Common mining methods in S.A. Panning • Panning for gold is a manual technique that is used to sort gold from other sediments. Wide, shallow pans are filled with sand and gravel (often from river beds) that may contain gold. Water is added and the pans are shaken so that the gold is sorted from the rock and other materials,To combat the build-up in rock stress, areas are mined through a series of smaller excavations. These help move the high stress zone away from the large excavations and create a lower stress zone above and below the smaller excavations. A destress cut is mined horizontally through the orebody on a grid pattern supported by pillars.
