Performance Evaluation of Different Pick Layouts on Bolter Miner Cutting Head

Resumo

A bolter miner is a mining machinery of coal–rock cutting. In order to study the best pick layout of bolter miner cutting head, three kinds of pick layouts were designed. The performance evaluation of cutting head 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.
