Development and application of coal sliding plate device between shelves in fully-mechanized caving face
The mining method of Pulongwan Coal Industry is top coal caving mining.During the normal production period of the working face,a large amount of floating coal between the shelves is generated after the shelves are moved,mainly formed by the falling coal blocks from the gaps between the shelves.To address this issue,a device has been developed that can collect coal that falls from the gap between support frames through a U-shaped coal chute and finally slide it into a scraper conveyor.In practical production applications,95％of the inter rack coal falls into the scraper conveyor through this device,without affecting the coal cutting of the unit,greatly reduc-ing the labor intensity of workers and improving labor efficiency.
