Numerical modelling approach for estimation of a yield zone in the face of a deep longwall panel
Abstract In the Longwall mining method, the coal face is being supported with two-legged or four-legged shield supports which improve better roof control between the face and canopy tip. The development of load on the face increases with the face retreating rate or the increase of the overhung lengt...
