Abstract: A material sampling and analyzing assembly comprises a material sampling device and a material analyzer assembly. The material sampling device is configured to extract a core sample of material from a supply of material. The material analyzer assembly is attached to a portion of the material sampling device. The material analyzer assembly comprises a first material analyzer configured to analyze a first testing sample, which comprises a first portion of the core sample. An alternate material sampling an analyzing assembly comprises a material sampling device comprising a discharge chute and a material analyzer assembly comprising a sample container and a material analyzer. The sample container is attached to the discharge chute. The sample container is configured to receive and temporarily retain a testing sample that is discharged from the discharge chute. The material analyzer is configured to analyze the testing sample while it is retained by the sample container.

Abstract: A coal haulage apparatus is provided for use in moving coal fragments within the horizontal shafts of a coal mine on a belt conveyor that runs longitudinally along the apparatus. The apparatus is an assembly of multiple, like sections that each have a pair of longitudinal rails and cross members which join the rails together in a parallel, spaced-apart relationship, of which the rails are designed to receive the bottom portion of V-grooved wheels of a dolly that can move longitudinally along the top of each section of the coal haulage apparatus. The longitudinal rails essentially act as the frame that supports the vertical weight of the dolly which rolls along the top of each section of the coal haulage apparatus, and a separate vertical support frame is not required. The rails are made of square tubing that uses a smaller mating, connecting tube to join rails from one section to another adjacent section.
