Coal retaining plates are mainly used for blast mining of thin coal seams. The coal retaining plate is composed of one coal retaining plate, two coal retaining plates and their height-adjusting connectors. Its structure includes a coal retaining plate and a connecting piece that connects the lower part of the coal retaining plate to the side of the working surface scraper conveyor chute close to the goaf area. It is characterized in that the coal retaining plate consists of a first coal retaining plate and a second baffle. The coal boards are connected to form one coal retaining board at the bottom, the lower part of which is fixedly connected to the chute. The second coal retaining board is added to the top. The first coal retaining board is on the side of the goaf area, and its top is close to the roof. The first coal retaining board and the second coal retaining board are There are several unloading holes distributed on the board, both of which are connected by height-adjusting connectors passing through the unloading holes. One coal baffle is at the bottom and its lower part is fixedly connected to the scraper conveyor chute on the working face. The second coal baffle is on the side of the goaf. The first coal baffle is on the goaf. The top of the coal baffle is close to the roof. There are a number of unloading holes distributed on the first and second gear baffles, both of which are connected by height-adjusting connectors that pass through the unloading holes. Height-adjusting joints can use anchor chains and locking plates. The coal retaining plate is height-adjustable and simple, and can adapt to changes in mining height of the working face and has good coal retaining effect.
The improved coal retaining effect increases the recovery rate of floating coal, reduces the loss of resources, reduces the labor intensity of workers, shortens the coal extraction time, and reduces the cleaning of floating coal to a row of piers, reduces accidents of roof collapse and injuries, and reduces damage to hydraulic support equipment caused by blasting. The structure is simple, the materials are easy to install, the operation is simple and easy to replace, and no extra labor is added to the workers.
