An Approach to Realizing Process Control for Underground …

However, mining engineers have not implemented process control on a mine-wide scale for underground mines. Mineral processing is normally described as being in a continuous state which can be expressed using partial differential equations (PDEs). Mining operations are normally implemented in a serial (e.g. drilling, bolting) …

Digging deeper: Mining methods explained | Anglo American

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds.

Mining Product: Rock Falls

A close companion to Miner Mike Saves The Day, Rock Falls teaches the importance of proper roof scaling in underground mining to avoid injury and improve work conditions. Rock Falls won the Alice Hamilton Award for Excellence in Educational Materials in 2000 and breaks down scaling methods into five easy steps.

What is Rock Scaling & How It Works

1. Removing unstable or possibly lose rocks using hand tools or a rock scaling machine is known as rock scaling.
2. On rappel, deep mining, and tunneling, rock scaling is the safest and most efficient.
3. It's mostly done from the ground down to avoid putting the technicians on top of loose rocks. When it comes to rockfall prevention, this is usually the first phase.
