Bulk emulsion matrix loading equipment for open-pit mines

Abstract

The invention relates to bulk emulsion matrix loading equipment for open-pit mines, which comprises an emulsion matrix storing and conveying device, a sensitizing solution storing and conveying device, a washing water storing and conveying device, an injector for injecting emulsion matrix and sensitizing solution into blast holes, an explosive conveying pipe and a mixer, and the bulk emulsion matrix loading equipment further comprises a pneumatic loading device and an equipment frame. With the adoption of the optimized design and the structure of the bulk emulsion matrix loading equipment, the bulk emulsion matrix loading equipment for the open-pit mines has the advantages of wide application range, small equipment size, simple power source, safe and reliable production process and the like.

Description

technical field [0001] The invention relates to a bulk emulsified matrix filling device for an open-pit mine. Background technique [0002] 85% of the finished explosives in our country are made of paper or plastic packaging bags. Explosives are packaged in waxed paper tubes or plastic tubes, plastic bags, pads, cartons, packing tapes or fiber bags lined with plastic bags. Tons of explosives The packaging cost is about 600 yuan / ton. Existing bulk explosives used include porous granular ammonium oil explosives vehicles and emulsion explosives vehicles. Emulsion explosives vehicles are divided into two types: on-board milking or ground station milking. Ground station milking is a large-scale on-site mixed truck, both of which are hydraulic The power system, with a tonnage of 8-15 tons, is very expensive. In 2010, the market share was 15%, of which the share of bulk emulsion explosive vehicles was only 5.8%. Most open-air blasting projects use packaged explosives with No. 8 i...

AI Technical Summary

Problems solved by technology

[0004] At present, packaged explosives are used in domestic open-pit mines. The density of the charge process cannot be adjusted, coupling charge cannot be realized, water accumulation in the hole cannot be effectively removed, and the cost of perforation increases, resulting in an increase in blasting costs.

The use of the current large-scale bulk explosive system is limited to individual large-scale open-pit mines, which is very limited. At present, open-pit mines do not have small and medium-sized open-pit mine bulk emulsion matrix filling equipment.
