From the result of comparison of seam 100, 200, and 300 channel sampling and stockpile
sampling can be obtained increase in parameter of TM equal to 2,48%, IM equal to 0,5%
and Ash equal to 3,29% in stockpile sampling, this is because coal in stockpile is not
treated properly or not controlled optimally. Further TS parameters of 0.2% decreased
