Shovel loading resistance is the reaction force of the material on the bucket during the shovel loading process, which contains two parts: the resistance of the bucket insertion stage and the resistance of the lifting stage. The resistance of shovel loading has a great influence on the loading efficiency, so it is important to carry out resistance research. Based on the discrete element theory, this paper applies EDEM software to establish a simulation model of the loading process and realise the simulation of the forward and reverse shovel loading process. Through the simulation, the mechanical characteristics of the shovelling operation are visually analysed, and the obstructing effect of the material on the bucket is clarified; the shovelling resistance of the key parts of the bucket at different stages of the shovelling process is specifically analysed, and the parts where the peak shovelling resistance is located and the stages where it is located are identified. The influence of the shovel angle on the resistance is also analysed.
