Modular Pick-and-Bucket Mining MachineConcept for improved conventional pick-and-bucket mining machine offered as backup for hydrojet-jaw mining machine. Picks on chain dislodge coal and buckets on chain scoop it up. Depending on width cut, unit composed of only two end modules or end modules plus one, two, or three incremental modules. Folding curved shields protect sides of miner from falling coal and rock. Two side stabilizers - extendable hydraulic members - anchor miner against lateral drift. Unlike conventional machines, new version tilts cutters vertically and skews them horizontally to changing floor slopes and seam heights.
