摘要
Ocean University of China,QIdao,266071; 3.I.laoningTechnlcalUnlversity,Fuxin,123000) as serious damage of buildings, waterbodles,.ultlvated lands, railways, bridges caused by land subsidence, bed separation gtouting techno]Ogy of overburden Is put forward. To provide theoretical support for the technology, the charactenstlcs and the mechanics mechanism of mining overbuHen from layer--split to formation of bed separation are studied. On the basis of elastic sheet board theory, calculation formula of rocksheet deflection Is presented, and the mechanics crlterla Of the seParation forma- tion and the calculation fonllula of bed separation volume are set up. hnally, the applications and technics of bed separatlor grout technology of mining overburden to control land subsidence In china are Introduced.
