Roadway re-utilisation is possible in longwall face.

In longwall mining, the layout and organization of the working face determine the possibility of roadway re-utilisation.

Double unit longwall face allows for the re-use of roadways (gate roads) since two faces are developed adjacent to each other and can share the same set of main roadways.

This layout leads to better efficiency and cost-effectiveness by reducing the need to develop new roadways for each face.

Single unit and Z unit longwall systems typically do not allow for this reuse because each face generally requires separate infrastructure.

Therefore, roadway re-utilisation is possible in Double unit longwall face.
