On the nature of a large anticlinal fold in the Upper Kama salt deposit, its geomechanical and gas-geochemical zonality

Учёные записки Казанского университета: Серия Естественные науки, 2021
Large (more than 10 m in height) folds complicate the longwall mining of potash salts and are accompanied with the formation of foci of gas-dynamic phenomena. In this study, to identify the folding nature, changes in the physical properties of its rocks,
