Coal mining - Wikipedia
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is
Glossary of Mining Terms - Coal Education
A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
Conveyor Capacity - Engineering ToolBox
Conveyor capacity is determined by the belt speed, width and the angle of the belt - and can be expressed as. Q = ρ A v (1) where . Q = conveyor capacity (kg/s, lb/s) ρ = density of transported material (kg/m 3, lb/ft 3) A = cross-sectional area of the bulk solid on the belt (m 2, ft 2)
Conveyor belt - Wikipedia
A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems.A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are
Limestone - Official Satisfactory Wiki
Limestone is a basic type of ore which is abundant in the world. It is primarily used to produce Concrete, an essential material in factory construction. Limestone can be harvested by hand (default E) in trace amounts from resource deposits scattered across the world, or from inexhaustible resource nodes on which Miners can be constructed to extract automatically.

Conveyor Belt - Official Satisfactory Wiki
Conveyor Belts are structures used to transport items between buildings. They come in five marks with different building costs, throughput, and appearance. Conveyor Belts can only be built between building connection ports or Conveyor Poles. Once a Conveyor Belt is connected to a building's output (such as a Miner), it will begin to pull items out from the building's output slot.
