Problems solved by technology

Among them, porous granular ammonium oil explosive is an industrial explosive with safe, simple and low-cost production process. However, due to the poor mixing uniformity of oxidant and combustible agent in its components, the explosive performance is low and the blasting effect is poor. In view of these shortcomings, People have done a lot of work. Patent CN102659492A discloses an aromatic compound additive. The use of this additive can improve the sensitivity of porous granular ammonium oil explosives and improve the blasting effect, but the increase in explosive sensitivity will inevitably increase the danger in the blasting process. This paper The patent provides an additive for porous granular ammonium oil explosives. The use of this additive will not increase the sensitivity of porous granular ammonium oil explosives, but it can improve the explosive performance of porous granular ammonium oil explosives and improve the blasting effect

Embodiment 1

[0013] Example 1: Taking the preparation of 10 kg of porous granular ammonium fuel explosive additive as an example, the mass percentages of each component of the porous granular ammonium fuel explosive additive are selected as follows: N-N dimethylacetamide 55%, ethylene glycol 45%. Mix and stir N-N dimethylacetamide and ethylene glycol evenly to obtain the porous granular ammonium fuel explosive additive.

[0014] Add the additive into the porous granular ammonium oil explosive (the porous granular ammonium oil explosive is obtained by mixing the composition and mass percentage of 94wt% porous granular ammonium nitrate and 6wt% diesel oil, which can be obtained by referring to the patent CN1227209A) and mix evenly A high-performance porous granular ammonium oil explosive is prepared, and the mass ratio of the additive to the porous granular ammonium oil explosive is 3:97.

Embodiment 2

[0016] Embodiment 2: Taking the preparation of 10 kilograms of porous granular ammonium oil explosive additives as an example, the mass percent of each component of the porous granular ammonium oil explosive additive is selected as: N-N dimethylacetamide 40%, octanol 30%, ethylene glycol 30%.

[0017] Add the additive to the porous granular ammonium oil explosive (the source is the same as in Example 1) and mix evenly to prepare a high-performance porous granular ammonium oil explosive, wherein the mass ratio of the additive to the porous granular ammonium oil explosive is 5:95.

[0018] The measured detonation velocity of the high-performance porous granular ammonium oil explosive is: 3300m / s, and the working capacity: 310ml. Compared with porous granular ammonium oil explosives, the detonation velocity increased by 22%, the working ability increased by 4.7%, and the detonation sensitivity remained unchanged.

Embodiment 3

[0019] Example 3: Taking the preparation of 10 kg of porous granular ammonium fuel explosive additive as an example, the mass percentages of each component of the porous granular ammonium fuel explosive additive are selected as follows: 50% N-N dimethylacetamide, 25% glycerin, and 25% water.

[0020] Add the additive to the porous granular ammonium oil explosive (the source is the same as in Example 1) and mix evenly to prepare a high-performance porous granular ammonium oil explosive, wherein the mass ratio of the additive to the porous granular ammonium oil explosive is 2:98.

[0021] The measured detonation velocity of the high-performance porous granular ammonium oil explosive is: 3200m / s, and the working capacity: 305ml. Compared with porous granular ammonium oil explosives, the detonation velocity increased by 19%, the working ability increased by 3%, and the detonation sensitivity remained unchanged.

Description

technical field [0001] The invention relates to a porous granular ammonium oil explosive additive and its application. Background technique [0002] It is understood that the industrial explosives currently used in mines and engineering blasting are mainly emulsion explosives and porous granular ammonium oil explosives. Among them, porous granular ammonium oil explosive is an industrial explosive with safe, simple and low-cost production process. However, due to the poor mixing uniformity of oxidant and combustible agent in its components, the explosive performance is low and the blasting effect is poor. In view of these shortcomings, People have done a lot of work. Patent CN102659492A discloses an aromatic compound additive. The use of this additive can improve the sensitivity of porous granular ammonium oil explosives and improve the blasting effect, but the increase in explosive sensitivity will inevitably increase the danger in the blasting process.
