GOLD MINING

2. DRILLING HOLES FOR EXPLOSIVES DSCF3031 (2)

Compressed-Air Drill

In underground goldmines, the gold was contained within quartz rock , known as ‘reefs’.  The reefs had to be broken-up and to do this required the use of explosives, placed into holes drilled into the quartz rock.  Compressed-air was used to drive the machines used to drill these holes.   The image above shows two men using a rock drill (based-on the Edgar’ patent) with light being provided by candles  placed in holders (known as ‘spiders) inserted into the walls of the working. This image  is a study in shadows.

Note: Drawn with a pigment liner with an 0.3 mm nib, on cartridge paper.  Image measures 3.5 in x 4 in. (76 mm x 114 mm).
