Slope Design and Implementation in Open Pit Mines

Jan 01, 2012· Keywords: slope stability, slope design, engineering geology, fault, open pit mines, SOMAIR uranium mine, OCP phosphate mine 1. Introduction Slopes of mines and quarries, some of which may reach several hundred meters deep, must be regarded as "geotechnical works" in the sense that we speak of mine works or civil engineering works.

Sample Rocks Tests and Slope Stability Analysis of a Mine

The safety and stability of waste dump are vital influencing factors to the mine sustainability and mine employees. Based on a real mine project in a certain open-pit mine waste dump in Tibet, the in situ test on waste rocks from waste dump, including measurements of density, water content, rock size, and natural repose angle, was conducted. Afterwards, these sample waste rocks, of which grain

Evaluation of Open Pit Mine Slope Stability Analysis

The issues concerned with slope stability in the open cast mines have come to forefront in the mining operations due to increasing pit depth. The cut slope stability has the most prominent influence in the productivity and longevity of a mine, collapse of which can lead enormous damages to man and machinery. It is always considered as economic burden to mine production.

Reading: Open-Pit Mining Geology Lumen Learning

Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is
