Abstract

The issues connected with the reinforcement of mine guns is a topic very often discussed nowadays. In the Ostrava-Karviná district, the bolted reinforcement started to be used with the reinforcement. However, the experience with bolted reinforcement was not great. The benefits of bolts or high anchoring itself came eventually, even in the complex conditions of the Ostrava-Karviná district. The main part of this thesis is to be acquainted with bolted reinforcement and high anchoring itself. I also focus on the explanation of the principle of the joint influence over high anchoring and arched reinforcement. In the last chapter, there is a simplified draft and calculation of high anchoring with arched reinforcement for the parameters of the local coal mines.
