Abstract

This thesis addresses the opening, preparation and extraction 24th seam middle bridge in the western part of the 11th floes sites CSA Mine Karvina with a focus on dual-use corridors. It deals with the geological characteristics of the area in question, designing appropriate technologies punching a series of measures contributing to effective stabilization of overburden corridors intended for another use in the exploitation of secondary longwall. In this work I propose technology for longwall mining including safety management system of ventilation in the area. In conclusion, I deal with the evaluation and comparison of my design with commonly used method.
