Analysis on Catastrophe Theory During First Weighting Sliding Instability and Support Crushing of Main Roof with Large Mining Height in Shallow Coal Seam
Roof sliding and instability along the coal wall usually occur in the working face at large mining heights during the process of the first weighting, which causes roof cutting and support crushing. A mechanical model consists of the main roof, immediate roof, and support based on the nonlinear chara...
