Abstract

Movable shoring device for the automatic extraction and removal of coal in long front exploitation, in which the extraction machine, carried out for example as a coal scraper, is driven in a guide rail, arranged parallel to the coal front, preferably in contact with this, which also leads, completely or partially, the traction means for the extraction machine, and in which are provided, distributed over the length of the shoring, displacement cylinders for the advancement of the shoring equipment, characterized in that the guide rail is a hollow or self-supporting rail known per se, provided with guide channels for the traction chains, and that in said rail they attack, preferably in an articulated and direct manner, the cylinders of the traction devices. Displacement, which have, at their ends on the side of the embankment, stops for the fastening of a wall of ar rake, which is constituted by side plates, fastening plates or the like, being inserted, between the guide rail and this tow wall, devices for driving a scraper chain belt or other conveyor belt.
