Abstract:

The presented work is structurally divided into two parts. The first part, using finite element methods and potential theory, presents the results of theoretical research on the patterns of stress field formation in the roof of wide-span drawn stopes. The second part proposes a methodology for determining the strength reserve in flat drawn stopes roofs depending on the span size and depth of their placement, as well as recommendations and innovative technical solutions for drawn stopes support and improving their operational reliability under challenging mining conditions. During the construction of special-purpose chambers under complex mining and geological conditions, workings of elliptical, semi-circular, or circular cross-sections are commonly used. The optimal shape of the underground excavation cross-section is selected based on the stability and fracturing of the surrounding rock. In the development of ore deposits, it is necessary to assess the stress state of both extraction and special-purpose chambers under conditions of three-dimensional stress, where the dimensions of the chamber along the x, y, and z axes are approximately equal.
