Mechanized opencast mining is preferred when there is a thick mineral bed of mild inclination, practically continuous and not in pockets, at a low depth and the reserves are plentiful. For coal, a seam of less than 6 m thickness and with less than one million tonnes of quantifiable reserves will not justify the heavy capital expenditure, large amount of interest on it and the depreciation charges.
