In these mining systems, a continuous miner or an auger machine is primarily used to extract coal from the highwalls.
He stood with a remote control panel in his hands, operating a machine called a continuous miner that was clawing into the coal seam and dumping load after load into the shuttle cars lined up in the tunnel behind him.
Some things about what happened in the mine were known — where the men were, for example, just after 2 45 a.m. on Monday, operating a machine called a continuous miner that paws the coal face.
The former consists of a continuous miner, addcars (belt conveyor cars), a launch vehicle, a stacker conveyor and a loader as shown in Fig. 2.
This system consists of a continuous miner, double auger flights, a stacker conveyor and a front-end loader basically as shown in Fig. 5.
The latter consists of a continuous miner, archveyor chain conveyor that conveys coal and trams the machine system itself, and a loadout vehicle as shown in Fig. 3.
Typical pressure bursts occur while a continuous miner is extracting a pillar or a longwall shearer is cutting the tailgate corner of the face.
The results have concluded that conventional manual handling practices on a continuous miner can be eliminated, and that the prototypes have significantly reduced the technical risk in proceeding to a full underground trial.
Formation of an irregular shaped rib/snook during MD of the existing square/rectangular pillars by a continuous miner and uniqueness of the existing geo-mining conditions also limit scope of application of the conventional rib/snook design approaches.
At the University of Wollongong a series of reprogrammable electromechanical manipulators have been designed to overcome these challenges and automatically handle the installation of roof and rib containment consumables on a continuous miner.
