Abstract:In the Velenje Lignite Mine, Slovenia, the panel substructures are in sue. Fiber reinforced concrete panels are used because of their advantages which they have in the construction of mine railway lines over other types of substructures. In a development project, a fibre reinforced panel with much better carrying capacity and ductility in comparison with reinforced concrete panels has been developed. The panels, with high-performance fiber reinforced concrete (HP-FRC), which resist greater rock formation pressures have been developed also. These properties are input data for analysis of panel at the outside loading. Because the crack propagation in the length direction as well in the width direction is prevented by the presence of fibres in concrete, energy absorption capacity, toughness and ductility of concrete respectively are increased.
