Stope optimization with vertical convexity constraints
(Springer, 2016)
A new algorithm for the optimal stope design problem is proposed. It is based on a previous methodology developed by Bai et al. (Comput Geosci 52:361-371, 2013a) where a cylindrical coordinate system is used to define ...
The role of gravity flow in the design and planning of large sublevel stopes
(Southern African Inst Mining Metallurgy, 2015)
Sublevel stoping (SLS) is one of the oldest and most used methods for underground mining. It relies heavily on the use of drilling and blasting techniques to remove the rock, and gravity to transport the broken rock to ...
Three-dimensional effect of stresses in open stope mine design
(Taylor and Francis Ltd., 2018)
The stability graph method is widely used for open stope mine design. During the development of the method the effect of induced stresses were included by using two-dimensional or limited three-dimensional stress analysis. ...
A New Criterion for Numerical Modelling of Hangingwall Overbreak in Open Stopes
(Springer, 2020)
Determining stability, quantifying planned dilution, and estimating the potential dilution associated with hangingwall overbreak are critical in the process of stope design in sublevel open stoping mines. To satisfy these ...
Stability assessment of underground mine stopes subjected to stress relaxation
(Taylor & Francis, 2020)
Stress relaxation plays an important role in the design of underground stopes. The aim of this paper is to assess the stope stability in connection with the stress relaxation using a classification approach. Three types ...
Dimensionamento empírico de realce em Sublevel Stoping
(Universidade Federal de Minas GeraisUFMG, 2012-02-29)
Empirical methods should be applied only in situations where the features are similar to those used in their original database. The Stability Graph methodologies proposed by Mathews et al. (1981) and by Potvin (1988) are ...
