[0002] The coal mine coal conveying laneway usually adopts the belt conveyor with continuous transportation characteristics as the raw coal main transportation line equipment, due to the raw coal being transported from the upper belt conveyor to the lower belt conveyor, different intensity induced air flow is generated, and the air flow and the shear air flow at the inlet of the material guide groove jointly act on the coal body, which can cause the fine coal dust particles attached to the coal body to fall off, form coal dust particle flow, and the coal dust particles can flow into the material guide groove of the lower belt conveyor with the air flow and escape from the poor sealing soft connection, forming coal dust. In addition, the high-speed moving belt can drag the surrounding air to form a high-speed air flow, and the raw coal flow at the coal outlet and the high-speed air flow have a speed difference, which can further aggravate the coal dust diffusion problem in the U-shaped groove of the belt. Moreover, in order to facilitate maintenance and facilitate heat dissipation, a dust cover is not arranged at the tail of the belt conveyor, the residual coal dust at the tail of the belt conveyor can generate kinetic energy with the movement of the belt conveyor, and the coal dust can be thrown out of the tail, affected by the air flow, and spread everywhere, causing a large amount of coal dust pollution. The coal flow in the process of transloading, due to the height difference between the front and rear two conveyors at the lap joint, the dust generated in the process of coal flow falling. These coal dusts gather in the laneway, which can cause low visibility in the laneway, poor environmental quality, and great safety hazards, and seriously threaten the health of the coal mining personnel.
