Abstract
The invention relates to a high-performance emulsion explosive mixed and loaded on the spot. Ammonium nitrate and sodium nitrate are thrown into a crusher, are crushed, are sent to a melting pot filled with water according to mixture ratio, are heated to a temperature of between 70 and 80 DEG C and are kept at the temperature to prepare a water phase solution; an emulsifier, diesel oil and engine oil are pumped to a mixing tank and are fully stirred to prepare an oil phase solution; an explosive mixing and loading vehicle is driven to a blasting scene and is hung with a power takeoff device; when the pressure of a hydraulic pump is not less than 10 MPa, the water phase solution and the oil phase solution are automatically pumped to an emulsifier of the explosive mixing and loading vehicle according to proportion of 94:6; after emulsification, a sensitizing agent is added into a mixing device according to mixture ratio and is mixed to form medicine slurry; the medicine slurry is pressed to a hose reel by the pressure of a screw pump; the density and the temperature of the explosive are measured; and after the density and the temperature are qualified, the explosive is loaded to a blast hole for blasting. The high-performance emulsion explosive has high efficiency and a simple formula, reduces a packaging link, has low production cost and low blasting cost, reduces labor intensity of operators and field workers and is safe and reliable.
Description
Technical field
The present invention relates to a kind of emulsion explosive that is applied to big-and-middle-sized surface mine engineering explosion, exactly is a kind of high performance on-site mixed emulsion explosive.
Background technology
At present, the explosive that China produces is mainly based on the packaging final prod explosive, on-site mixed emulsion explosive proportion is very little, the major part of using on-site mixed emulsion explosive is self-produced personal type mine, because the many employings of the prescription of on-site mixed emulsion explosive are moisture up to the water-phase material (ammonium nitrate more than 18%, the mixture of SODIUMNITRATE and water) with the liquid down oil phase material (emulsifying agent of normal temperature, the mixture of diesel oil and machine oil) emulsion explosive that forms of emulsification, this kind explosive viscosity is lower, density refractory is to regulate, brisance is lower, cause this explosive unit consumption in use to be greater than the unit consumption of finished product emulsion explosive, thereby hindered the popularization of on-site mixed emulsion explosive production, and water repelling property difference and shelf lives are shorter.Therefore now be badly in need of a kind of high performance on-site mixed emulsion explosive, satisfy big-and-middle-sized surface mine engineering explosion.
Summary of the invention
The objective of the invention is at existing defective, provide a kind of not only efficient height to people, prescription is simple, has reduced the packing link, and production cost is low, and blasting cost is low and reduced the labour intensity of operating personnel and field worker, and is safe and reliable.
