Mine
Sampling
A committee,
which included representatives from the Mines Branch and the Research Council,
together with the Provincial Analyst, made a careful study of the question of
sampling as applied to bituminous mines. This committee decided upon certain
changes in the procedure of sampling, the principal of which involved the use by
mine inspectors of a portable crusher-sampler in place of coning and quartering
for the reduction of mine samples. This apparatus is made in such a way as to be
readily taken to pieces and packed in the traveling case provided.
These results
are better than could be hoped for, and are a good indication that the
channel samples, as taken, do give a close approximation to the regular output
of the mine.
It is recognized
that carload samples give a better representation of the output of the mines,
and it is hoped ultimately to obtain and test such samples, not only from every
area, but also from each of the principal mines in these areas. It is clear,
however, that such work will take long to complete, and that channel samples
must play an important part meanwhile in evaluating the coal output of the
province.
