【 摘 要 】

The Republic of Sakha (Yakutia) belongs to the most important mineral resource and mining industrial region of Russia and occupies a leading place in the extraction of diamonds, gold, tin, antimony, and also has huge reserves of peat. An analysis of the state of violations during mining operations was performed. The thermomechanical state of health of the active layer has been studied. It is established that the complete freezing of the seasonal layer occurs in October-November, which is taken into account when developing new, earth-saving mining technologies. As a result of the carried out researches and new technologies of mining, providing simultaneous internal dumping, which reduces the areas of disturbed lands. Key words: deposits of the permafrost zone, placer deposits, peat, disturbance of the earth, active layer, earth-saving technologies of mining operations.
