Prediction of seepage water pressure for slope stability at the Gol-E-Gohar open pit mine

The paper analyzed major factors that influence the stability of open-pit slope and established the GM (1, N) model based on the program of Xingshan strip mine, which provided an effective method for evaluating the slope stability.

Geotechnical Characteristics

The development of an open-pit mine at Thompson, Manitoba, required the excavation by dredge of 17.6 × 106 m3 of overburden. The overburden consisted primarily of normally consolidated glaciolacustrine soils found beneath Thompson Lake. The paper reviews the geological and geotechnical characteristics of the varved deposits and the basis for establishing the overburden slope configuration. Previous experience on similar dredging projects in Manitoba and northwestern Ontario is reviewed. Performance data collected during the excavation of the dredged slopes are presented. Key words: dredging, slope stability, open-pit mine, glaciolacustrine deposit, varved soil, piezometric response.

Factors Affecting

With the rapid advance of industrialization,the consumption of mineral resources is increasing.For open pit mine,many of them went into deep mining.The current,widespread adoption of open pit slope angle makes deep concave mining has a huge stripping ratio.So many mines in trouble,on the premise of guarantee the deep sunken open pit slope stability increase slope toe can bring huge economic benefits,and a lot of research work has been done.This paper describes the factors affecting the stability of open-pit mine slope,the slope rock mass stress analysis,to calculate the lower steep slope economic benefits,puts forward reasonable suggestions the future research direction of the slope stability of open-pit mine.

Mine Dump

The dumps in the open-pit mining area in the eastern grassland are prone to landslides due to the fragile ecological environment, so it is inevitable to reshape the dump slopes. In order to explore a more scientific method for slope shaping of open-pit mine dump, slope stability analysis were used to compare effect of three types of slope-type (wave-shaped, slope-shaped and step-shaped slope shaping method)in outside dumping site of Baori Hiller open-pit mine. The results show that the slope stability is negatively correlated with the slope angle, and the stability of different shaping slopes is realized as wave-shaped slope (F=2.711)> Slope-shaped slope(F=2.513)>Step-shaped slope(F=1.047), in which the wave type and slope type are all within the safe range, but the step type slope is unstable; in consideration of cost, stability and erosion resistance, it is better to set the slope angle of the dump to 15°.The wave-shaped shaping method of the natural dumping of the excavation field outside the Baori Hiller open-pit mine has the best effect and is worth promoting.
