A wet afternoon (despite it being high summer), so herewith some doodles. I trust they will be of interest. These are examples of the sorts of machinery and structures associated with underground (reef/hard-rock) gold mining on New Zealand’s Coromandel peninsula during the late Nineteenth and early Twentieth Centuries.

Also known as ‘Headframes’, these structures are placed at the surface (top) of vertical shafts, and, through the use of cables and cages (the equivalent of elevator cars) raise and lower men and materials to various places within the mine.
The various biuldings associated with the mine are visible in the background, with the most important being the Winding Engine House immediately behind the ‘head which contains a steam-powered winch. This uses cables, led over large-diameter wheels placed on the top of the ‘head and attached to the roofs of the cages to haul these the cages up and down in response to set bell-signals from the miners travelling within them.
