Development of combined blasting/water infusion technique for coal breaking
Technique involves insertion of explosives charge into borehole, and then volume of low pressure water is pumped into surrounding coal mass by means of infusion tube; while water pressure is still being applied, charge is fired, superimposing high pressure impulse in water, which is transmitted into numerous cleavage planes and breaks in coal. (See also - discussion p 105-9; Colliery Guardian v 188 n 4857 Apr 1 1954 p 383-90, v 189 n 4876 Aug 12 p 215-8)
