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.
Claims80
An apparatus for adjusting a cutting horizon of a mining machine of the type which is guided along a machine guide positioned at a mining face having a footwall rock interface, the apparatus comprising;
- a machine guide;
- an electronic evaluation and control unit;
- a plurality of recognition sensors to detect the footwall rock interface, said sensors being connected via transmission lines to said electronic evaluation and control unit to transmit measuring signals thereto;
- a plurality of hydraulic adjusting cylinders having moveable pistons, said cylinders being connected to said electronic evaluation and control unit to receive an output therefrom and associated with said machine guide to adjust said machine guide relative to said mining face;
- wherein said plurality of recognition sensors are disposed distributed along said machine guide, said electronic evaluation and control unit processes said measuring signals to produce said output, and said plurality of hydraulic adjusting cylinders use said output to adjust said machine guide and, thereby, the cutting horizon of the mining machine.
