Abstract
The invention discloses a rock powdery emulsive oily explosive and a production method thereof. The explosive comprises rock powdery emulsive explosive, porous granular ammonium nitrate and light machine oil based on the proportions (1: 0.16: 0.064). The production method comprises the steps of: exactly weighing the porous granular ammonium nitrate and the light machine oil according to proportion requirement; evenly mixing in a mixer; further exactly weighing the rock powdery emulsive explosive according to the proportion requirement; and putting the explosive with the mixture into a two-dimensional mixer; mixing for 5 minutes at the rotation speed of 25 rotations every minute. The product is accordant with the national industrial standard, can meet the requirement of the explosive filling quality of an explosive filling vehicle to emplacement holes with any position, realizes the mechanical explosive filling work, has even explosive filling intensity, has high production efficiency, and can guarantee the exploding quality.
Description
Technical field:
The present invention relates to a kind of explosive and manufacture method thereof, relate to rock powdery emulsive oily explosive and manufacture method thereof particularly.
Background technology:
In the long-hole blasting project technology of ore deposit, ground, use pneumatic loading device or explosive loading truck to replace the manual explosive of loading, can enhance productivity, but require comparatively strict the viscosity and the free-running property physical behavior of explosive, viscosity is excessive, be unsuitable for pneumatic loading device powder charge in the big gun hole, viscosity is too little or do not have viscosity, and windstream can come out explosive blowback in the big gun hole, cause dust from flying, pollute working face, it is healthy to have a strong impact on the workpeople, and has increased the blasting operation cost.The rock powdery emulsion explosive ratio that existing Chinese patent ZL03131865.7 provides is more suitable for explosive loading truck filling big gun hole, but when explosive loading truck upward during the insufflation of powder drug of hole, emplacement, explosive still takes place to be returned medicine in the hole and returns the dirt phenomenon of being scattered outside the hole, environmental pollution has limited the abundant use of explosive loading truck to a great extent.
Summary of the invention
The objective of the invention is to: easy prescription of a kind of rock powdery emulsive oily explosive and production method are provided, be equipped with ammonium nitrate and lightweight machine oil with rock powdery emulsion explosive, ratio is 1: 0.16: 0.64, form with two-dimensional mixing machine uniform mixing, the every performance index of its product all meet " People's Republic of China's weapons industry standard " of 2004-04-29 issue, and can satisfy explosive loading truck and no matter all not return medicine to the hole powder charge of any direction emplacement, return dirt, change manual powder charge, realize mechanical charging, charge density is even, the production efficiency height, blasting quality is secure.
The technical solution that realizes the object of the invention is an easy prescription and production method.A kind of rock powdery emulsive oily explosive is characterized in that: this explosive is made up of rock powdery emulsion explosive, porous grain dress ammonium nitrate, lightweight machine oil, and symplasm amount ratio is 1: 0.16: 0.064.
The manufacture method of above-mentioned rock powdery emulsive oily explosive, it is characterized in that uniform mixing forms in the two-dimensional mixing machine for the rock powdery emulsion explosive of (1: 0.16: 0.064), porous grain ammonium nitrate, lightweight machine oil add with mass ratio, its step is earlier ammonium nitrate and lightweight machine oil to be mixed with mixing machine in proportion, rock powdery emulsion explosive was mixed 5 minutes in proportion 25 rev/mins of rotating speeds with said mixture with the two-dimensional mixing machine again.Product of the present invention is compared with existing rock powdery emulsion explosive, and identical point is " People's Republic of China's weapons industry standard " that every performance index of two products all meet the 2004-04-29 issue; Dissimilarity is: rock powdery emulsion explosive is an oyster white, viscosity presents hand and grabs not agglomerating, free-running property is good, easily play dust during filling hole, emplacement, invention product rock powdery emulsive oily explosive is slightly yellow, and its viscosity presents hand and grabs agglomeratingly, and free-running property shows as hand and grabs agglomerating, unclamp promptly and loose, do not have dust during filling hole, emplacement.
Below in conjunction with embodiment the present invention is further described.
Embodiment
Embodiment 1: require accurately to take by weighing ammonium nitrate in proportion and mix standby in mixing machine for 6.4 kilograms with lightweight machine oil for 16 kilograms, other gets 100 kilograms of rock powdery emulsion explosives and aforementioned mixture places the two-dimensional mixing machine, change mixing 5 minutes with per minute rotating speed 25, promptly get rock powdery emulsive oily explosive, the sampling inspection test meets national sector standard.
Embodiment 2: require accurately to take by weighing 32 kilograms of ammonium nitrates in proportion, 12.8 kilograms in lightweight machine oil, two things are put into mixing machine to mix, accurately taking by weighing rock powdery emulsion explosive places the two-dimensional mixing machine for 200 kilograms in addition, again aforementioned mixture being put into the two-dimensional mixing machine mixes with rock powdery emulsion explosive, the rotating speed that changes with per minute 25 mixed 5 minutes, and products obtained therefrom sampling inspection test meets national sector standard.
Claims (2)
1. rock powdery emulsive oily explosive and manufacture method thereof, it is characterized in that rock powdery emulsive oily explosive by rock powdery emulsion explosive, ammonium nitrate, lightweight machine oil in proportion (1: 0.16: 0.064) form to mix to make and form.
2. the manufacture method of rock powdery emulsive oily explosive according to claim 1, it is characterized in that accurately taking by weighing ammonium nitrate, lightweight machine oil in proportion earlier and mixing, accurately taking by weighing rock powdery emulsion explosive in proportion places the two-dimensional mixing machine in addition, mixture with aforementioned two things places the two-dimensional mixing machine again, the rotating speed that changes with per minute 25 mixed 5 minutes, promptly got rock powdery emulsifying oil part explosive.
