Selection of optimal development systems for “Gosha” gold deposit in the Republic of Azerbaijan pdf

Z. J. Afandiyeva, M. B. Osmanov

In 1966, “Gosha” gold mine hosted its first geological exploration works and six ore zones were found. In subsequent years, scientists carried out detailed exploration resulting in 17 known and studied zones. Since 2009, international mining company develops this deposit, and it proved that the areas 13 and 13a are mega-rich with gold ore mineralization.
Implemented investigation of the development system confirmed that Gosha gold mine requires concrete development system that can fully meet natural and technical conditions of the deposit. We studied different development systems for the development of the deposit and gave their outcome in the article. Considering the main criterions and factors necessary for choosing development system, we propose the system “Wells with open face, breaking of ore by blast holes, from the top to bottom”. Strong and weak features, opportunities and dangers of the offered development system and the results of the SWOT analysis one can find in the article. In comparison with others, the proposed variant of the development system has the following properties: it allows saving initial economic losses, and it decreases volume of mining works (filling the developed gaps is not required). Our proposed options for development systems Goshinsky gold deposit fully meet the conditions of natural and technological fields and can be applied to other ore deposits of Azerbaijan and neighboring countries with similar mining and geological conditions.

Keywords: gold deposit; underground development; mining operations; development systems; mineralization; capital expenditures.
