Continuous mining machine

Continuous miners cut and gather the material simultaneously and convey it into shuttle cars, haul trucks or a continuous haulage system. They are typically used for full-scale production in room-and-pillar mining operations. The flameproof design of these machines is certified according to national regulations, such as MSHA (USA), SANS (South

The term continuous as applied to development machines has been one of the biggest misnomers used for mining equipment because, on development, they are usually anything but continuously cutting. The main delays mostly occur while roof support is installed and often waiting for shuttle cars to return from their discharge point for reloading

A mining machine for performing a continuous mining operation in hard rock. The operating portions of the machine are mounted on substantial deck sections hingedly connected to each other to promote maneuverability of the machine in confined spaces. A mining implement capable of breaking ore from the solid is mounted on a rotatable, extensible

Continuous mining machines with transverse cutting elements positioned in front of the mining machine are known. For example, in U.S. Pat. Nos. 2,695,164 and 3,310,247, a pair of boom members extend forwardly from the mining machine frame and have disc-like rotatable dislodging elements mounted thereon

A continuous mining machine comprising an elongated conveyor assembly for continuously conveying coal cut from a coal seam rearwardly away from the face of the coal seam being cut having a frame structure associated therewith. A power driven cutting assembly is disposed forwardly with respect to the frame structure for cutting coal from the

Mining3 developed the Oscillating Disc Cutter, which was licensed in 2006 by Joy Global (now Komatsu Mining Corp) and rebranded as DynaCut™. With relatively low input power, the DynaCut cutting technology – now incorporated into Komatsu’s DynaMiner machine – enables continuous, or semi-continuous mining of hard rock in both surface and underground applications

Jan 19, 2016 COAL MINE FATALITY --On Tuesday, January 19, 2016, a 36-year-old continuous mining machine operator was fatally injured when he was pinned between the conveyor boom of the remote controlled continuous mining machine and the coal rib while positioning the trailing cable. The victim had trammed the continuous mining machine back out of the No. 6 Face into the last open

Continuous miner: Mining machine designed to remove coal from the face and to load that coal into cars or conveyors. Cutting: Operation of making openings across a coal seam. Cutting drum: Rotating drum with carbide teeth that cuts the coal from the seam. Extended cut: Cutting an entry that is more than 20 ft long without stopping to support

A continuous mining machine includes a main frame mounted on tracks for mobility, a cutter head mounted on a subframe which is adapted to be moved toward and away from the front of the main frame, a conveyor to collect mined material and convey it to the rear of the main frame, and a roof bolter supported on the main frame adjacent the front thereof, whereby, as the sub-frame is moved away
