Abstract

The invention discloses a special porous granular ammonium nitrate fuel oil explosive for an underground inclined upward blast hole. According to the improved ammonium nitrate fuel oil explosive, a porous granular explosive is bonded and coated, so that the problem of explosive scattering frequently encountered during charging of the underground inclined upward blast hole is solved, the charging success rate is high, the blasting performance is good, the safety performance is high, no toxic gas is generated after blasting, the influence on the human body and the environment is small, and meanwhile, the detonation velocity can reach 3000-3300 m / s. The invention also provides a preparation method of the ammonium nitrate fuel oil explosive. The whole process is safe and efficient, the operation is simple, the method is environment-friendly, the batching time can be completed within one day as soon as possible, the charging time is shortened, the damp risk of the explosive is reduced, and a guarantee is provided for the operation period.

Description

technical field

[0001] The invention belongs to the technical field of industrial explosives, and in particular relates to an ammonium oil explosive specially used for obliquely upward blastholes in downholes and a production process thereof. Background technique

[0002] Ammonium oil explosives have excellent blasting performance and are widely used in open-pit and underground non-coal mining blasting. Underground blasting operations require on-site preparation of explosives, but usually the site environment is relatively poor, staffing is reduced, and operating conditions are limited.

[0003] When conventional powdery and granular ammonium oil explosives are used in upward blastholes, due to the upward / oblique upward angle, the charge will encounter the problem of explosives falling down, the blasting effect is poor, and it is easy to generate static electricity, which is dangerous and mixed. The labor intensity is high and the charging efficiency is low, which affects t...
