Abstract

This paper presents an analysis method of mining subsidence mechanisms of gob. The surface above gob appears displacement and deformation with the process of coal mining. The building foundation is affected seriously and the building is displaced, deformed and even destroyed. A plenty of data on the displacement and deformation is collected in Xinmi coalfield. By means of the data, the characteristics of the displacement and deformation and the effects on mining buildings are simulated with FLAC. After analysis, this paper gives the preventive measures of mining subsidence of gob and the protection measures of mining buildings.
