Problems solved by technology

[0002] At present, due to the large amount of explosives used in the occasions where blasting is required, in most cases, the finished explosives are transported to the blasting site for blasting, but the finished explosives are dangerous explosives, and there are safety problems in all aspects of production, transportation and use
[0003]In addition, the permitted emulsion explosives in coal mines are in the form of packaged powder rolls, which require manual charging, so the labor intensity is high and the charging efficiency is low, especially for upward blast holes. Loading is more difficult
In addition, the charge of the finished drug roll is uncoupled charge, and the blasting effect is poor.

Embodiment Construction

[0035] The finished emulsion explosive is formed by sensitization and foaming of the latex matrix under the action of a sensitizer. Therefore, the production of the emulsion explosive must first prepare the latex matrix.

[0036] The latex matrix of emulsion explosives contains a water phase material and an oil phase material. The water phase material may contain a mixture of ammonium nitrate, sodium nitrate and water, and the oil phase material may contain emulsifiers, mineral oil and complex waxes. Mineral oil may contain one or more of diesel oil, engine oil, and the like. Compound wax can be a mixture of ozokerite and paraffin. It should be understood that the water and oil phase materials are not limited to the listed materials.

[0037] In addition, the latex matrix also contains a certain amount of additives as foam accelerators. Generally speaking, the additives are acidic substances, such as citric acid.

[0038] Commonly used emulsifiers are SPan-80 or polyisobuty...

Abstract

The invention discloses a method for preparing a coal mine-allowed emulsion explosive. The method comprises the following steps of: preparing an emulsion matrix on a ground station and conveying the prepared emulsion matrix with charge equipment to a blasting operation site; and mixing the emulsion matrix and a sensitizing agent and then filling into a blast hole to sensitize the emulsion matrix in the blast hole to obtain the emulsion explosive. According to the method of the invention, the process of preparing the emulsion explosive by sensitization and foaming in the blast hole is a complete coupling charging process, so that the blasting effect is good. As manual charging is replaced by mechanical charging, the charging efficiency is high. In addition, as the emulsion matrix is fully sensitized to form the emulsion explosive after the emulsion matrix and the sensitizing agent are filled into the blast hole, high safety is guaranteed in the conveying process.

Description

technical field [0001] The invention relates to the technical field of explosive manufacture, in particular to a preparation method of emulsion explosive for blasting. Background technique [0002] At present, due to the large amount of explosives used in the occasions where blasting is required, in most cases, the finished explosives are transported to the blasting site for blasting. However, the finished explosives are explosive dangerous goods, and there are safety problems in various links of production, transportation and use. [0003] In addition, the emulsion explosives allowed in coal mines are in the form of packaged powder rolls, which require manual charging, so the labor intensity is high and the charging efficiency is low, especially the upward charging of the blast hole is more difficult. In addition, the charge of the finished medicine roll is a non-coupling charge, and the blasting effect is poor. Contents of the invention [0004] In order to solve one or...
