摘 要：To control land surface subsidence caused the underground mineral exploitation and the catastrophic phenomena suchas serious damage of buildings,waterbodies,cultivated lands,railways,bridges caused by land subsidence,bed separationgrouting technology of overburden is put *** provide theoretical support for the technology,the characteristics and themechanics mechanism of mining overburden from layer-split to formation of bed separation are *** the basis of elasticsheet board theory,calculation formula of rock sheet deflection is presented,and the mechanics criteria of the separation forma-tion and the calculation formula of bed separation volume are set ***,the applications and technics of bed separationgrout technology of mining overburden to control land subsidence in china are introduced.
