Coupling Effect between Single Key Strata and the Overburden Thick Sandy Soil Layer
Through the simulation model test, coupling effect between single key strata and t overburden thick sandy soil layer is studied, failure character of thick sandy soil layer is obtained. Meanwhile, load transmitting law on the key strata(key block) is found. This discovery will make progress on dynamic roof structure theory.
