Abstract
A longwall control system controls a longwall support and facilitates the remote inspection of the longwall support. The longwall support comprises a plurality of hydraulically operated supports. The longwall control system comprises a plurality of shield control devices respectively associated with the supports for rearranging the supports in the sense of robbing, advancing, and setting. The longwall control system further comprises detection devices for detecting inspection values associated with the operating parameters of the shield control devices. The longwall control system also comprises a hand-operated device. The hand-operated devices comprises signaling devices, such as a readout or display. Long-distance transmission devices transmit the detected inspection values from the detection devices to the hand-operated device, and the signaling devices provide signals representative of the transmitted inspection values.
