  • Standard Practice for Manual Sampling of Stationary Coal

    7.7 In extremely cold weather, coal can become frozen on the surface as well as inside the stockpiles. It is preferable not to collect increments manually from frozen coal. Wait until it thaws. If sampling is necessary while coal is frozen, make note of the coal’s condition when it was sampled. It will be
