At what stage did Plant Pool start charging for equipment?? Was it as soon as it left "Area", or arrived at the pit, or on being underground, installed, or when it first entered production??
Reason I ask, all the faces I worked on during development stage in the 1960's used to be undercut, drilled fired and hand loaded onto the face conveyor tail end. It was advanced periodically to keep up with the face development. The face was always supported with wood props until the face broke through to the tailgate road.
Then as the chocks arrived they were installed on the face....I often wondered why they didn't install them as they advanced??
