There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]

This paper presents a phase planning method specially designed for coal deposits with nearly horizontal, bedded coal seams. The geology of this type of deposit is modeled into a column model, instead of a block model, to avoid coalrock mixing in blocks. A nested pit generation algorithm is developed for producing a series of nested, leaststrip ratio pits with a column model as its input.
