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

摘要: 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 with advancing simulated a model. results show that maximum value moved forward gradually along advancing; is 0.31∼0.50 times thickness. key strata have great influence upon surface during movement process. mechanics parameters are fitted in fields perfectly.
