Vliv vysokého kotvení na stabilitu dlouhého důlního díla

Abstract

The dissertation deals with the problems of the influence of the high anchoring system on the stability of the long mine work. This dissertation contains two vital points which deal with research part of the high anchoring system and the very influence of the high anchoring system on the stability of the mine work. The first part of the dissertation aims to familiarize with the materials, technologies and applications. The second part of the dissertation looks into the collaboration among the high anchoring system, short rod bolts, curved reinforcement and the system of filling the space between the curved reinforcement and the rock mass, also known as the Bullflex system. To solve this task, mathematical models in Plaxis 8.2 2D software were used. This software is based on the numerical method of the finite elements, also known as the finite element method (FEM). The aim is to prove the influence of the long cable anchors (the high anchoring system) on the stability of the mine work and its interaction with the other elements of the reinforcement system.
