Moolarben Underground required an innovative approach to constructing pre-driven recovery roadway supports prior to advancing their 400-meter-wide longwall into the area.

The heating issue was identified in an inaccessible area of the mine and had experienced several events requiring active management over a long period.

Integra Underground excavated a large dyke from an active longwall block in the Maingate. The dyke was removed using shotfiring, after which formwork was installed and the resulting void was filled with StrataFill®.

As with all longwall mines in NSW, Tahmoor is required to seal their extracted longwall panels.

As part of Ulan Underground’s longwall extraction plan, the mine had the requirement to segregate a series of longwall blocks from the next series.

Mine Projects Australia was engaged by Donaldson Coal (Tasman Mine) to demobilise its three mine entries including installing the final mine seals.

Ashton Underground required a strategy to seal a disused ventilation shaft linking the pikes gully seam to the surface atmosphere. As a permanent seal, the Sealing had to comply with MDG 6001.
