Abstract
A kind of detonator allowed for use in coal mines, it is characterized in that in the detonator device, having added the fluorochemical flame-cooling agent, both having solved is the easy moisture absorption of detonator allowed for use in coal mines powder charge of flame-cooling agent with Repone K, free-running property is poor after the moisture absorption, is difficult for powder charge, Can is had problems such as corrosive nature, also solved is that the red lead is relatively more responsive and poisonous in the detonator allowed for use in coal mines of flame-cooling agent with the red lead, cause and produce dangerously, workman's health problem such as predispose to damage has also played strong restraining effect to the ignition of biogas simultaneously.
Description
The invention belongs to mine blasting equipment, especially belong to a kind of detonator allowed for use in coal mines that uses flame-cooling agent.
Existing detonator allowed for use in coal mines is made up of fire element, priming explosive, charging explosive in detonator and shell, and adding Repone K is done flame-cooling agent in charging explosive in detonator.The content of Repone K in charging explosive in detonator is many will to reduce the capsular detonating capability, and the content of Repone K has lacked will reduce capsular flame arrest ability.Because Repone K has water absorbability, makes the free-running property variation of the charging explosive in detonator that contains Repone K, is difficult for powder charge, simultaneously metal casing is also had corrosive nature.Particularly in the bigger area of overcast and rainy humidity, produce, store difficulty, capsular detonation ability reduces, and effectively the warranty period also shortens, thereby directly influences the safety of makers' production and colliery blasting.
On March 23rd, 1 disclosed Chinese patent CN86104575A patent to have disclosed a kind of be the mining short electric detonator of flame-cooling agent with the red lead, though this detonator has solved the Repone K moisture absorption and has corroded problems such as primer casing, but make the medicament comparison sensitivity that becomes owing to add the red lead, dangerous during production, the red lead also has cumulative toxicity simultaneously, the workman has grown duration of contact, can severe damaging body health.
The present invention is that the above-mentioned deficiency of capsular of flame-cooling agent is a purpose to overcome with Repone K and red lead just, adopts a kind of novel flame-cooling agent, makes the capsular technical qualification can satisfy security needs in makers' production and the colliery blasting better.
Detonator allowed for use in coal mines of the present invention, it comprises: shell, fire element, priming explosive and charging explosive in detonator.It is characterized in that: charging explosive in detonator of the present invention is made up of high explosive, fluorochemical flame-cooling agent and the tackiness agent that adds.Because the present invention has added an amount of fluorochemical flame-cooling agent in charging explosive in detonator, make detonator when igniting, the fluorochemical steam that produces can be coated on around the Sauerstoffatom of explosion centre, both reduced the temperature of explosion centre, reduced the ignition chance of gas and coal dust again, strong restraining effect has been played in the ignition of gas and coal dust.Simultaneously because the passivity of fluorochemical and non-hygroscopic has been avoided the corrosion to primer casing; Fluorochemical is insensitiveness very again, makes detonator production safer.
Detonator of the present invention, the fluorochemical flame-cooling agent in its charging explosive in detonator comprises: the fluorochemical of basic metal, alkaline-earth metal and ammonium, and sodium aluminum fluoride, wherein the effect with Sodium Fluoride, Calcium Fluoride (Fluorspan), aluminum fluoride and sodium aluminum fluoride is best.These flame-cooling agents both can use separately, also can mix use.Both can partly add in the powder charge at detonator, and also can add in the whole powder charges of detonator, in the ordinary course of things, the add-on of fluorochemical flame-cooling agent should account for 0.5～20% of charging explosive in detonator gross weight, is preferably 1～6%.
Detonator of the present invention, its charging explosive in detonator can adopt one or more the mixture in the existing various high explosive, but are best with the effect of hexogen.
In order to increase the free-running property of high explosive, make its easy filling, the electrostatic effect when reducing charging explosive in detonator, charging explosive in detonator of the present invention can also use the tackiness agent granulation, and used tackiness agent comprises: inorganic salts tackiness agents such as silicate, phosphoric acid salt, borate; Natural glues such as gelatin, shellac, peach gum; Composite adhesiveses such as polyvinyl alcohol, Vinyl Acetate Copolymer and Resins, epoxy.Be best with silicate, shellac, peach gum and polyvinyl alcohol wherein, in the ordinary course of things, the usage quantity of tackiness agent should be 0.1～5% of charging explosive in detonator gross weight, is preferably 0.5%～2%.
Detonator of the present invention can adopt one or more the mixture in the existing various priming explosive.If do not use priming explosive, also can make nonpriming material detonator.
Detonator of the present invention, its shell can be by metallic substance such as copper, steel, multiple copper steel, copper plated steel; Non-metallic material such as pottery, paper, fiber board, plastics, synthetic resins are made, and are best with copper steel, multiple copper steel, copper plated steel wherein.
Detonator of the present invention, its tube shell bottom both can be flat, can be again and felt resentful, but be best with the effect of feeling resentful.
The present invention both can be used as the allowed for use in coal mines short delay detonator, also can be used as the allowed for use in coal mines delay detonator; If the employing electric igniting assembly then can be used as electrical detonator,, then can be used as on-electric detonator if adopt non-electric igniting assembly.
Advantage of the present invention is simple except that structure, detonation property stable, mainly be to adopt the fluorochemical flame-cooling agent to replace flame-cooling agent of the prior art, both guaranteed the capsular gas safety, Repone K moisture absorption corrosion shell, the uneasy congruent difficult problem of the responsive production in red lead have been solved again, simultaneously also can increase economic benefit for manufacturer, produce 4000 ten thousand capsular production lines per year for one, compare, can increase economic benefit 20～400,000 yuan every year of the present invention with existing detonator allowed for use in coal mines.
Following Example, just in order to further specify the present invention, rather than the limit of the present invention.
