Phase Planning for Open Pit Coal Mines through Nested Pit

Phase Planning for Open Pit Coal Mines through Nested Pit

Feb 11, 2021 Feb 11, 2021 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
