Underground mines are inherently dangerous environments considering both illness and accidents there are around one million work related deaths around the world every year. The
In this module, I’ll take you through the key aspects related to underground mining activities. In this module, we will look at economic considerations in
Welcome back to the surface mining model. In the previous topic, we learned about different types of surface mining operations, about equipment, about different methods
In the previous topic, we saw that blasting is the mining operation used to break the rock mass in order to facilitate the removal of
The previous topic has established that surface mining operations include several main activities that include the ore extraction or mine of the material, the overburden
In the concept of mining a deposit, mining operations should be planned and organized in order to maximize the productivity. Slope stability issues directly affect
First of all let’s define what we mean with surface mining. Surface mining means the extraction of mineral deposits or coal reserves or stones of
Rock mass failure does not always involves discontinuities. There are cases, especially for excavations, like the tunnel you see on this photo where the stress
In previous topics, we have seen that discontinuities constitutes as a weakness in the rock mass. In fact, failure of a slope, for example, is
In previous topics, we’ve discussed strengths of materials because failure typically occurs when stresses exceed the strengths, it is important to know the stress distribution
