Sudden Rock Failures In Mining Coal Seams Of The Kizel Basin

An analysis is performed for the conditions of mining the Kizel Coal Basin at depths greater than 600 m. It is shown that sudden failures of strong rocks occur in the mine-working floor sections, where the underlying layers possess low deformation properties.
