Description
Summary:The results of experimental and analytical studies into the state of access roadways under selvedges of gently dipping sedimentary sheet-like bodies are presented. The stresses in rock mass under the selvedges of seams are determined. The state criterion was assumed the ratio of the maximal compressive stresses at boundary of a reference circular cross section roadway in an elastic medium and at the boundary of the roadway under the hydrostatic stress field. The results of the instrumental and visual observations in mines as well as the data of equivalent material modeling and analytical solutions agree.
