Popis:	A method of cutting coal with three drums was advanced, a three-drum shearer was designed, and the free mode and restrained model under prestress of the third drum were analyzed in large mining with ANSYS Workbench 14.0 to solve the damage problem of the cutting blade in a large mining face. The vibration modes caused by its own structural characteristics are obtained, and the dynamic response of all parts of the shearer is studied with MATLAB R2016a software under given conditions and the change of the parameters. The overloads of the front drum give rise to larger vibration displacements that should be avoided in the operation of the shearer. The above approach is of importance to evolve the design concepts and improve cutting characteristics of the largeheight shearer, to provide theoretical backgrounds ensuring safe and reliable mining of superthick coal seams by the large-height shearer.
