Research and development of electromechanical control system for continuous shearer and application

The continuous shearers in use by Shendong Coal Group are mainly produced by JOY Co., Ltd. Due to the long serve time, there are many problems in the electronic control system. Through analysis and research of the working principle, protection logic, system function, structure characteristics of the electric control box shell, internal layout mode and spare parts characteristics of the electronic control system of the imported continuous shearer machine, electronic control system is completely selected and designed independently, and it is applied on 12CM15 continuous shearer, good results have been achieved. It is gradually spread to other extractive equipment.
