Process flow of producing explosive

Abstract

The invention relates to a process flow of producing an explosive. The process flow comprises a site filling station, a filling preparation station and a preparation and distribution system, wherein the preparation and distribution system comprises a preparation working station and a matrix distribution station; materials which are conveyed out by the preparation working station are conveyed to the filling preparation station and the matrix distribution station respectively to meet the requirements for preparing different types of explosives. In order to prepare explosives of different detonation velocities, the site filling station comprises a monitoring unit, a pouring unit and a testing unit; after being input into the site filling station and identified and recorded by the monitoring unit, the materials are conveyed to the pouring unit to be poured into a blast hole together, mixed and sensitized to produce a preset type of explosive; and the explosive is initiated through a detonator and an explosion initiation bomb. A sampling inspection program is also available, i.e., a mixture sample is extracted to detect density and explosion velocity of the explosive, the explosive is continuously poured into the blast hole if the explosive is qualified, and otherwise, the proportion of the components is adjusted and then the materials are input. Due to such design, the requirements for producing various types of explosives can be safely, sufficiently and stably provided within a relatively wide area.

Description

technical field [0001] The invention belongs to a method for producing explosives, in particular to a process flow layout capable of producing both emulsion explosives and multi-detonation velocity explosives, so as to meet the needs of specific conditions in different blasting sites. Background technique [0002] A very common method of controlling detonation velocity is to control the density of explosives during the production process. In the past industrial explosives production technology, a fixed explosives production line can only produce a single type of explosives, such as emulsion explosives, ammonium oil explosives, expanded ammonium nitrate explosives, etc., or mobile ground stations can only produce emulsion explosives. Any one of these production lines has a fixed density value and a fixed explosive detonation velocity, and cannot produce suitable explosives with changes in rock properties. , and when the rock is soft, the selection and production capacity of ...

Problems solved by technology

In the past industrial explosives production technology, a fixed explosives production line can only produce a single type of explosives, such as emulsion explosives, ammonium oil explosives, expanded ammonium nitrate explosives, etc., or mobile ground stations can only produce emulsion explosives

Any one of these production lines has a fixed density value and a fixed explosive detonation velocity, and cannot produce suitable explosives with changes in rock properties. , and when the rock is soft, the selection of explosive varieties is extremely limited, and a suitable method and process is not provided to meet the needs of changes in the blasting environment.

Especially when the ammonium oil explosive is not waterproof, the unit consumption of the emulsion explosive is high, and the rock hardness coefficient changes, it is impossible to effectively replace the explosive type at any time.

Due to the limitations of explosive types, density, and non-adjustable detonation speed, etc., it cannot meet the needs of the blasting site, cannot achieve predictable blasting effects, and increases blasting costs.

At the same time, it affects the safety of blasting, which in turn leads to blasting accidents and secondary disasters, which seriously affects blasting efficiency and production capacity.
