Definitions

  • a self-advancing mine roof support for supporting a mine roof in the vicinity of the path of movement of a mineral (eg. coal) cutting machine along the mineral face, said support having means for advancing it and a control means for said advancing means, said control means including a device, responsive to the passage of a wal cutting machine, arranged so that the advancing means will not operate to advance the support until the cutting machine has passed the support and acted directly or indirectly on said device.
  • a device responsive to the passage of a wal cutting machine
  • FIGURES 6 and 7 are semi-diagrammatic views showing a suitable form of lamp arrangement for use with the system shown in FIGURE 1.
  • the electrical equipment on each chock cornprises a high current (eg. cadmium sulphide) photoelectric cell 10, a memory relay having a relay coil 11a and contacts 11b, a ⁇ sequence relay in the form of a pressure switch 12 and a solenoid-operated hydraulic valve 13.
  • a hold-on relay 10a is connected in parallel with the photo-electric cell.
  • a diode may be connected across the relay coil 11a for intrinsic safety.
  • the over-current device at the control panel is set so that if more than a predetermined number of memories or solenoids are energised yat once, it gives an alarm signal.
  • the potentiometer 34 may be calibrated in terms of the number of memories or, when used in the solenoid lines, the number of the solenoids which must be operated lline also takes care of (b) and (e) as either of these conditions will cause the operation of several memories, in the case of (b) by stopping the sequence altogether and in the case of (e) by lagging so far behind the cutter that several memories are energised.
