    A mining apparatus has a plurality of rail sections having longitudinally abutting rail-section ends each having a predetermined longitudinal rail-section length. These rail sections together form a longitudinally extending guide rail along which a cutter-loader is displaceable. Respective conveyor trough sections are carried on the rail sections and each have a trough-section length substantially shorter than the respective rail-section length, so that longitudinal forces are transmitted via the rail sections and not by the conveyor-trough sections. The trough sections form a longitudinally extending trough in which a chain conveyor is effective.

    The invention relates to equipment for the mining industry and concerns guides for a coal plow intended to move the coal plow at the back of a chain scraper conveyor, in particular a single chain conveyor. A known sliding-type coal plow, including a square with an upper guide element, dividing the cavity into two channels C attached to the shelf. The disadvantages of the known coal-plow guide are due to poor hypsometry of the formation and low reliability of operation. The closest in technical essence and the achieved result is a guide for coal plow, including linear sections, consisting of three segments, hinged but connected with each other and with a given vertical-restrictive casing with an average segment and having the plow, with at least the end segments of adjacent linear sections, is connected by means of a common, flexural, hinge rod t2. The disadvantage of this coal plow guide is that during the operation additional loads in the conveyor chain are caused by too much or too little tension, leading to structural damage to the plow equipment. The purpose of the invention is to increase the reliability of operation of the guide and unload the conveyor chain during the process of moving the conveyor. The goal is achieved by the fact that in a guide for a coal plow, including linear sections, each of which is completed. of the three pivotally interconnected segments with channels for the plow chain, attachments from the side to the linear sections of the scraper conveyor, in particular a single-circuit, the end segments of the adjacent linear sections of the guide connected to each other by means of an elastic pivot rod, the length of three the segments of the linear section of the guideline are longer than the length of the linear section of the conveyor to the B-width of the kinematic gap between them. The end surfaces of the end segments of the guide sections outside the contact surface area are made with bevels in the direction of the bottom. In addition, the elastic hinge rod and the bottom of the linear section of the KO fan are located on the same axial line and at the same distance from both channels for the plow drag chain.
