Use of contionous miner

Question

Accepted Answer

A continuous miner is a machine used in mining operations to extract coal or other minerals from the earth.

A continuous miner is typically used in underground mining operations.
It is designed to cut and gather material in one continuous operation.
The machine has a rotating drum with cutting teeth that scrape coal or ore from the mine face.
The material is then loaded onto a conveyor belt for transport to the surface.
Continuous miners are highly efficient and can operate in tight spaces.
They are commonly used in coal mining but can also be used in other types of mining operations.

Accepted Answer

The angle of repose refers to the maximum angle at which a granular material, such as sand or gravel, can be piled up without slumping or collapsing. It's the steepest angle relative to the horizontal plane that the material can maintain stability. The angle of repose varies depending on factors such as the size, shape, and cohesion of the particles, as well as the presence of any moisture. It's an important concept in fields such as civil engineering, geology, and material science.
