Abstract
A bolter miner is a new type of mining machinery with cutting and anchoring functions. In order to study the best pick layout of bolter miner cutting head, three kinds of pick layouts were designed. The evaluation of the cutting head on the cutting performance under the condition of different rotational speeds and pick layouts was intensively studied by simulations and experiments. And the reality of the simulation is verified by cutting experiments. The aim of this research is to provide theoretical guidance for the design of bolter miner cutting head.
