The paper discusses operations aimed at creating a safer natural or man made rock slope by artificially inducing the displacement of unstable elements by blasting. A detailed analysis of the problems with the use of explosives present when conducting these activities is carried out focusing on the advantages and disadvantages of this technology. The results of two examples of demolition of inst...

The determination of the acceptable slope angle for open pits is a key aspect of the mineral business, as it implies seeking the optimum balance between the additional economic benefits gained from having steeper slopes, and the additional risks resulting from the consequent reduced stability of the pit slopes. The difficulty in determining the acceptable slope angle is related to geological un...

9 Rock mass characterization requires a deep geometric understanding of the 10 discontinuity sets affecting rock exposures. Recent advances in Light Detection and 11 Ranging (LiDAR) instrumentation currently allow quick and accurate 3D data 12 acquisition, yielding on the development of new methodologies for the automatic 13 characterization of rock mass discontinuities. This paper presents a m...

In this study, the Lagrange element strength reduction method is used to explore slope stability and as an evaluation of underground mining end-slope coal in a rock-stability analysis. A numerical analysis model established herein using geological conditions for coordinated open pit with area Anjialing Open-Pit Mine Underground No. 2 Mine. Additionally, evolution law open-pit studied proposed s...
