Paper presented at the 53rd U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2019
Paper Number: ARMA-2019-1629
... of the FoG characterization were investigated. Firstly, a FoG chart was proposed based on the Mathew's stability graph method with the purpose of predicting the ground class associated with FoG hazard. The stability of excavations was defined on the basis of the potential severity of FoG hazard as minor...

Paper presented at the 53rd U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2019
Paper Number: ARMA-2019-2021
... ABSTRACT: Optimal stope dimensions for underground mining using sublevel stopping method are decided ensuring excavation stability. Stability graph method developed by Mathews, et al. (1980), later modified by different authors is used as an analytical tool to achieve this purpose. Mathews' B...

Paper presented at the 51st U.S. Rock Mechanics/Geomechanics Symposium, June 25–28, 2017
Paper Number: ARMA-2017-0814
... ABSTRACT The stability graph method has been used for more than three decades for the design of stopes in sublevel stoping mining operations. This method estimates the stope size required to reduce operational hazards and achieve continuous production. Over time several improvements have...

Paper presented at the 46th U.S. Rock Mechanics/Geomechanics Symposium, June 24–27, 2012
Paper Number: ARMA-2012-259
... ABSTRACT: Empirical methods in rock mechanics for stope design have evolved since they began to be widely applied in the early 1980s. This paper uses case studies to illustrate the effects of changes in graphical design techniques based on the Stability Graph and Span Graph, as well as changes...

Paper presented at the Golden Rocks 2006, The 41st U.S. Symposium on Rock Mechanics (USRMS), June 17–21, 2006
Paper Number: ARMA-06-1132
.... INTRODUCTION An important question for open stope operators in general, is what is the effect of mining adjacent to previously backfilled stopes? Design methods such as The Stability Graph have been derived from a database of isolated stopes. These are stopes that have solid abutments adjacent to the stope...

Paper presented at the Vail Rocks 1999, The 37th U.S. Symposium on Rock Mechanics (USRMS), June 7–9, 1999
Paper Number: ARMA-99-0013
.... Unacceptable waste dilution plagued many bulk mining operations and traditional trial and error approaches to optimizing stope dimensions became economically unacceptable. Potvin (1988), Potvin and Milne (1992) and Nickson (1992), following earlier work by Mathews et al (1981), developed the Stability Graph...
