DESIGNING ROADHEADER CUTTING HEADS

Boom roadheaders are tackling ever harder rocks where the design of their rotary cutting heads is crucial to successful operation. This paper summarizes early results of research at the Mining Research & Development Establishment into cutting heads and explains the general principles upon which they should be designed. One of the main conclusions is that the number of tools in a cutting line should not exceed half the number of cutting sequences (or starts), i.e. tools should not cut successively in the same lines. This is important for effective cutting in harder rocks. Computer programs have been developed to assist in the design of cutting heads; these are also briefly described. (Author/TRRL)
