Abstract In the actual use of EBZ-135 cantilever roadheader in Xinshun Coal Industry, the pick damage is frequent, which affects the safe and efficient production. In response to this problem. The finite element analysis of the cutting part of EBZ-135 cantilever roadheader in this mine is carried out. The pick model of roadheader is constructed by ANSYS software. Starting from the two working conditions of cross cutting and drilling, the force of cutting head is simulated and analyzed, and the pick design is optimized accordingly. After the implementation of the optimization scheme, the force effect of the cutting head is improved, and the difference of the combined external force between all picks is reduced, which is conducive to improving the efficiency and quality of the whole coal mine cutting operation.
