The coal delivered from the mine that reports to the coal preparation plant is called runofmine, or ROM, coal. This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground ...

WhatsApp: +86 18203695377This 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.
