Návrh dobývání porubu 145436 v oblasti s geologickými problémy

Abstract

The purpose of this thesis is to design a mining longwall no. 145436 so the most ef-ficient method of mining can be achieve. There were identified geological problems during excavation preparatory therefore we can expect unfavorable conditions for mining. Despite initial breakthrough excavation and sizing of mining technology, mining works were not started. In relation to above I will propose in my thesis two alternatives longwall mining 145 436. The proposed mining methods I will compare in economic terms. The most important aspect for choosing the right method of extraction is to take into consideration more favor-able economic indicator. But before I suggest anything will acquainted you with the locali-ty, in which the longwall mined will be done. This is a mining plant number 3 and I will describe its history and specific technical-mining issues. I will describe also tamping pre-paratory workings. Based on that I will propose variants of longwall mining and in eco-nomic evaluation will offer the best option.
