A common practice of sampling thick coal beds (greater than 10 m thick), either by core or by channel, is to divide the bed into intervals no thicker than 1.5 m. In many cases, thick coals are sampled in 0.7 m sections; such sampling provides a detailed stratigraphic section of the bed. Core samples are best for thick-bed sampling.
