Method of pumping explosive slurry
Patent
·
OSTI ID:6620593
A method and apparatus are described for the manufacture and use of slurried explosives in shut hole and similar operations. Slurried explosives normally consist of at least one oxygen releasing salt selected from the group consisting of inorganic nitrates, and perchlorates and mixtures, a thickening agent, a fuel, and water. Optionally additives, for example agents increasing sensitivity and fuel content, may be added. A method of filling borehole is by pumping an explosive slurry by a primary pump through a hose more than 50 ft in length to a secondary unit in a restricted space. From the secondary unit, the explosive slurry is pumped through a hose inserted in a borehole and an additive is pumped into the explosive slurry. Control devices for controlling the flow of explosive slurry are provided. (4 claims)
