The study uses data from completed coal mining projects from selected coalproducing countries. Three formulae are developed and presented for estimating capital costs of underground bord and pillar, surface shovel and truck, and dragline operations. Keywords coal mining.
Coal blending is the process of mixing coals after coal has been mined to achieve quality attributes that are desirable for the coal's intended application ( steam generation, coking). The quality attributes that are most important in blending will differ from one mine site to another and also depend on how the coal seams vary in quality and their final intended use.
A coalmine project was significantly behind schedule, and the company figured it had to hire an additional 1,000 people to catch up.
