Abstract: Taking the goaf of industrial site of Shenghai Coal Mine as the research object, through data collection, geological
survey and on-site survey, the basic situation of the goaf of industrial site of Shenghai Coal Mine has been investigated, and the
scope of the goaf was inferred through geophysical prospecting. Then the drilling verification was carried out. Finally, this paper
evaluated the stability of the goaf qualitatively and quantitatively, and obtained the change law of stress and displacement during
the formation of the goaf through numerical simulation.

Key words: room and pillar type; stability; evaluation; numerical simulation
