Equivalent materials simulation experimental study on bed separations developing and mining subsidence in constant humidity and constant temperature conditions

A new experiment was made on the developing of bed separations and mining subsidence from Tangshan T2192 working face by equivalent materials simulation. The overburden deformation and the developing of bed separations with working face advancing was simulated by a new model. The results show that t...

Summary:A new experiment was made on the developing of bed separations and mining subsidence from Tangshan T2192 working face by equivalent materials simulation. The overburden deformation and the developing of bed separations with working face advancing was simulated by a new model. The results show that the maximum value of bed separations moved forward gradually along with the working face advancing; the maximum value of bed separations is 0.31-0.50 times of mining thickness. The key strata have a great influence upon surface subsidence during the overburden movement process. The mechanics parameters of new experiment are fitted with results in fields perfectly.
