Abstract
A mining apparatus includes a frame, a mechanism for cutting an arched opening in a seam and winning the cut mineral, and a propulsion system. The cutting mechanism includes a boom supported mineral cutting drum having a barrel or bulging cylindrical shape. The propulsion system is canted on the frame at an angle from the horizontal in order to match the floor of the arched opening being cut by the drum.
Claims18
An apparatus for mining mineral from a seam, comprising:
- a frame;
- means for cutting an opening in the seam and winning mineral from the seam mounted to said frame, said cutting and winning means including a mineral cutting drum having a midline of greatest diameter gradually tapering toward opposed ends providing a radius of curvature of between 150-500 inches for cutting an opening including a substantially continuously arched roof and floor defined between two sidewalls;
- and
- means for propelling said apparatus, said propelling means being mounted to said frame.
An apparatus for mining mineral from a seam comprising:
- a frame:
- and
- a rotary drum mounted to said frame for cutting mineral from the seam, said rotary drum having an arched profile and including a midline of greatest diameter gradually tapering toward lateral ends of said drum so as to provide a radius of curvature of between substantially 150-500 inches.
An apparatus for mining mineral from a seam, comprising
- a frame;
- means for cutting an arched opening in and winning mineral from the seam, said cutting and winning means being mounted to said frame, said cutting and winning means further comprising;
- (A) a mineral cutting drum having a midline of greatest diameter gradually tapering toward opposite ends providing a radius of curvature of between 150-500 inches;
- (B) a boom pivotally mounted to said frame for operatively supporting said mineral cutting drum;
- and
- (C) a loading shovel connected to said frame and underlying said mineral cutting drum, said loading shovel including an arched floor pan substantially corresponding in contour to said mineral cutting drum;
- and
- means for propelling said apparatus, said propelling means being mounted to said frame.
An apparatus for mining mineral from a seam comprising:
- a frame;
- a cutter that is contoured for cutting an arched opening in and winning material from the seam, said cutter being mounted to said frame;
- a loading shovel connected to said frame and underlying said cutter, said loading shovel including an arched floor pan substantially corresponding in contour to said cutter;
- and
- means for propelling said apparatus, said propelling means being mounted to said frame.
