Abstract

The invention discloses a heavy ammonium nitrate fuel oil explosive. The explosive consists of the following raw materials in part by weight: 1 to 100 parts of mixture of porous granular ammonium nitrate and diesel oil, 1 to 100 parts of powdery ammonium nitrate fuel oil explosive and 0.5 to 1 part of water-resistant additive. A method for processing the explosive comprises the following steps of: starting a vertical mixer; adding the water-resistant additive into the mixture of the porous granular ammonium nitrate and the diesel oil; mixing the materials for 2 to 4 minutes; adding the powdery ammonium nitrate fuel oil explosive into the mixture; fully and uniformly mixing the raw materials to prepare the explosive; and packaging and warehousing the explosive. Compared with the prior art, the heavy ammonium nitrate fuel oil explosive has the advantages that: the dispersion performance of the heavy ammonium nitrate fuel oil explosive is improved, the charging operation during the blasting is more convenient, the initiation of explosion can be performed by using a normal industrial explosive coil, meanwhile, the density and the explosive capacity of the heavy ammonium nitrate fuel oil explosive are adjustable, and the explosive is favorable for blasting different rock stratums.

Description

A kind of preparation method of explosive
Technical field
The present invention relates to the industrial explosive field, specifically a kind of preparation method of explosive.
Background technology
Industrial explosive be modern industry development one of indispensable basic energy resource, titania-mica is used in China widely as a kind of of industrial explosive.The prescription of titania-mica mainly is to be formed through physical mixed by materials such as emulsion matrix, ammonium nitrate, diesel oil, additives.Emulsion matrix plays sensitization and increases the effect of titania-mica power, is used for surface blasting, and free-running property is poor, and it is low to increase powder charge difficulty and explosive sensitivity, needs detonation tool just can detonate.
Summary of the invention
Technical assignment of the present invention provides a kind of titania-mica.
Technical assignment of the present invention realizes that in the following manner this titania-mica raw material is made up of mixture, powdered ammonium nitrate-fuel oil explosive and the anti-water additive of ammonium nitrate and diesel oil, and the weight part proportioning of each raw material is as follows:
1~100 part in the mixture of ammonium nitrate and diesel oil; 1~100 part of powdered ammonium nitrate-fuel oil explosive;
0.5~1 part of anti-water additive;
Working method: start vertical mixing tank, add anti-water additive in the mixture of ammonium nitrate and diesel oil, remix added powdered ammonium nitrate-fuel oil explosive after 2~4 minutes, and with the even back of each raw material thorough mixing drug, the packing warehouse-in gets final product.
In the mixture of described ammonium nitrate and diesel oil, the weight ratio of ammonium nitrate and diesel oil is: 95.5: 4.5.
Described powdered ammonium nitrate-fuel oil explosive is bulking ammonium nitrate explosive or modified ammonium nitrate-fuel oil explosive.
Described anti-water additive is a kind of in W-Gum, wheat starch and the yam starch.
Titania-mica of the present invention is compared with prior art, improved the Diaspora Performance of titania-mica, be convenient to the operation of powder charge in the blasting process more, available common industrial explosive powder stick detonates, titania-mica density and brisance are adjustable simultaneously, help the explosion at different rock-layers.
