Abstract

In my thesis i suggest opener, preparation and quarrying ostravas mining seam justin no.436 on mining sites n.1 of Darkov.this is about one of six planned future coalface from former mine of 9.Kveten, which passed under mining site n.1. thishappened from combination of mines Darkov and Karvina on the date of 1. january of 2015. Because of that i will use new name.at this time i cant say how many of this coalfaces will be conquered, but i will focus on seam of Justin .Seam of Justin no.436 containshigh quality coking coal, hopefully there will be coal mining of these high quality seams,when they were incurred considerable costs for excavation of tunnels and thereby making them avalible . I will suggest technology for preparation and quarrying. I will try suggest already used methods for excavation and quarrying in coalfaces of ostrava, which should bring most economical reset. and use of already used machinery . Like a last thing i will make technical and economical appreciation and count cost for mining. I suggest meke breakthrough high 3 metres with universal loading machine NSU 1E. And coalface should be equiped with the mining harvester SL300 and mechanical reinforcement FAZOS - 15/33 - 2x4020 and scraper conveyor type R850.
