Analysis on the Surface Subsidence Regular about Paste Filling Mining under the Buildings

In order to extend the life of enterprise, solve conflicts about mine connection and promote the sustainable development of coal enterprise, paste filling is adapt to the mine under buildings in Jiaozuo coal group zhucun and the observation station of ground movement is laid out. Through the analysis of observational data, the regular of the movement and deformation of the surface is found under the geological and mining conditions, which provides the technical basis for coal mining under other similar conditions. It has the important theoretical value and practical significance.
