Problems solved by technology

It can only provide feedback and guidance for the next batch of production, but cannot guide production in time
Sometimes the ammonium oil explosives will have no oil, resulting in a blind shot, not only does not play the role of explosion work, but also it is very dangerous to deal with the blind shot in the later stage
The direct economic loss reaches 4200 yuan / ton; at the same time, there are also great unsafe factors hidden

Embodiment 1

[0033] 1) Determination of saturated oil absorption of porous ammonium nitrate particles:

[0034] Take porous ammonium nitrate particles and weigh 20.0g, place them in a clean and dry 150ml beaker, add enough diesel oil to soak for 15min, transfer the sample to a glass crucible filter, and place the sample in a vacuum greater than 2.7×10 4 Under the condition of Pa, perform suction filtration for 10 minutes until no oil drips down. The sample after the suction filtration is transferred to a clean and dry beaker of known quality and weighed (accurate to 0.1g), to obtain 21.8g of porous ammonium nitrate particles after fully absorbing oil;

Abstract

The invention discloses a method for measuring the component proportion of an ammonium nitrate fuel oil mixture by virtue of the saturation oil absorption rate of a raw material. The method comprisesthe following steps: (1) weighing porous ammonium nitrate particles with mass M, soaking the porous ammonium nitrate particles into diesel oil so as to reach a saturation state, carrying out suction filtration and weighing, so as to obtain mass M1 of the porous ammonium nitrate particles after oil absorption, wherein the saturation oil absorption rate phi of the porous ammonium nitrate particles is equal to (M1-M) / M*100%; (2) weighing an ammonium nitrate fuel oil mixture sample with mass M3, soaking the ammonium nitrate fuel oil mixture sample into diesel oil so as to reach a saturation state,carrying out suction filtration and weighing, so as to obtain mass M4 of the ammonium nitrate fuel oil mixture sample after oil absorption, wherein the porous ammonium nitrate particles used in the ammonium nitrate fuel oil mixture sample and the porous ammonium nitrate particles in the step (1) are the same batch; and (3) calculating according to a formula M2={(phi+1)M3-M4} / (phi+1), wherein theproportion w of the diesel oil in the ammonium nitrate fuel oil mixture sample is equal to M2 / M3*100%. According to the method for measuring the component proportion of the ammonium nitrate fuel oil mixture in a short time, the quality of the ammonium nitrate fuel oil mixture is guaranteed, the power capability of the ammonium nitrate fuel oil mixture is improved, and the explosion effect is improved.

Description

technical field [0001] The invention relates to a method for determining the component ratio of ammonium oil explosives by using the saturated oil absorption rate of raw materials, which belongs to the technical field of explosive technology and equipment. Background technique [0002] At present, coal is still the main body of industrial energy, and its mining technology is not the same. It is an indispensable link in the coal mining process to use the energy released by the explosion of explosives to realize blasting. Improving explosive performance, increasing safety and reducing production costs are the main research directions for continuous improvement and development of industrial explosives. Ammonium oil explosives have the advantages of low cost, abundant sources of raw materials, simple production process, flexible control, low detonator sensitivity, and high safety. [0003] The components of ammonium oil explosive mixed on site are composed of porous granular a...
