Větrání při ražení štol a tunelů

Abstract

The diploma thesis deals with the issue of ventilation during stole and tunnels excavation. At present, there is no comprehensive document that would deal with design of ventilation during tunnels and stole excavation. At work I tried to analyze the current state of design of ventilation projects during tunnels and stole excavation on the basis of accumulated data - implemented projects ventilation of tunnels during a excavation. The document summarizes the knowledge of eight ventilation projects that were designed. In addition,there is also a calculation of each individual projects, comparing the values and evaluation for each project separately. At the end of the document there are evaluation results that could help creating a comprehensive document dealing with the design of ventilation during stole and tunnels excavation which are currently missing.
