3 coal samples
3.1 coal coal core samples as screening, when drifting test coal, coal coal core samples taken should be consistent with (87) coal to the word No. 656 provides for a number of
Seeking to. thin seam less than 5kg; medium thick seam 5kg ~ 13kg; thick seam less than 13kg.
3.2 from the screening test is less than 0.5mm size fraction product shrinkage take laboratory samples of coal flotation unit, the quality of not less than 1kg.
