Phase Planning for Open Pit Coal Mines through Nested

2021-2-11  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 coal-rock mixing in blocks. A nested pit generation algorithm is developed for producing a series of nested, least-strip ratio pits with a column model as its input.

The factors to be considered in the design of transfer station are as follows: When a city or entity faces hauling waste “longer” distances, a transfer station may be a viable option. Transfer station costs should be less than the cost of hauling to the landfill directly with collection vehicles (direct haul).
