PLC-based Coal Mining Machine and Scraper Conveyor Linkage Control Technology Research
In order to solve the shortage of serious gas protrusion problem in the mining process of high gas mines,a model of gas outflow is established by using quantitative theory,and a dynamic joint control technology of coal mining machine and scraper conveyor is established,which takes the gas outflow as a reference to achieve the collaborative regulation and control of the operating status of coal mining machine and scraper conveyor.According to the practical application,the new linkage control system can reduce the underground gas overlimit abnormality by 91.6％,reduce the scraper conveyor operation energy consumption by 22.6％,and effectively improve the safety of the integrated mining operation in the coal mine.
