Abstract

According to the invention, automatic adjustment of the cutting horizon of a cutter installation or other mining installation is effected with the aid of recognition sensors which detect the footwall rock interface and which are disposed distributed over the length of the cutter or machine guide, wherein the measuring signals from the recognition sensors are acquired by an electronic evaluation and control unit and are utilized in the sense of automatically controlling the adjusting cylinders.
