1926

The second of these conditions constitutes a difficulty in the Pench Valley due to the fact that in most cases the roof and floor of the seam are composed of black shale very &m:lar in appearance to much of the coal. [...] The coal here is very hard and it would have taken practically a whole day to cut one sample by means of the chisel so the rest of the sample was cut by miners using the ordinary miner's pick under the supervision of the writer. [...] The average value for the seam as a whole is given by averaging the results in the proportion of two of floor coal to one of roof coal this being very closely the ratio between the thickness of each part. [...] Owing to the thickness of the seam six feet of the roof coal are taken out in first mining and the floor coal is dressed out in the rear so that none of the dip workings give a full section of the seam and owing to the changing thickness it was not considered advisable to attempt to take a composite sample. [...] The more easterly one was being unwatered and the seam was exposed just above the water level in the face of the incline It was therefore impossible to obtain a sample here but with a view to seeing whether this was an easterly extension of the coking coal which had previously been found to exist to the west of Rolla a basketful of coal was cut from the exposed corner of the seam and treate
