Analysis and Generalization of Experience in the Application of Technologies for Supporting Mine Workings in Difficult Mining and Geological Conditions

An analysis of the technologies for securing mine workings in difficult mining and geological conditions has been conducted. The options for fastening with the use of self-fastening roof bolting in combination with reinforced cages and metal meshes are considered; sprayed concrete, applied according to the technologies of “dry” and “wet” sprayed concrete; fiberglass and basalt-plastic roof bolting; plugging of rocks in difficult hydrogeological conditions.
