For narrow reef hard rock mining to break out of these constraints and to really make progress in the 21st century, it is necessary to follow the lead of the soft rock mining industry and change the technology of mining. In the underground coalmining industry, coal cutting has been proven to be the most cost-effective solution

Variations in ultra-deep, narrow reef stoping

2021-4-14  for narrow reef mining in ultra-deep operations in very hot rock. The stope ventilation and cooling needs are driven primarily by the difference between the air temperature and that of the rock front being excavated. These needs depend on the face utilization, geometry, face advance (rate and direction), layout, backfill, use of water and

AUTOROCK RIGS FOR ROCKBOLTING IN NARROW REEF

2009-10-15  Between 2000 and 2006, platinum production from the South African mines expanded from 206 to 307 tonnes (DME, 2007). Most of this additional metal has come from traditional “narrow” reef stoping, generally taken to mean stoping in working places with a mining height of less than 1,5 metres. It is well known that narrow-reef stoping presents
