GEOMECHANICAL ASSESSMENT OF ROADWAY MAINTENANCE DURING UNDERWORKINGS
DOI: 10.25558/VOSTNII.2018.02.005
The article presents the issues of underworking of current development headings by working faces of underlying seams. Investigations in full-scale conditions have established the nature of rock deformations in different zones. The methods for calculating rock convergence along the boundary of the mine opening are presented. The support type was chosen and the measures for the way of saving the undermine workings is considered.
