Abstract
A process for drilling minerals, rock and the like, using rotating disc machines characterized in that materials to be drilled - if necessary rough cut or stress-relieved, preferably frontally in a direction of propulsion, but also radially outwards - are undercut layer by layer, each layer breaking into the open. The process is used in combination with a self-steering propulsion unit which is supported or guided on or by the previously machined/rough-cut working face so that the depth of undercutting remains constant.
