Stacking method and system of stacker-reclaimer

The invention discloses a stacking method and system of a stacker-reclaimer. The stacking method comprises the steps that the current pitch angle of a cantilever when a working material machine works on a current stacking large layer is obtained; the stacking position point of the working material machine when the front stacking unit block works and the current-layer arm-rail included angle range between a cantilever and a rail are obtained; the current material flow real-time volume flow of the feeding belt is obtained; a current real-time arm-rail included angle between a cantilever and a rail when the working material machine works on the current unit block stacking small layer of the current stacking unit block is obtained; the theoretical material height of the bottom bearing layer of the current large stacking layer is obtained, and the actual material height of the bottom bearing part at the current real-time arm rail included angle position of the current small stacking layer of the unit block is obta
