Abstract
A longwall support control for controlling the movements of the longwall support units and the advance heading in the longwall of a mine comprises a plurality of control units, of which a separate mining shield control device is locally and operationally associated to each longwall support unit. Each mining shield control device comprises a multi-channel radio transceiver, such that the mining shield control device is in a simultaneous transmit and receive mode with a decentralized operating device for receiving control signals and for transmitting inspection data. The mining shield control devices may be interconnected and each mining shield control device may include an amplifier.

A longwall support control for controlling the movements of the longwall support units and the advance heading in the longwall of a mine, comprising:
- a central control system, and
- a plurality of control units, of which a separate mining shield control devices is locally and operationally associated to each longwall support unit, the mining shield control devices being connected via radio to a decentralized operating device for inputting control commands and for feeding back inspection data,
- wherein each mining shield control device comprises a multi-channel radio transceiver, such that the mining shield control device is in a simultaneous transmit and receive mode with the decentralized operating device for receiving control signals and for transmitting inspection data, and wherein the mining shield control device is programmed in such a manner that control signals that are received via radio, can be converted into functions of the longwall support unit when the control signal stores a code word that is associated with the called up mining shield control device.
