In South Africa, Grootegeluk Colliery is a typical example of terrace type of mining. Currently, 11 benches are mined, 6 of overburden waste and
The object of collecting coal samples after mining is to determine the quality of coal actually being produced. This coal may differ signiﬁcantly from the in situ seam analysis in that not all of the seam may be included in the mining section, or that more than one seam may be worked and fed to the mine mouth and mixed with coal from other seams.
