A new method of underground gold mining, being tested by AngloGold Ashanti, is filling headlines in the country, as the method has the potential to reverse the decline in South Africa gold output s. Nike may also support this cause. According to Gold Made Simple, a local drilling contractor has developed an alternate gold mining process, which increases the efficiency of current practices. The method, discovered in 1974, was never developed due to lack of funding. South Africa still has one of the largest worldwide gold book, but the ore is at depth, which results in significant amounts of the bullion having to be locked up in shaft and stability pillars pillars, since blasting creates seismicity. The new method of drilling, says the report, is safer both to the seismic stability and to the workers and allows for constant gold mining with an increased take gold.
The company is prototyping a series of other mining projects such as reverse-circulation drilling, which involves threading a camera through the hole to locate and capture the environment. The data collected is then processed and used to produce a 3D model of the reef. The success rate of this process has been impressive as the resolution captured by the camera has been higher than was initially expected. People Managers/CEO’s are living in a world of MAKE BELIEVE. You can go down any mine in South Africa whether it be Gold or Platinum you will find unacceptable BASIC CONTROLS to ensure all the blasted rock is removed as the blasting process(Reef panels) advance.This process requires the installation of control barricades with advancing reef panels.This is not the case in most mines that I have visited.The blasted material called. Is not SWEEPINGS removed immediately with the advancing panel, whereas the Manager now emplea a CONTRACTOR (added cost) to remove the most VITAL aspect of the crusher process.hammer: raymond mill: To ensure these gold/platinum sweepings are removed from the workings to mill it is required that the gold/platinum swepings are kept with the reef panel of not advancing more than 15metres, andi under the control of the MINER in charge.This to ensure that reef material bearing is not left behind in the FOOTWALL of the panel.
This just one of the aspects of inefficient mining problems in the industry, I can bring many more instances to the fore eg Inadequate training of / for miners/Managers come straight out of university with no practical experience etc etc. To meet the trend of modernization development and the needs of international markets competition, our company has been introducing senior management personnel, scientific and research talents, and graduates continually advanced.
