- Ensuring that coal extraction activities are carried out with good and correct mining rules.- Make sure coal afoided from dilution, bonecoal, contamination, oversizing in Pit and Rom.- Ensure that no coal is left behind when mining is complete.- Carry out continuous sampling of coal in the PIT (JORC Sampling), ROM, Stockpile and Port area (ASTM). which is then analyzed for quality.- Coordinate with contractors if coal is found outside the model.- Taking data on the seam thickness in the pit area on an ongoing basis, to then compare it with the seam thickness in the model.- Make coal plan blending - Make actual crusher to comply with the coal blending plan - Stockpile management- Make a daily report Coal quality maps and coal issues.
