Overview

The HW300 produces high volumes of coal at very low costs. More importantly, it is safer than traditional underground mining, as it sends no one underground, and it works economically with a small crew and very little support equipment. It’s versatile in its mobility and application, and it produces large quantities of coal at inherent ash levels. When you need to improve the recovery of your coal reserves, consider the Highwall Miner – consider the HW300.

Water Consumption

System A closed loop cooling system, alleviates the need for water to cool the machine. In applications where water is necessary for cutting, a cutter module spray option is available. Water consumption during the mining operation is an average of 1000 L (264 gal) per hour (estimate). A closed loop cooling system, alleviates the need for water to cool the machine.

HW300 Optional Equipment

GAMMA DETECTION SYSTEM
  • Used to assist the operator as the cutter module is guided through the coal seam, leaving predetermined amounts of coal in the roof and floor. This system also allows the mining of coal in soft roof and/or soft floor situations.

ARCTIC PACKAGE
  • For extreme-cold climates, this package extends the operating temperature to –40° C (–40° F).

RIGHT-ANGLE DISCHARGE
  • This feature discharges coal to the right or left of the machine.

PUSH BEAM GRAPPLE
  • This tool is available from the Cat dealer and mounts to the front of a wheel loader to provide safe and efficient transportation of push beams to and from the highwall mining system.

GENERATOR SET
  • A self-contained generator system is an option that can be sourced from the local Cat dealer. It provides electrical power to the highwall mining system in remote locations where connection to a utility grid is not practical.
