Abstract: The development and sustainability of intensive coal mines are restricted seriously by the coal mining under villages，which needed to be addressed.The current method is to relocate the involved villages，but there are some disadvantages such as high cost，lack of land and the residents′ reluctance to move.Therefore，reconstruction of the villagers′ houses before mining in the would-be subsidence area serves as a new way to prevent the coal mining under villages.In Xiaojihan Coal Mine，the observation of building anti-deformation and surface movement are made respectively in the testing building and the observation stations in order to make experimental study on the mining effect and mining without relocation.The result shows that the villagers′ houses with anti-deformation structure could be resistant to the mining influence.It is feasible to make mining without relocation in the mining area with good application value.

Key words: Anti-deformation testing building, Building formation observation, Mining without relocation, Surface movement observation
