13. Miners Placing Charges

'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.'

16. Miner Placing a Charge

'White Oak preparation begins when the machine leaves and the miner is ready to shoot down his coal. The shooting inspector on the left has not only located the hole for the miner to drill, but instructed him as to what angle he must bore his hole to contain the necessary explosive used in dislodging the coal from the seam. The "kerf" made by cutting machine is plainly visible in this picture and you will note the cutting or "bug dust" have been removed before the coal is shot. The length of the auger used by the miner and the width of the bit which determines the size of the hole bored, is also carefully regulated.'
