditions, Bieniawski pillar strength theory and pillar cross-sectional area load theory, and small deformation plate theory of elasticity, we apply the orthogonal sensitivity analysis method to analyze the stability influence factors of backfilling stope pillar and roof theoretically, so that we can figure out how much each influence factor could influence the pillar and the roof stability influence size. It concluded that pillar width and thickness of top plate is the biggest influence factor for stability of pillar and the roof respectively.关键词
