  • Shaft construction QueensMineDesignWiki

    TypesDesignCollarDevelopmentDevelopment RatesShafts can be either vertical or inclined. Inclined shafts decrease the crosscut lengths from orebody and are typically used in developing countries and where the ore body dips at less than 60 degrees. Vertical shafts have the advantage of experiencing greater hoistingspeeds, lower maintenance costs, and for the purposes of pre-production are sunk more quickly in almost any ground types. In the past they have been the most commonly considered and appear in most new mines.
