Description of mining methods (step by step)

The mining will be done from the bottom towards the top. A 20-m (66 ft) panel will be entirely mined and mucked before proceeding with the upper panel. The mining will retreat from both sides towards the centre where the access is located. ADVANTAGES OF THE METHOD. The ore recovery is good since no crown pillar is required.

Reverse circulation drilling turned around a gold mine

2021-1-29  Reverse Circulation (RC) drilling is a technique that utilizes a percussive tool (hammer) which is driven by compressed air, supplied via a sealed drill pipe system. As the hammer crushes the rock, the exhausted air then carries the rock chips through the internal pipe up to the rig for collection in sampling bags that record the sampling depth ...
