Jan 01, 1988· Mines began re-evaluating backfill as a support system and soon realised that it has many attached benefits to make it a very attractive proposition to them. There are now some twenty mines using backfill in South Africa and various systems have been documented [I-4].
Jun 28, 2020· Mill tailings are the most common sources of backfill in South African gold mines and the backfill material is produced on the surface before being transferred underground. The processes involved in the production of the backfill include preparation, make-up (binder and tailings), mixing of the binder with tailings and distribution.

Coal mining South African coal occurs in layers within sedimentary rocks of the Karoo Supergroup. These are widespread, but coal is restricted to the areas shown in Figure 2. The coal is extracted either by underground mining or by opencast methods. Unlike gold mining, the coal is removed from the site and there is very little surface dumping.
Mining in South Africa: the challenges and the opportunities 2 September 2016 18 • Non-gold mining sector can grow at 3-5% pa, resulting in more balanced country growth rate (double size of non-gold mining by 2028). • If mining had grown at same pace as rest of economy between 1994 and 2013, country's growth rate would have been 4% (not 3.2%)
Abstract: The application of paste as backfill in underground mines has been demonstrated in a variety of mining operations to create advantages in delivering improved production rates and reduced operating costs, providing an opportunity to add value to the business. This can deliver short term gains to an operation as well as enable longer term strategic goals to be enhanced.
Jan 30, 2021· To investigate the physicomechanical properties of stope backfill and to explore the mining conditions for an adjacent pillar, four boreholes, namely, GZK1, GZK2, GZK3, and GZK4, were constructed for taking the backfill core in the test stope. During borehole sampling, it is found that the strength of backfill is usually lower than that of the rock and ordinary concrete, and its resistance to ...
