Ražení překopu 11 002 ve ztížených hornicko-geologických podmínkách na Dole Karviná, závod ČSA

Abstract

As my thesis I chose a project of the 11002 cross drift tunnelling in the mine Karviná, ČSA plant from the level of the 22nd bed and 11th block to the level of the 31st bed and 14th block. In the introductory part I described generally the bed geology. Further I projected a concept of tunnelling by blasting operation a modern machines for drilling and loading as well as separate ventilation by blowing. I gave a detailed account of the method of locking of incohesive rock in the mining workings surrounding and the method of prevention of coal and oxygen substance contact in the passing and tectonic deformation. The next topics I focused on in my thesis were conditions for use of safety explosive, safety measures in regard to blasting operation and responsibility definition. My thesis is concluded by a technical interpretation of projected method and applied technology.
