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 that are commonly used to extract coal or different ore deposits. It''s not difficult to understand that mining is one of the most dangerous working environments in the world and in this topic, we will go through some of the ...

OPEN PIT MINING THROUGH UNDERGROUND WORKINGS INTRODUCTION A number of open pit mines in Western Australia (WA) are mining orebodies that have previously been mined by underground methods. There are hazards with high risk potential which develop where open pit mines approach and then progressively mine through underground workings.

Slope stability analysis forms an integral part of the opencast mining operations during the life cycle of the project. In Indian mining conditions, slope design guidelines were not yet formulated for different types of mining practices and there is a growing need to develop such guidelines for maintaining safety and productivity. Till date, most of the design methods are purely based on field ...

In open pit mining, it is accepted to trade off some failures for steeper bench face angles, without compromising safety, since it is more economical to deal with regular cleanups . than to have higher stripping ratios. This is generally referred to as a "managed" approach to slope design. A design reliability of 80% is generally accepted in open pit design, which means allowing 20% of ...
