Abstract
The article describes the studies into the geological conditions and geotechnologies of coal mining in brachysyncline-type fields. It is found that such coalfields have some specifics which governs the choice of the open pit mining technologies to be efficient. The authors propose an approach to justification of a sequence of mining and to selection of geotechnologies for coalfields in brachysynclinal folds.
