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.
