The shaft development, reaching a depth of 1,123 m, has included 600 m of freezing as the shaft passes through the notorious Blairmore water-bearing formation, with AMC reporting that it designed an innovative headframe approach for the job that has led to the freezing circle being spanned by the permanent headframe, saving time and money since a sinking headframe has not been needed.
development lengths for a given depth are the three to five times longer than for a vertical shaft. Vertical shafts are the preferred method for deposits deeper than 300 m but the development rate is slow and construction costs are very high. Declines or ramps offer early access to shallow deposits, which develops the ore body
LOCATION AND NUMBER OF SHAFTS. Development is conducted for two purposes first, to search for ore and second, to open avenues for its extraction. Although both objects are always more or less in view, the first predominates in the early life of mines, the prospecting stage, and the second in its later life, the producing stage. It is proposed to discuss
