“…Pore-water pressure from SEEP/W is exported to SLOPE/W analysis inputs. The main geotechnical parameters are taken from the study of Khomyakov et al (2013) for the Almaty region: friction angle, cohesion, and unit weight of clayey loam [10].…”

Landslides bring destruction to buildings, and nearby located structures and mostly occur in rural areas. Such hazard commonly takes place in mountainous areas in Central Asia. Kazakhstan region has highly vulnerable areas to rainfall-induced landslides in South-Eastern parts due to presence of many mountains. The purpose of the research is to demonstrate the effect of slope geometry on slope stabilityunder heavy rainfall in Almaty, Kazakhstan. Transient seepage analyses were conducted using Seep/W while limit equilibrium slope stability analyses were performed using Slope/W. 15 sets of numerical analyses were carried out on different slope angle and slope height incorporating the soil-water characteristic curve and unsaturated permeability and unsaturated shear strength of soil from Almaty. According to the obtained simulation results in GeoStudio software for seepage analysis, the pore-water pressure is increased almost for 80 kPa at the mid slope of each simulation. The change of FoS for the gentlest slope with 27 degrees slope angle is the lowest for 10 m slope height and the highest for 30 m slope height, whereas the change of FoS for slope with 45 degrees of slope angle (9%) is almost the same for all slope height.

“…The water saturation of cover soils, such as loam, sandy loam, clay, and loess, can occur as a result of rainfall saturation (infiltration), rising subsoil water level (filtration), as well as anthropogenic impacts [20,21]. Studies related to determining the stability of landslide-hazardous slopes often use the physical and mechanical properties of soils in the mainly dry state due to the lack of data on the elastic properties of watersaturated soil.…”

This article presents a comprehensive examination of the physical and mechanical properties of cover soils characteristic of the landslide slopes of Ak Kain, Kok Tobe, and Shym Bulak of the Trans-Ili Alatau, which are located in close proximity to the borders and in the city of Almaty itself. By analyzing previous known landslides in the region, and of a similar type in some countries, the authors identify three main reasons for the occurrence of a landslide on these mountain slopes. These include the water saturation of slope cover soils absorbed during spring rainfall, as well as technogenic and gravitational reasons. The authors conclude that landslides are often caused by soil water saturation. Therefore, it is proposed to consider slope soils as a two-phase medium. The algorithm for determining the physical and mechanical properties of two-phase soil is generalized, and specific calculations are performed based on the considered methods and algorithms. The results obtained for some types of loose soils, such as sandy loam, loam and clay varieties, are given in a systematic form in the tables, which are necessary for an extensive study of the mechanisms of occurrence of landslide processes in water-saturated soils of these slopes through stress-strain state determination.

“…Specified were the regularities of formation and criteria of predicting of gold-ore sites of unconventional gold-sulphide vein-embedded type, represented by the industrial Suzdal deposit and promising small deposits and ore occurrences (Zhaima, Mirazh, Baibura and others) [16][17][18][19][20]. According to their genesis, these deposits are referred to the hydrothermalmetasomatic type, formed in the Hercynian cycle under collisional geodynamic environment (С2-3-С3), localized in the Zaisan sutural zone and of a significant material value [4,8].…”

The region under consideration is part of the Central Asian mobile belt system, organized by a large geo structure of the Greater Altai (GA), which integrates geological structures of the Rudny Altai, Kalba, Zharma-Saur and adjacent districts of Russia and China. The regional goldore sites vary by ore formation types, age, geological formation conditions and mineralization scale. The largest among them are the Ridder-Sokolny gold-polymetallic deposit in the Rudny Altai and the Bakyrchik deposit of the gold-sulphide-carbonaceous type in West Kalba, comparable in many ways with the world sites of Sukhoi Log and MurynTau in the black shale strata. In recent years, much attention was paid to prediction and assessment of the unconventional (apocarbonate) goldsulphide type of mineralization, associated with the island volcanic-carbonate-terrigenous formation С1v2-3 (the Suzdal deposit and others). The present paper considers new results acquired from the studies of the gold-ore sites of the Suzdal type.
