Types of coal mining

1, open-pit mining

When the coal seam is close to the surface, it is more economical to use open-pit mining. The soil above the coal seam is called topsoil. Bury explosives in undeveloped topsoil area, and then use excavators, excavators, trucks and other equipment to remove topsoil. The topsoil was filled into the previously mined mine. After the topsoil is removed, the coal seam will be exposed; At this time, the coal is drilled or blasted, and the coal is transported to the coal preparation plant by truck for further treatment.

Open-pit mining can obtain a larger proportion of coal mines than underground mining because more mining areas are used. Open-pit coal mining can cover several square kilometers. About 40% of the coal mines in the world adopt open-pit mining.

2. Underground mining

Most coal seams are far from the surface, so it is impossible to use open-pit mining. Underground mining accounts for 60% of the world's coal production. The room column method is usually used to advance in the coal seam in the mine, and the mine is supported by beams and columns.
