The average vertical height of over-burden above the tunnel the pockets was 150 feet, and actual

over-burden measured above the blast was 72,000 cubic yards. It was expected that the blast would not only remove the whole of the over-burden but would in addition break back beyond its vortical height an amount of about 15 to 20 per cent.. and that the total amount of rock brought down by the shot would be approximately 200,000 tona.

The amount of explosive used therefore amounts to about 0.28 of a lb. to a cuble yard of over- burden, this quantity being fixed in the light of experience gained In the ordinary routine quarrying operations,

had previously. been carried out to measure the force exerted by the wave of con- cussion through rock by setting up steel rods, half an inch in diameter, at various distances from a blast of known charge and noting which of the rods fell over and which remained upright. By calculating the force required to overturn a rod, and noting its distances from the centre of the blast, it was possible to plot zones of pressure. This was done in order to get an idea as to whether he effect of the blast would reach- the dam. about 1,000 feet away and whether it would be htenso unough to open up u'fissure below its foundations or do .other | damage.
