Analytical Studies Concerning the Shape of Metallic Frame Flexible Support
Determination of rational values of curvature radii of roof beam and stands to solve the problem of selecting rational shape of metallic frame flexible support under various mining and geological conditions of coal mines. The necessity to solve the problem of the determination of rational shape of metallic flexible support has been substantiated. Methodology to solve the problem of improving metallic frame support with the help of analytic equations of structural mechanics is represented. Shapes of mine working cross-sections as well as metallic support depending upon coefficient of lateral spreading obtained as the calculation results have been obtained. Further tendencies in research to improve mine working support have been determined.
