Based on the principle of similar simulation, through laterally pushing on the gangue bulk, the influence of discharge step distance, pushing force, water content and loess content on the compaction characteristics of the filled gangue under the limited roof was analyzed. Experimental results show that the increase of discharge step distance is not conducive to the consolidation of gangue; Pushing force increases contributing to the consolidation of gangue, pushing force 1.25 KN is the inflection point for the increasing of rest angle and the slowing of volume change rate; The water content has a significant effect on the consolidation characteristics of the gangue under lateral pushing. Loess content has the most significant effect on consolidation of gangue bulk under the lateral pushing.
