Quantification of the intact geological strength index for rock masses in hypogene environment
Andrea Russo, Iván Vela and Esteban Hormazabal
Friday, December 11, 2020, 03:56 PM - 04:06 PM GMT-3

The Geological Strength Index (GSI) was introduced as an empirical tool to scale the intact rock properties, from samples to a jointed rock mass scale. Since his first conception, GSI was estimated in an empirical way, according to the proposed chart and according to a visual estimation of degree of fracturing and joint condition. Along the years, GSI has been modified for a better rock mass characterization, as for example including a massive rock mass category or presenting a special chart to

Friday, December 11, 2020, 06:50 PM - 07:20 PM GMT-3

Alluvial mining for diamonds started in India and for centuries alluvial mining was the primary source of diamonds. Hard rock mining of primary kimberlite on an industrial scale had only emerged with diamond discoveries in South Africa in the 19th century. Initially, kimberlite pipes were mined as open cast mines, and only within the second half of the 20th century that underground mining was implemented.

A Simplified Geotechnical Risk-Based Approach for Extraction Level Pillar Design in Block/Panel Caving Mines

Definition of the extraction-level layout, including geometry and dimensions of the excavations is an essential aspect of the design of any block/panel caving operation. The design needs to guarantee that the excavations remain stable and perform as intended during the life of mine, i.e., prior, during and after caving production takes place, a span of time that frequently involves decades. The layout of these excavations involves an intricate network of drifts, access tunnels, drawbells and oth
