And this has many disadvantages and hazards. It takes a lot of extra energy to lift the gangue from the underground; it also consumes a lot of resources in the coal washing process; and the separated coal gangue not only wastes land resources, but also spontaneous combustion, rain, and mud serious harm to the environment

Embodiment Construction

[0054] like figure 1 As shown, the present invention includes a horizontal constant speed belt conveyor and an inclined high speed belt conveyor. Among them, the horizontal constant-speed belt conveyor 2 transports the raw coal 1 from the working face. When the raw coal 1 moves to the right to the material outlet 3 of the horizontal constant-speed belt conveyor, it will fall; the inclined high-speed belt conveyor 4 is located under the horizontal constant-speed belt conveyor 2. When the raw coal 1 falls on the inclined high-speed belt conveyor 4, it will slide relative to the conveyor belt. acceleration. Due to the different coefficients of friction between coal, gangue and the conveyor belt, the frictional force along the conveyor belt is different for the two, so the acceleration of the two is also different; At the material outlet of the conveyor, coal and gangue have different speeds; in the next moment, both coal and gangue will do oblique throwing motion. However, be...

Abstract

The invention provides a method and a device for separating coal and gangue by using a high-speed belt conveyor underground. The device mainly includes two belt conveyors, one of which is a belt conveyor running at normal speed, which mainly transports coal and gangue from the working face; the other is a belt conveyor running at high speed, whose main purpose is It is to accelerate coal and gangue. The new device for separating coal and gangue proposed in this experiment has the advantages of easy installation, simple structure, safe and reliable operation, and small space.

Description

technical field [0001] The invention relates to a device for separating coal and gangue in underground mines, which can be directly applied to the device for separating coal and gangue in underground mines. Background technique [0002] In the process of coal mining, a large amount of gangue is contained in the mined coal due to the mixing of a large amount of gangue in the roof and bottom plates and in the coal seam. These coals cannot be used directly and need to be treated by gangue removal. [0003] In the traditional coal mining process, the treatment method for the coal containing coal gangue is to be screened by the coal preparation plant after being transported out of the ground. And this has many disadvantages and hazards. It takes a lot of extra energy to lift the gangue from the well; it also consumes a lot of resources in the process of coal washing; and the separated coal gangue not only wastes land resources, but also causes spontaneous combustion, rain, mud, ...
