Underground Mining Applications

Hartline Supply can meet all your electrical cable needs for underground mining. This picture shows a continuous miner. It is operated by remote control so the operator can stay away from the machine and the unsupported roof.


This is a shuttle car. It is used to carry material from the continuous miner to the conveyor belt system, which carries the material to the surface of the underground mine.

This is a roof bolter. It is a machine that is used in an underground mine to install roof bolts. The bolts keep the mine safe by preventing the roof from caving in. It is a very important machine for underground mining.


The picture on the left and the picture below show two different views of an underground operating longwall system. It is comprised of a shear that moves back and forth along a pan line that can be several hundred feet long. It can mine greater amounts of coal in less time.
