Shape of Mining Shafts Mining Guide
SPEED OF SINKING.--Mines may be divided into two cases,--those being developed only, and those being operated as well as developed. In the former, the entrance into production is usually dependent upon the speed at which the shaft is sunk. Until the mine is earning profits, there is a loss of interest on the capital involved, which,

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 n
