Otvírka, příprava a dobývání Ostravské sloje č. 463 Natan na Dole Darkov, lokalita 9. květen

Abstract

In my dissertation I plan opening, preparation and extraction mining ostravské seams No. 463 Natan at Mine Darkov Location May 9. This is the one of the last face at this locality. I make a suggestion of preparing and mining this face unusual way for Mine Darkov. Seam No. 463 Natan has very good coking coal. I plan snicket gate 1,5m high driving with blasting operation and loading with scraper. I plan face equipment with drag-hook plough RHH 800, mechanical supports type DBT 600/1400 and chain conveyer PF3/822. Because of today’s world coal price I plan machines already used at others plants and locality in OKD. I calculate material cost for driving roads at technical-economic evaluation.
