Abstract - USGS

MINE LIFE. Given a known ore reserve tonnage, the life and daily capacity for a typical mining operation can be determined. Taylor developed an equation commonly used in prefeasibility studies to determine mine life, known as Taylor's rule (equation 3). Based on this rule, the basic equation for C (capacity of ore production in st/d) is:
