Analytical solution of predicting rib spalling depth of fully-mechanized coal working face based on tri-linear strain softening model
In order to predict rib spalling depth in fully-mechanized mining faces, taking the coal wall as the research object, the coal wall is regarded as a tri-linear strain softening material. Then the direct roof and main roof are taken as macro roof, and the bearing mechanical model for the interaction...
