Abstract：To study the rock breaking performance of the integrated excavator and anchor under different factors and optimize the structure,a rock breaking model of the cutting disc was established using discrete element EDEM software.Three different structures of cutting discs were simulated to obtain the three-dimensional load and fluctuation coefficient of the cutting disc,in order to evaluate the cutting performance of the cutting disc and study the influence of the cutting disc structure on the cutting performance.Research has shown that under the two cutting methods of vertical top-down and horizontal propulsion,the cutting load characteristics of the three types of cutters are similar,and the load of the toothed cutter is smaller,proving that the toothed cutter has good rock breaking ability.Under the two cutting methods of vertical top-down and horizontal advancement,the load fluctuation coefficient characteristics of the three cutting discs are similar,and the load fluctuation coefficient of the disc-shaped cutting disc is smaller,indicating that the disc-shaped cutting disc produces less vibration on the cutting part.When evaluating the cutting performance of the disc,the cutting load should be given priority,followed by the load fluctuation coefficient.The research results showed that the tooth shaped cutting disc had better rock breaking ability,and the optimization of the cutting disc structure could further reduce the impact of rock ridges on the whole machine.This study can provide a certain reference basis for the actual mining process underground and the design of cutting discs for integrated mining and anchoring machines.
