Introduction. There are more than thousand lode mineral deposits of gold, rare metals, polymetals, and uranium in Eastern Siberia. Only 10% of them are in operation. Geotechnical conditions of the fields are poorly studied, therefore geotechnological parameters are not explored at a sensibly reliable level. The authors have conducted multi-year research of geotechnical processes at goldfields of Eastern Siberia.
Methodology. During geotechnical processes investigation at goldfields the authors have created the methods and techniques calculating the parameters of stable pillars and chamber exposures, selecting rock pressure control procedures based on the complex analysis of mining and geological factors: physical and mechanical properties of rock and ore, tectonic faulting, cryologic state of rock in a massif, high natural gravitational and tectonic stresses of rock mass, technogenic stresses in structural elements of underground geotechnologies.
Results. For practical use of research results, methodological and normative documents have been developed for a range of mines, including Darasun, Kholbinsky, Irokindinsky, Novo-Shirokinsky, Maiskoe, Konevinsky, Mnogovershinnoye, Birkachan, Kedrovskoe, etc. The documents have undergone expert exanimation of industrial safety and have been approved by RF Rostekhnadzor for practical use at gold mines.

Key words: gold lodes; geotechnics; rock pressure control; pillars; chamber roof and walls exposures; physical and mechanical properties of rocks; natural and technogenic stresses.
