A HOLISTIC APPROACH TO MINE PLANNING [3] Introduction All mining operations will eventually deplete their economic resources and have to face closure. Some mines may close before fully exploiting their resources, for various reasons, such as labour issues, commodity prices, political instability, insufficient funding, environmental or safety ...

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).

For instance, suppose that a truly optimized mine plan would generate $1,000 million in value. The actual mine plan may generate $800 million in value, and yet be measured to generate $1,500 million in value because the value measurement is incorrect.

The bauxite industry in Malaysia experienced a surge in January 2014, particularly in Kuantan, the state capital of Pahang. Bauxite is the ore that contains aluminum in its natural form, namely alumina (Al 2 O 3) at roughly 50% to 70% [].Bauxite is found 1 or 2 m below the soil surface and commonly mined with the strip mining (opencast mining) method by removing the overlying soil layer [].

Sophisticated methods for long-term mine planning are often used, and the advent of autonomous machines makes the actual operation more predictable. However, the interface between these two timescales, i.e. the scheduling of the mobile production fleet, often limits the ability to operate mines at maximum profitability.
