Problems solved by technology

[0003] The currently known ammonium oil explosives mixed trucks have a short delivery distance and a small operating range. Therefore, the vehicles are usually frequently moved at the blasting site of an open-pit mine. For some blasting sites with complicated road conditions, the existing ammonium oil explosives mixed It is difficult to get close to the truck, so the method of bagging on site and manual handling has to be adopted, which seriously affects the operation efficiency and poses a great safety hazard

Abstract

The application relates to an ammonium oil explosive delivery method and an ammonium oil explosive on-site mixing method, belonging to the technical field of explosive mixing. A method for delivering ammonium oil explosives, comprising: feeding compressed gas into a storage container to transport the ammonium oil explosives in the storage container to a delivery channel. The compressed gas is fed intermittently into the delivery channel to divide the ammonium oil explosive in the delivery channel into slugs and transported to predetermined positions along the delivery channel. The pneumatic pulse transmission is used for long-distance transportation, which expands the scope of on-site automatic charging of ammonium oil explosives, and is especially suitable for use under complex on-site conditions. It avoids on-site bagging and manual handling, and improves the automatic operation capability.

Description

technical field [0001] The present application relates to the technical field of explosive mixing, and in particular to an ammonium oil explosive delivery method and an ammonium oil explosive on-site mixing method. Background technique [0002] Ammonium oil explosive is a commonly used industrial explosive. Its preparation principle is to mix granular ammonium nitrate with diesel oil and other additives. There are two production methods of ammonium oil explosives: fixed and on-site mixing: fixed production means mixing, stirring and bagging in a fixed workshop; on-site mixing is to use special equipment such as ammonium oil explosive mixing trucks to mix granular nitric acid Ammonium and diesel additives are transported to the blasting site, and ammonium oil explosives are mixed on-site with on-board equipment, and then directly mechanized into the blast hole without packaging. [0003] The currently known ammonium oil explosives mixed trucks have a short delivery distance ...
