AB - In this paper, a numerical calculation model of the mining face was  established to analyze the rational size of coal pillars in the goaf on both  sides by using FLAC3D based on the mining geological conditions in the pilot  area. Furthermore, the feasibility of co-ordinated reinforcement with steel  pipe column was explored, which can be applied to the recycling of residual  coal resources like protecting coal pillars and of great value to increase  the recovery rate in gobs as well.
