摘要： A mining machine (7) is provided which moves from side-to-side in sequential passes across a seam of material to be mined. The machine (7) is carried on rail means (19) and co-ordinate positions of the rail means (19) are measured at locations along the length of the rail means. A trailing part of the rail means (19) is then moved by rail moving means (25) to a new position for a next pass, and the distance of moving is determined from the co-ordinates of the positions previously measured. By knowing the co-ordinates of the positions, the rail means (19) can be moved to assume a desired profile, so that a desired profile of the face of the seam can be achieved on the next pass of the machine (7). Desirably the profile is a straight line. Co-ordinates of the up and down movement of a shearing head (9) can also be measured and stored with the co-ordinates of the positions along the rail means to provide a profile of the seam being cut, and so that on a next pass the intended position of the shearing head (9) can be predicted and moved accordingly. A method of mining embodying the above is also provided.

摘要： 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.

摘要： A mining control system for adjusting the advance of the working tools of a mining machine with respect to working depth and/or working height connects to a detection device that is for recognizing the rock being mined and is carried along by the mining machine. A central command station connects by radio to the detection device of the mining machine. The mining control system comprises a plurality of radio receivers arranged in spaced relationship along the longwall, as well as a comparator, which is used for comparing the intensity of the radio signals received by the individual radio receivers and for retransmitting only the strongest of the radio signals to the central command station for generating the command signals for controlling the advance of the mining tools. It is also possible to transmit the radio signals received by each radio receiver to adjacent radio receivers. A separate comparator is associated to and controls each radio receiver. A radio receiver is allowed to transmit data to the command station only when the signals received by it are stronger than the radio signals received by the other radio receivers.

摘要： A control system for a mining machine which moves in passes across a seam to be mined using absolute coordinates is disclosed. The machine is carried on rail and co-ordinates of the rail are measured along the length of rail. The rail is then moved to a new position for a next pass, and the distance of moving is determined from the co-ordinates previously measured. By knowing the co-ordinates, the rail can be moved to assume a desired profile, so that a desired profile of the seam can be achieved on the next pass. Co-ordinates of the up and down movement of a shearing head can also be measured and stored with the co-ordinates along the rail to provide a profile of the seam being cut, and so that on a next pass the intended position of the shearing head can be predicted and moved accordingly.

摘要： An electro-hydraulic control system for self-advancing mine-roof supports in a high-output longwall mine is used to form a sequence zone behind the mining machine whereby individual supports simultaneously operate in the sequence of prop drawing, advancing and setting so that, during the sequence, the roof in the sequence zone is supported by at least each second support with the length of the sequence phase so depending on the cutting speed of the mining machine that it increases with increasing speed to ensure that the roof exposed by the mining machine is supported without delay.
