Definitions

  • FIG. 1 is a schematic plan view illustrating a mining machine including a scraper conveyor and a cutting apparatus disposed along the working face of a seam;
  • each casing section includes a front wall in the form of an angular plate 7 having an attaching portion 7a at the lower end thereof which is slanted at the same angle as the rear wall Ia of the respective channel section I, and abuts the same.
  • the upper portion of the angular plate 7 is vertical.
  • a horizontal cover or top wall 8 is welded to the upper plate portion and rearwardly projects from the same above the space in which the upper run of chain 6 is located.
  • a guide casing structure having guide casing sections coextensive with said channel sections, respectively, each casing section comprising a casing front wall having a lower portion secured to said rear wall of the respective coextensive channel section and having a bottom edge located above the level of said bottom surface; a top wall secured to said front wall rearward projecting above said upper run; rearward projecting carrier brackets secured to said casing front wall between said upper and lower runs; a casing rear wall detachably secured to said carrier brackets and to said top wall so that said casing front and rear walls are located on opposite sides of said chain means; and parallel front and rear guide rails secured to the lower portions of said casing front and rear walls, respectively, and having rectangular cross sections, said
