【摘要】Coal mining under buildings certainly causes surface movement and deformation, therefore, it brings about deformation even fracture for buildings. It is an important task to evaluate correctly the buildings' damage grade caused by coal mining. Fuzzy comprehensive evaluation, considering some factors of buildings' fracture, has been applied to analyze the masonry structure buildings' damage grade after coal mining in this paper. It provides a scientific basis for buildings' reinforcement before mining and maintenance or compensation after mining.
