MINE PLANNING BASICS FRIDAY - BOARD & PILLAR COAL MINING!!

The board & pillar mining method consists of driving a series of narrow roads, separated by blocks of solid coal, parallel to one another, and connecting them by another set of narrow parallel road ways driven nearly at right angles to the first set. The coal pillars formed are extracted after the development of the mine leasehold and this later stage of extracting coal from pillars is known as depillaring - Mining Funda.

ARE YOUR MINE DESIGNS SAFE??

How sure are you that your mine designs have the minimum number of switchbacks? Have you tested the impact of having one switchback less, how that reduces your strip ratio and down-the-line costs, not to mention the health & safety of your employees ...? What about your benches & stacks, do they honour the geotechnical slope angles to prevent slope failure...? Your ramp systems on your interim high-walls - do they tie up with your final design and serve as dual access for that rainy day when you need it most...? Difficult questions I know, but prevention is better than cure as they say. Using state-of-the-art mine design software and almost a decade of design experience, I can help you sleep

IS YOUR PIT OPTIMISATION ADJUSTED FOR THE CURRENT ECONOMY??

The mining industry is notorious for its volatile nature as commodity prices fluctuate. History shows that it's the companies that can adjust to the market changes the quickest that lead the pack. Mining on a 5-year old mine design that was based on a Whittle shell all those years ago can mean you're either leaving value in the ground, or more detrimental, you're now mining in areas where profitability is going South... With almost a decade of Whittle open pit optimisation experience I can help you dust off that old Whittle model, and make sure your mine is set up to run at maximum profitability under current economic conditions... Doesn't hurt to make sure now does it...

BLAST FROM THE PAST THURSDAY - UNDERGROUND BLASTING!!

MINING ROCKSTAR OF THE WEEK - DOLOMITE!!

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone. Dolomite is rarely found in modern sedimentary environments, but dolostones are very common in the rock record. They can be geographically extensive and hundreds to thousands of feet thick. Most rocks that are rich in dolomite were originally deposited as calcium carbonate muds that were postdepositionally altered by magnesium-rich pore water to form dolomite. Dolomite is also a c
