ABSTRACT:
The invention relates to a road-milling machine or machine for working deposits, such as deposits of coal, ores, minerals, etc. by surface mining. The machine according to the invention has an arrangement14for detecting the path followed by a milled edge13of a milled strip, with the arrangement for detecting the path followed by the milled edge having means14for measuring the distance between at least one reference point I on the machine and the milled edge. The means14for detecting the path followed by the milled edge co-operate with the arrangement6for steering the track-laying units3A,3B in such a way that the machine follows the path followed by the milled edge. The distance between the at least one reference point on the machine and the milled edge can be set in such a way that milled strips situated alongside one another are exactly aligned relative to one another.
