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 its input.
The Felmlee Coal Co. opened a shaft mine near the Findlay mine about four years ago and ship some coal from their mine. When C. A. White inspected this region in 1868 he found that the McHugh mine at Independent had been running a long time and that there were other mines in the same locality which were supplying a local trade.
