Have a group of employees that need basic training in terms of mine planning software? Or perhaps a refresher course to get those rusty skills oiled up? Or perhaps professional development is the next step for your employees... Be it as it may, the School of Rock prides itself as a preferred service provider in terms of empowering your group of individuals to tailor-made requirements.

This method of carrying the back in an overhand stope is shown at position G in the figure below. It is claimed that it makes drilling more convenient if machine drills mounted on a bar are used - 911 Metallurgist.
I tend to get confused when it comes to expressing ramp gradients in a ratio format vs percentage format. Below is a quick and easy reminder that you can use. The ramp gradient is exactly the same for both examples.
A very warm congratulations to Jaco, Tim, Lukona and Lizanne from Sishen and Kolomela mines for completing the Mine Planning Basics Short course, presented at the university of Pretoria this week. These guys sweated it out by creating a mine design as well as a LoM schedule using mine planning software generously provided by RPMGlobal and Optron. Also congrats to the prize winners - Jaco & Lizanne! I wish you guys all the best with your careers!!
Are you 100% confident that your Excel calculations are correct in determining fleet numbers? Are your roads accurately set-up in terms of stop signs, single carriage areas, steep gradients, single-bay dumps? What happens when you have congestion in your pit, how does Excel cater for that? With the HAULSIM simulations you can set up your site accurately to generate realistic results in terms of fleet numbers. The simulations allow you to run a host of possible scenarios, to e
Doing a pit optimisation for a client, I realised you can utilise 2 different beneficiation plants by cleverly setting up the expressions. The material above the higher cut-off grade (COG) gets "dispatched" first and committed to that plant. That material is then taken care of. The remaining material above the lower COG is then "dispatched" to the other plant, leaving the remaining material as waste. If you work on the cash flow basis, Whittle will fill the plant that generat
know the feeling... when you're losing precious time because of fighting the software instead of running iterations and scenarios... You will never have confidence in your schedule if you do not have 2 or 3 scenarios to test the flex of your system. Your superiors want a number of options, not just one answer. RPMGlobal's XPAC SOLUTIONS products allows you to do just that - run scenarios instead of suffering in silence. With almost a decade of open pit scheduling experience
Ilmenite is a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. Apollo astronauts found abundant ilmenite in lunar rocks and the lunar regolith. Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO3. Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys. Most of the ilmenite mined worldwide is used to manufacture titanium dioxide, TiO2, an important pig
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 tha
Side stoping is an extreme of combination stoping in which the working face of the stope is vertical. The face is parallel to the raises just as the face in flat-back stoping is parallel to the levels. Breast stoping refers to the working of a flat orebody, or a flat section of an orebody, just as coal is mined from a flat coal seam. That is, a slice is worked in a horizontal direction. The assumption is that there is no open stope either above or below the slice, or else the
