In order to achieve efficient coal mining and transport at the mining face,and to ensure the coordinated and economic operation of scraper conveyor and coal mining machine,S7-300 PLC,sensors,Mesh network and WinCC are used to build a cooperative control system for the running speed of scraper conveyor and coal mining machine.The system architecture,sensor type,mesh network arrangement and WinCC platform control scheme are described and applied in 12303 comprehensive mining face.The results show that the operating speed cooperative control system can realise the cooperation between the chain speed of the scraper conveyor and the hauling speed of the coal miner,which can reduce the energy consumption of the scraper conveyor while meeting the high efficiency of coal production;at the same time,there is no coal pile-up of the scraper conveyor during the on-site application period,which makes the effect of on-site application more remarkable.
