Abstract
A waterproof granular explosive composition which like conventional ANFO explosive, is excellent in handleability, for example, being usable in bulk form and having fluidity and can be produced by an easy process, and which exhibits satisfactory water resistance in an immersion time envisioned in practical use and further exhibits explosion performance. In particular, an explosive composition comprising porous prill ammonium nitrate and a nitro compound optionally together with an antiblocking agent characterized in that a waterproof resin coating film is formed from a thermosetting resin and the above components are covered with the waterproof resin coating film.
Description
Technical field
The present invention relates to be widely used in the blasting explosives composition of industrial blasting operations such as rubble, mining, coal mining, tunnel driving.More specifically say, relate to the water resisting property grain powder composition that can directly fill in boring etc. and use.
Technical background
The explosive that is used for industrial blasting operation, that knows has nitroglycerine explosive, water-bearing explosive, ammonium nitrate dynamite, a fried medicine of ammonium nitrate (to call the ANFO explosive in the following text) etc.In these explosives, the ANFO explosive is the better simply explosive of manufacture method, with other explosive for industrial relatively, as cheap, safe explosive and known.And the ANFO explosive is made up of the particulate matter of tool flowability, can directly pour in the boring, or load with packing machines such as precompressors.Owing to these reasons, the ANFO explosive uses very extensive.
The main component of ANFO explosive is a porous matter granulous ammonium nitrate, and majority accounts for more than the 90 weight % of explosive integral body, and the ANFO explosive is that liquid fuel compositions such as light oil are blended in explosive in this ammonium nitrate.On the other hand, ammonium nitrate dissolves 120g approximately in 0 ℃, and dissolves 950g approximately at 100 ℃ in 100g water, it is characterized in that being very easy to be dissolved in water.
Therefore ANFO explosive, when explosion has water to exist in boring, or underground water is when immersing, or has water to immerse situation in the boring in the rainy day, and ammonium nitrate often dissolves in holing easily, isolates light oil, thereby loses explosivity.Therefore, packing explosives such as the nitroglycerine explosive that under such condition, has a water resisting property, water-bearing explosive with regard to use, or use filling (packing) in advance in the ANFO explosive of the water-repellancy wrapping material of plastic cartridge casep and so on.Yet under the last situation, the explosive of use is than the high explosive of ANFO explosive price, and blasting cost rises.Then under the situation, not only lost originally the advantage of filling in bulk simply, and between the hole wall of packaged explosive and boring, produced the gap, the situation of ANFO dynamite charge in boring compared, can not obtain sufficient blasting effect with direct.And such be packaged in ANFO explosive in the plastics tubing can be in being filled to boring the time by the sharp keen stone equivalent damage of drill hole wall, the result makes water immerse package interior, so ANFO explosive moisture absorption sometimes and lose blast performance.Exist under the situation of a large amount of water in this external boring,, water must be discharged for preventing the explosive come-up.
As the trial that solves above-mentioned all problems, several use method of filling explosive of the plastics tubing of not packing into have been proposed.For example develop and a kind ofly in the ANFO explosive, add the explosive of water-retaining agent and make its practicability (Japan special permission open communique 2000-16891 number), but water absorbing properties is insufficient, when using explosive, must anhydrate from interior the removing of holing with lift pump earlier, increase the operation of charging.And in open communique 2001-31490 number of Japan special permission, 2001-48689 number, 2001-89285 number and 2002-47088 number, attempt in all sorts of ways and improve the water resisting property of ammonium nitrate, but they all must have fusion, the control of heating, cooling temperature and time when forming overlay film of high melting-point wax, and the spraying of coating, coat with the manufacturing of emulsus explosive, the complicated operations and the special devices such as precoating operation of powdery ammonium nitrate, expection manufacturing process is complicated and need long-time.
Summary of the invention
The present inventor develops a kind of operability advantages such as can in bulkly the using of ANFO explosive, good fluidity of utilizing as far as possible, and has water that can existence in not removing boring and the water resisting property of using during submerged water, and the grain powder that can easily make with simple device, carried out deep research, the result has finished the present invention.
Promptly the present invention relates to
1, a kind of blasting explosives composition is characterized by and contains ammonium nitrate, nitro-compound and thermosetting resin.
