Abstract

775,341. Fluid-pressure blasting devices. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 20, 1954, No. 13859/53. Drawings to Specification. Class 9 (1). Water under pressure is pumped into a sealed, borehole until the neighbouring strata are saturated and a charge of explosive as in Specification 670,453 is then fired, flame-quenching agents being incorporated in the explosive. Specification 743,998 also is referred to.
