Research on Linkage Control of Coal Mining Machine and Scraper Conveyor
The amount of gas gushing out of the mining face is closely related to the advancement speed of the mining face,in order to reduce the impact of gas on coal mining and realise the uninterrupted mining of coal on the mining face,and to improve the effect of linkage control between the coal miner and scraper conveyor,a linkage control system of coal miner and scraper conveyor is constructed on the basis of the concentration of gas on the mining face.Through the theoretical analysis of coal mining machine,scraper conveyor on the coal mining machine gas outflow analysis and build coal mining machine,scraper conveyor and gas linkage control scheme;then based on the gas outflow control as the core construction of coal mining machine and scraper conveyor linkage control scheme,specifically combined with the change of gas concentration to adjust the operation of the coal mining machine and scraper conveyor,and at the same time based on the load of the scraper conveyor to regulate the hauling speed of the coal mining machine.After the application in 3705 comprehensive mining face project,the linkage control system can run smoothly,realise the continuous mining of coal and avoid the gas overlimit in the mining face.
