SHORT-WALL MINING MACHINE FOR UNDERGROUND COAL MINES

摘要

Short front machine for the underground mining operations with a guide for a drilling apparatus for producing drilled holes for the first anchoring, which is constructed as a scraper chain conveyor with a angle conveyor, whose along the mining face extending leg forms a guide track for a the, which, with a height which are generally equipped with cutting heads is provided, and with a the conveyor in the constructional unit with the advancing in the direction of advance feed device, the by means of hydraulic cylinder is connected to the rear along the mining face extending limb of the angle conveyor and coupled with a clampable between the upper and lower limits, the advance abutment for the return cylinder is provided forming support plungers, characterized in that, on the on the floor of the gallery (8) supported on the floor frame (21) of the support die (22) which, in stretching crosswise to the direction extending guide (36) for at least one displaceable on the drilling device (37) for the production of the first anchoring holes (33) serving in the hanging wall (9) is arranged.
