Our range of mechanical cutting equipment includes electrically powered and trackmounted bolter miners for constructing and securing roadways, continuous miners and borer miners for continuous extraction of coal and soft minerals, boxhole borers for boring circular passages, reef miners for lowprofile mining, roadheaders for underground excavation and tunneling, and cutting attachments for ...
CONTINUOUS haulage in Australia''s underground coal mines is gathering momentum. With one system already up and running in Queensland and another by a different manufacturer about to be installed in New South Wales, it seems coal companies are warming to the technology.
The initial application of REMS involves underground coal mining, specifically roomandpillar type methods. Currently, we are integrating the extraction and haulage processes so that the coal can be properly loaded from the continuous mining machine into the continuous haulage .
For the industrial minerals market, we offer a full range of entry development equipment, including heavyduty continuous miners, continuous and batch haulage systems, and a wide range of feeder breakers.
Premron''s Continuous Haulage System (CHS) project, meanwhile, will revolutionise coal mining in underground mines, according to METS Ignited. It eliminates the use of shuttle cars, used to take the coal cut from the wall of the mine to a transfer point further away in the mine (dead time).

address the integration of mining and continuous haulage systems are also highlighted. That background is employed in devising a conceptual mining system for the underground mining of coal seams in the 14 to 28 inch range of thickness. Most of the equipment suggested for this proposed system is already available.
However, ever since the introduction of continuous miners in the late 1940s, roomandpillar continuous mining has been gaining ground over conventional roomandpillar mining. In recent years, roomandpillar continuous mining accounts for more than 38 percent of the underground coal production . Roomandpillar retreat mining currently ...
