• The 30MB3 miner is a radio-controlled drum-type continuous miner with appropriate weight balance, cutting and loading power to enable the productive mining of coal and other soft mineral in seams ranging from 1,900mm up to 4, 000mm thick.
• The machine is mounted on crawler tracks that provide full mobility and sharp turning radius in both bord and pillar and long wall development mining plans. The ranging cutting head mines material from the solid face using a chainless rotating drum, and a CLA-type gathering head with high speed conveyor efficiently moves mined material to a haulage system behind the miner.
• The machine’s weight and balance is designed to mine most efficiently by either sumping into the face at the top or bottom of the seam, and ripping material to the bottom or top of the seam.
• The above figure shows a general arrangement of major mechanical components. A full description of the various major sub-systems of the 30MB3 follows.
