'Probably no phase of coal preparation requires the supervision and care that must be given to shooting practices. The type of explosive used is a safety powder known as "Duobel" and has been selected because it is most suitable for the coal mined in the White Oak Mines. Not only must the explosive be of the best quality and best suited for the work of breaking down the coal, but its use must be supervised and restricted. The proper amount to use; the size of the cartridge; the manner of tamping and many other details are looked after so that a maximum of lump and coarse coal is produced after shooting. This view shows the working place after the 'breaker shot' has been fired.'
