Abstract: Macromechanics analysis of X-type shearing failure, shearing-failure, drumming slope-split leather-fracture damage were done on stability of backfill of deep stope of copper mine in Anqing city through deformation phenomenon of backfill, different depth monitoring was done by using inclinometer, analysis model of overall stability of backfill was established by adopted Mohr Criterion, collapse laws of X type shearing, shear type, drumming slope-split leather-fracture occurred at partial slope wall of backfill were obtained.Analysis results indicate that different height of the filling body stability exposure need to meet the condition of minimum normal stress value, while it has important guiding significance for backfill strength plan making.

Key words: Cemented filling body, Macromechanics, Inclinometer, Mohr criterion, Stability
