摘要： A passive detonation cut-off device for a solid line of explosives operates by directionally controlling the detonation pressure of an accidental detonation wave of an explosives line and by using this directionally controlled detonation pressure to sever the explosives line to prevent further propogation of the detonation wave. The device comprises a body having two through holes extending through the body and at least one blast hole connecting the through holes and extending from one of the through holes to the outside of the body.

摘要： A booster for detonating cap-insensitive explosives is provided comprising a container having a main body portion and a neck portion of smaller cross-sectional area than the main body portion and having an opening in the neck portion for introduction of a detonating-fuse-insensitive explosive charge which fills the main body portion, and a detonating-fusesensitive explosive charge which fills the neck portion. The booster of the present invention is conveniently prepared and handled or loaded and has inherent water-resistance even though not necessarily water-proof and though inexpensive water-soluble explosive ingredients may be employed.

摘要： The invention is a container especially suitable for packaged blasting charge. A particular embodiment is one of the type used in mines for support on a stick or a pole, at points where a local blast is required as for removal of hang-ups of ore, protruding rock formations, and the like. The container is a bag or envelope of internally valved type, made of preformed flat or folded flexible sheet material, preferably a tough elastic heat sealable polymeric film or sheeting material suitably inturned and sealed to form a self-closing compartment for liquid or flowable slurry explosive. A supplemental pocket may be formed at the side of the main compartment for supporting the charge on a stick or pole. The main compartment is sealed along both sides and across one end and is closed by a flat lying valve element integral with one of the main side walls but sealed to the other main side wall across part only of its width and along a line spaced from the end of the valve element. A filler opening is thus provided at one or both sides of this cross-seal.

摘要： The present invention relates to improved blasting agents. More particularly, the invention relates to a water-in-oil emulsion blasting agent containing sodium nitrate (SN) in an amount of from about 40% to about 70% by weight of the total composition. The water-in-oil emulsion blasting agents of this invention have a water-immiscible liquid organic fuel as a continuous phase; an emulsified aqueous inorganic oxidizer salt solution as a discontinuous phase; particulate inorganic oxidizer salt; an emulsifier; and optionally a density reducing agent. Preferably the blasting agents contain from about 10% to about 40% ammonium nitrate (AN) in addition to SN.

摘要： Slurry blasting compositions of low water content and high density, including substantial proportions of calcium nitrate as an oxidizer component, can be sensitized in various ways to produce economical explosive compositions. Sensitizers may include aluminum powder, granular explosives such as smokeless powder, TNT, etc.; a particularly preferred sensitizer or fuel is ethylene glycol. Solid carbonaceous fuels and conventional thickeners may be added. The calcium nitrate may be produced directly from burned lime with nitric acid and/or other nitrates.
