1. Coal mining technology-the methods and equipment used in each process of the coal mining face and their coordination in time and space.
2. Coal mining system-the layout of mining roadways and their mutual positional relationship in time and space.
3. Coal mining method-integration of coal mining technology and coal mining system. Stope-a place used to directly take a large amount of coal
4. Coal mining face---the coal wall for stoping in the stope
5. Classification of coal mining methods according to the angle of inclination, near-horizontal coal seam mining, gently inclined coal seam mining, inclined coal seam mining, steeply inclined coal seam mining, thin by thickness, and medium thick coal seam mining, thick seam mining (divided into Seam mining and whole seam mining (fully mechanized caving, large mining height)) According to the mining technology classification, blasting mining method, ordinary mechanized coal mining method, comprehensive mechanized coal mining method
Classification according to the direction of advancing Strike longwall coal mining method Inclined longwall coal mining method (downward and upward) is classified according to the goaf treatment method
Caving mining method Knife pillar (coal pillar support) method Filling coal mining method
6. Wall-type coal mining method 1) Single long arm mining method for thin and medium thick coal seams Single strike long arm caving mining method (single long arm mining method) Single long arm knife pillar mining method (coal roof Extremely hard) Long arm mining with a single pseudo-inclined strike (steep coal seam) 2) The mining method of thick seam slicing is divided into thick seam slicing methods: inclined layering, horizontal layering, inclined layering, inclined layering— The thick coal seam is divided into several layers parallel to the coal seam layer, and then mined layer by layer. Horizontal layering—The thick coal seam is divided into several layers parallel to the horizontal plane, and then mined layer by layer. Oblique cut layering—The thick coal seam is divided into several layers at a certain angle to the horizontal, and then mined layer by layer. 3) Coal mining method for thick coal seam mining
7. The general characteristics of wall-type coal mining method: long working face, 80-250m; at both ends of the working face, there is generally at least one mining roadway; generally the roof exposed area is large, and the pressure of the mine is relatively strong; coal is transported on the working face The scraper conveyor is parallel to the working surface
8. Pillar system mining method room mining method room and pillar mining method
