Coal mining process five main processes

The five main processes of coal mining process are as follows:

The five main processes of coal mining process include: breaking coal, loading coal, transporting coal, supporting, and treating empty areas. The following is the detailed introduction of each process:

Coal Breaking: Coal breaking is the first process of coal mining, which mainly uses the coal mining machine or blasting method to cut the coal from the coal wall. In the process of breaking coal, you need to control the mining height to ensure the flatness of the coal wall and mining efficiency. At the same time, attention should also be paid to avoid excessive damage to the coal wall to reduce the waste of resources and safety hazards.

Coal loading: after breaking the coal, the coal needs to be loaded into the transportation tool. There are various ways of loading coal, such as bucket loading, conveyor belt loading and so on. In the process of loading coal, it is necessary to maintain the fullness of the transportation means, in order to improve the transportation efficiency of coal. At the same time, care should be taken to avoid overloading resulting in spillage or damage to the equipment.

Coal transportation: coal transportation is the process of transporting coal from the working face out of the mine. Commonly used methods of coal transportation include rail transportation, scraper conveyor transportation and so on. In the process of coal transportation, it is necessary to ensure the continuity and stability of transportation, to avoid the interruption of transportation leading to a decline in production efficiency.

Support: In the process of breaking coal and transporting coal, it is necessary to support the working face to maintain its stability and safety. Commonly used support methods are single pillar, hydraulic support and so on. In the process of support, you need to choose the appropriate support method and density according to the actual situation of the working face to ensure the stability and safety of the working face.

Handling of empty area: The empty area is the space left after coal mining, which needs to be handled in time to prevent the working face from collapsing and safety hazards. Commonly used methods of processing the hollow zone are collapse method, filling method and so on. In the process of processing of the mining airspace, it is necessary to choose the appropriate way according to the actual situation, in order to ensure the safety of production and the rational use of resources.

The above are the five main processes of coal mining process, each process is related to the efficiency and safety of coal mining, and needs to be strictly controlled and optimized. In actual production, it is also necessary to combine with the actual situation to make reasonable adjustments and optimization, in order to improve the efficiency and safety of coal mining.
