Panel Advance Improvements Proposed Benefit

No removal, storage and of vent tubes – increase in cutting

17 hours/100m cycle

No retrieval and reinstallation of reticulation cables – increase in cutting

No retrieval and reinstallation of fan, car and miner cables – increase in cutting

Fan and Box relocation 100m = 30min no LHD required – increase in cutting

Ability to perform powered maintenance during panel advance – increase in cutting
