ABSTRACT
Aiming at the problem that the cutting efficiency of a drum shearer is low when mining
hard coal seams, an experimental bench of high-pressure water fracturing assisted cutting
is designed. Compared with normal ones, the maximum equivalent stress of the improved
experimental bench is reduced by 55.38%, and the maximum total deformation is reduced
by 27.23%. According to the results of dynamic response analysis, it is concluded that the
experimental bench of high-pressure water fracturing assisted cutting is stable and reliable
under extreme working conditions, and meets design requirements for strength and stiffness.
