Abstract: An auger support assembly for use with an augering system for mining which bores a pair of side-by-side holes through a coal seam using dual side-by-side augers. Each auger includes a drilling section which is followed by a series of auger flights for conveying the bored coal back out of the respective hole. The augers are connected together in axially aligned pairs and are supported by the auger support assembly. The auger support assembly includes a pair of bearing housings that are disposed on drive shafts which extend outwardly from the first ends of a first pair of parallel augers and are received within the second ends of a second pair of parallel augers. The bearing housings are connected to each other by a tie bar. A single support leg extends downwardly from approximately the mid-section of the tie bar to engage the ground ledge that is formed between the counter rotating augers.

Abstract: A system for removing clean coal from raw coal without the use of water includes a vibratory separator which receives the raw coal and a supply of magnetic particles. The magnetic particles form a fluidized bed which floats the clean coal from the debris contained in the raw coal and removes the clean coal by a scraper plate. A mixture of debris and magnetic particles which remains after the clean coal is removed is passed by a revolving magnetic separator which removes the magnetic particles from the debris and from the clean coal, and returns the particles for reuse with another batch of raw coal. The magnetic separator includes a rotating drum having a non-magnetic outer surface and an interior magnet which forms a magnetic field adjacent a portion of the drum surface which temporarily attracts the magnetic particles which fall from the drum surface as that portion of the drum surface and collected particles pass beyond the adjacent magnet.

Abstract: An auger flight support for use with an augering system for mining which bores a pair of side-by-side holes through a coal seam using respective augers. Each auger includes a drilling section which is followed by a series of auger flights for conveying the bored coal back out of the respective hole. The auger flight support includes a bearing housing that connects axially adjacent auger flights together, adjacent bearing housings in the side-by-side augers are connected by a tie bar. A support leg extending downwardly from approximately the mid-section of the tie bar to engage the ground ledge that is formed between the counter rotating augers.

Abstract: An auger flight support for use with an augering systems for mining which bores a pair of side-by-side holes through the coal seam using respective augers. Each auger includes a drilling section which is followed by a series of auger flights for conveying the bored coal back out of the respective hole. The auger flight support includes a pair of thrust bearing and housing assemblies which are tied together and each supported by a respective leg which lowers the friction between the auger flight and the bottom of the bore. This significantly reduces the power required to rotate the augers.
