Confidence is growing in a new method of underground gold mining that has the potentiality to reverse the fall in gold output.
A raise uninteresting machine tested out in the stopes has passed with flying colors.
A local drilling contractor used on-site machining equipment to drill 26 m from one sublevel to another at an angle of 26 degrees in what's one of a total of 6 critical projects that, if successful, could take older mines back to being top gold producers.
The large advantage of the proposed new system of mining is it is the gold and only the gold that's extracted at considerably bigger volume.
Corporations are being engaged to think up an ultrahigh-strength backfill that will dispense with the necessity to leave large pillar areas unmined in order to assure safety.
Much new gold is at depth, which ends up in major amounts of the rare metal having to be locked away in shaft pillars and stableness pillars, because blasting snarls up the ground conditions and creates seismicity.
The suggested new technique of mining dispenses with blasting, keeps folk away from the danger areas; facilitates mining round the clock every day of the year and refocuses on money.
Current wasteful mining practise is considered tolerable because it sterilises too much gold in the ground
Greater depth also adds to go time, which means that mineworkers finish up spending fewer hours at the face. Under conventional strategies, miners also need to leave the mine before blasting and only return after the dust has settled.
The new thinking is to mine all of the gold, only the gold, all the time, and avoid leaving 40% of the gold behind in pillars.
The fantastic thing about reef dull is that nobody has to work awfully hard physically and the machine does the work. As there's no need to vacate the mine, productive operation can go on continuously for so long as the shift schedules permit.
