Abstract
Based on the analysis of the 2017-2021 recordings from the Kharino seismic station (the Altai-Sayan seismic stations network) and the 2002-2019 satellite imagery, the trigger of the July 18, 2020 earth-slide at Elbashinsky waste rock dump of the Kolyvan Anthracite Deposit (Novosibirsk region) has been established. The study of natural oscillations of the mine waste dump allowed estimating its stability and thus contributing to environmental and industrial safety in surface mining of solid minerals.
