Research on subsidence rule of filling mining under buildings in Xingtai Coal Mine
ZHAO Xiao-jiang
Abstract：In order to protect the roadway,building,body of water and railway from the harmful effects of exploita-tion,and reduce waste of underground resources,the fully -mechanical technology of filling mining under buildings is used for mining under industrial squares in Xingtai Coal Mine for the first time.This paper introduces the main i-deas of the fully -mechanical technology of filling mining under buildings.A rock movement observation station is established for the 7606 filling working face,the rules and the predicted parameters of mining subsidence are sum-marized,and then the predicted parameters are validated through 7608 filling working face.The results show:the se-lection of the predicted moving parameters is reasonable with correct method,and the prediction results can reflect the deformation characteristics of surface movement in filling mining of gangue fly ash.
