Keywords: Rock excavation, Safety analysis, Slope stability, Surface mining Introduction The geotechnical study and slope design was conducted of an open pit copper mine (500 m long, 200 m wide) situated in Rajasthan, India. The ore body is 40 m wide and 313 m long. The ultimate pit depth is 148 m. The ore body is striking NNW-SSE
16-2-2014· r/mining is the site from which this comes. It is new to me. And probably won’t be visited often by me. It consists mainly of questions like the following—to which question no answers are posted: I am a mining engineer based in the American Southwest. I’ve been looking at comparing cash costs of production for differing mining companies.
