The continuous surface miner is a modular machine that operates by using a rotating cutting drum fitted with cutting tools to cut material from rock formations in layers. As the crawler-mounted machine moves forward, the cutting drum rotates against the direction of travel to cut the material. The cutting tools transport the mined material toward the center of the drum where it can then be loaded onto conveyors. The mined materials can be directly loaded onto trucks, discharged to the side to be mixed, or deposited as a windrow between the miner's crawler tracks.

1. The continuous surface miner

6. Construction
• It has a crawler mounted machine having cutting drum centrally
mounted beneath the machine at the front end of the same .
• The cutting drum has helix van over which tungsten carbide tipped
cutting bits are mounted.
• A shield (clow) is fitted behind the cutting drum
• By virtue of rotation of the cutting drum the material is cut ,crushed
between the helix and cowl and then they are conveyed from two
side of the drum to the centre of the same ,from which material is
pass through an intake channel in the shield into the primary
conveyor 9loading conveyor) behind it
• Then the material in turn transfer on to discharge belt conveyor
• The drum is operated by pole changing squirrel cage induction
motor and can be raised ,lowered and tilted by hydraulic ram
• The frame work of continuous miner is rigid welded box with
integrated tanks for diesel, water, hydraulic oil

Basic elements of continuous surface miner

13. continuous surface miner
• Such machine operates on the principle of rock cutting by rotary picks. The
cutting force is provided by the rotary motion of the cutting drum and the
propelling motion of the CSM. As the crawler mounted machine moves
forward, the rotating cutting drum fitted with cutting tools rotates against
the direction of the travel and cuts material from the rock formations in
individual layers.
• The cutting tools are so arranged on the drum that it ensures transportation
of the mined material towards the centre of the cutting drum from where it
can then be loaded via the primary and discharge conveyors, as
required. The cut or mined materials are managed in the following ways:
• Direct loading permits the mined material to be transported to trucks or
dumpers via a height adjustable and slewing conveyor system.
• Discharging the mined material to the side enables it to be mixed for
specific purposes.
• Depositing the material as a windrow between the miner’s crawler tracks is
also an option.
