• Description:
  The field test has confirmed the validity of the new alternative gate road system under actual mining conditions. Field observations indicated that the alternative gate road design significantly improved tailgate roadway stability under existing ground conditions. Field measurements support the results of the model analyses that suggested that reversing the gate road pillar arrangement would shift the higher abutment loads toward the gob of the previous panel and away from the tailgate of the current panel, thus reducing ground pressures and improving tailgate ground conditions.
