Pyrotechnic compound for detonation and preparation method and application thereof

Abstract

The invention provides a pyrotechnic compound for detonation and a preparation method and application thereof. The pyrotechnic compound is prepared from, by mass, 30%-70% of potassium perchlorate, 10%-50% of ammonium nitrate, 2%-10% of aluminum powder and 10%-30% of ammonium oxalate and can be ignited under the high-pressure condition. The pyrotechnic compound, an electro-ignition head and a detonating wire are packaged in inner tubes, the inner tubes are put in outer tubes, and a plurality of outer tubes are connected to form a tube set. High-pressure air is introduced into all the outer tubes, current is guided into the detonating wire to ignite the electro-ignition head, then the pyrotechnic compound in the inner tubes can be detonated under the high-pressure condition, and thus the inner tubes and the outer tubes explode to achieve detonation. The pyrotechnic compound for detonation and the inner tubes, the outer tubes, the electro-ignition head and the detonating wire and the likewhich are matched with the pyrotechnic compound in use can be jointly applied to detonation of various mines, stone materials, building stones and the like and can be also applied to dredging of pipelines, looseness after boiler melting and the like.

Description

technical field [0001] The invention relates to a pyrotechnic agent, specifically a pyrotechnic agent for blasting, its preparation method and application. Background technique [0002] At present, in the mine mining technology, explosive blasting and liquid carbon dioxide blasting are commonly used in the process of mining mines by blasting. The explosive blasting method requires very high technical means for operators during the operation process. Due to the instability of explosives Therefore, it is very easy to be dangerous during the operation process. Even if a professional blasting team conducts blasting, there are many unsafe factors, and the safety of operators cannot be effectively guaranteed. In recent years, liquid carbon dioxide blasting has been used. Although this technology avoids the danger of explosives, the construction equipment is huge, and high-pressure liquid carbon dioxide is used for injection. The material requirements for steel pipes are extremely ...

Problems solved by technology

[0002] At present, in the mine mining technology, explosive blasting and liquid carbon dioxide blasting are commonly used in the process of mining mines by blasting. The explosive blasting method requires very high technical means for operators during the operation process. Due to the instability of explosives It is very easy to explode when it is exposed to high temperature, impact and sparks. Therefore, it is very easy to cause danger during operation. Even if a professional blasting team blasts, there are many unsafe factors, and the safety of operators cannot be effectively guaranteed.

In recent years, liquid carbon dioxide blasting has been used. Although this technology avoids the danger of explosives, the construction equipment is huge, and high-pressure liquid carbon dioxide is used for injection. The material requirements for steel pipes are extremely high, the operation is complicated, the cost is high, and pipe explosions are prone to occur. danger
