Stop Mining Method
Stop Mining Flat Deposit In the previous topic you were introduced to the different methods adapted to mine underground deposits. Well the basic elements are common to most underground mining operations, there are many variations in the theme. In the next three topics we will see how these methods can be adapted to mining deposits […]
Mining Engineering & Mineral Exploration Economics
Mining Engineering is a lot about applying the knowledge of applied science and Engineering Mechanics to the successful extraction of useful geological resources. So in this first module we will overview the mining process in its entirety and identify those aspects which are the realm of the mining engineering. Then in the next three modules […]
Rock Mass & Rock Matrix – Discontinuities
In this topic we will discuss what constitutes a rock mass and its relevance for engineering.in this photo, you can see a rock face and what is quite clear is that the rock is not homogeneous. Compare to this specimen of sandstone, which has a uniform color and no clear planes crossing it. In contrast, […]
Mining Geomechanics – Stress & Strain
We’re going to introduce in this topic the two key variables required to define the fundamental behaviour of materials. These variables are stress and strain. In many engineering applications it is required to assess how a structure deforms or behaves under a load. Making such an assessment requires some knowledge about the material constituting the […]
Mining Exploration Process
How Explorers develop an exploration strategy, how they develop an exploration model and design an exploration program and select the optimal exploration tools to carry out that program. As usual of the talk will end with a series of learning points from this talk. There are two fundamental truths about the exploration industry; the […]
Effect of Pulp Density on Gold Flotation Recovery
There are a host of other factors that could be discussed relative to their impact on the effectiveness of free gold flotation. One of the most consistent trends experienced over the years in gold flotation has been the need for carrying out flotations on ground ore pulps having relatively high percent solids loadings by weight. […]
Cave Mining
In the previous topic, we considered methods of stope mining were the stopes were intended to stay open and collapse and collapse of the roof was not an intended outcome. In some situations however, it may be permissible or even desirable that the roof of the mine collapse to fill the stope as mining proceeds. […]

Witwatersrand Gold Deposits
Here is some history of the Witwatersrand Gold Style Ore Deposits as they related to South Africa since the arrival of the Dutch and the southernmost tip of the continent in 1652. The Dutch set up a small fort where Cape Town stands today and started Market Gardens as a place that the Dutch East […]
Uranium Geology
I’ll start with a general discussion of uranium its uses, production, resources and the main uranium ore minerals. Then I want to focus the bulk of the course on the types of Uranium Ore deposits, discussing as I go along how those deposit types are formed and how we go about exploring for them. Then […]
