An Overview of Slope Failure in Mining Operations

Abstract: The primary aim of every twenty-first century mining operation is to extract as much ore as possible in a safe and economical manner. Failure in mine excavation occurs when the shear stress acting on the rock is greater than the shear strength of the rock mass. The stability of rock slopes in open-pit mine and quarry operations is extremely important from both economic and safety points of view because unstable slopes can result in the loss of human life and damage to properties. This paper presents an overvie… Show more

“…Bednarczyk (2017) has stated that open pit mines in Poland have a slope safety factor between 0.75 to 1.65 and 1.12 to 1.60 for dump areas. Another study in America shows that the slope of an open pit mine tends to be stable when the safety factor is greater than 1.2 (Kolapo et al, 2022).…”

“…For the sustainable development of lignite mining, whenever unexpected sliding phenomena occur their causes must be identified, and appropriate measures must be taken in order to eliminate their effects [1,2,[11][12][13][14][15][16]. Monitoring stability conditions and the development of early warning systems are the main ways to prevent slope failure that may result in material and/or human loses [1,[17][18][19][20][21][22][23][24].…”

“…Rock slopes generally exhibit discontinuity planes such as joins and faults (ISRM 1978). Low strength geological structures with unfavorable spatial orientation are critical for slope stability (Kolapo et al 2022). In addition to the presence and condition of the discontinuities on the rock mass, information regarding the presence of water in the subsurface has major importance to evaluate its influence on the occurrence of ruptures (Menezes et al 2019).…”
