Analysis of the Variation of Friction Coefficient of

Sandstone slopes are common in open pit mining. Sandstones usually contain joints, which when penetrated cause slope movement due to the slope sliding along the joints. The friction coefficient of rock joints is closely related to the stability of the slope [ 1 5 ], though it is difficult to predict as it is associated with several

Application of cusp catastrophe theory to reliability

Jan 01, 2010· As shown in Fig. 3, mining was conducted in the area at three levels, i.e., 280, 300 and 320 m in the north-east of the Xuefeng sandstone open pit, which forms a 60 m slope with several slide surfaces. The stratum direction of the slope was NW 263°/SW 173°, 33 °~40°. The terrain was approximately parallel to the slope.

Abstract LOP

A Brief History of Open Pit Slope Design Slope design is an integral part of the engineering of an open pit, regardless of its size. Most cases the slope angles are a key component dictating the economic viability of a proposed or current mining project. This has resulted in open pit mining operating

Slope Stability Analysis of Waste Dump in Sandstone Open

This paper presents the slope stability analysis for the current as well as projected (final) geometry of waste dump Sandstone Open Pit "Osielec". For the stability analysis six sections were selected. Then, the final geometry of the waste dump was designed and the stability analysis was conducted. On the basis of the analysis results the opportunities to improve the

SLOPE STABILITY ANALYSIS FOR OPEN PITS 1

Analyses of a deep wall in an open pit mine in the Peruvian Andes are used to compare limit equilibrium methods (SLIDE) with distinct element methods (UDEC) when the stability is controlled by rock mass strength. The pit wall has an overall slope angle of 37º and a height of 600 metres with an inter-ramp angle of 45º.
