Annotation:  In recent decades, there has been an increase in landslides and an increase in the number of landslide foci, and this process is associated not so much with natural as with anthropogenic factors. According to international statistics, about 80 % of modern landslides are associated with human activities. Anthropogenic landslides, confined to artificial slopes of embankments and excavations, are ubiquitous in all natural areas with favorable lithological and hydrogeological conditions. Anthropogenic landslides were observed at a number of coal deposits in Kyrgyzstan (Kok-Zhangak, Angren, Sulukta, etc.), where loess-like loams, bedrock debris and bedrock were displaced. In the former Kok-Jangak field, several masses of loess-like loams of large volumes were displaced. In this connection, the physicomechanical properties of landslide sites located in Kok-Zhangak were studied. Physical and mechanical properties of soils were studied in field and laboratory conditions on samples of undisturbed and impaired structure, according to GOST. A hydrogeological map of the site is also described. Geological studies allow to accurately determine the depth of bedrock.

Keywords:  soil, loam, natural moisture, specific weight, volumetric weight, porosity.
