Image of timber bracing in the stopes. As the ore body is removed the overhanging rock must be supported to prevent a cave in. This is done by means of timber bracings. After ore has been brought to the surface and processed through a concentrating plant to remove the non-metallics, it is fire-refined and cast into ingot form, cake form, or billet form. [Two miners inspect the bracing. Name and location of mine unknown.] Scanned: September 29, 2009 |
