OPTIMIZATION OF PRODUCTION PLANNING IN

2014-8-28  In underground mining, development required to reach the orebody is much and increases the production time from the start of the development (Haycocks, 1992). Effective mine planning is required to generate profit (Carlyle et al., 2001). Mine production scheduling is an important problem in mine planning (Gershon, 1983).
