UNDERGROUND OPERATIONS AT THE DOME MINES
The mine is entered by a central vertical shaft, strongly timbered, and containing two compartments- one for the passenger cage, the other for the large skips bringing the ore to the surface. A man-way, for emergencies, is also provided, parallel to the shaft. The cage is a single-deck steel box, carrying about thirty persons; by means of arrangements above and below, it can also hoist and lower materials needed in the workings.
