The method of manufacturing freeze proof rock expanded AN explosive through reducing the solidifying point of composite oil phase is introduced in this paper.

In this thesis, coating catalystic method are introduced to modify sawdust, and influences of modified sawdust on explosion properties of expanded ammonium nitrate explosive are investigated.

In order to investigate the thermal stability and thermal decomposition properties of a new kind of permissible expanded ammonium nitrate explosive,adiabatic thermal decomposition of No.

By analyzing the continualy mixing process for rock expanded ammonium nitrate explosive and the requirement of the component s determinate error at different conditions,in order to ensure the mixing proportion to meet with the process,the project was proposed in the paper.

Research on the Density Additive for Expanded AN Explosive;

In this paper,according to the low-density of expanded AN explosive,several methods to increase the density through the production technique and equipment adjustment based on the existing continuous production line are introduced.

In the paper,a higher power expanded ammonium nitrate explosive was made from the expanded ammonium nitrate,the wood powder,the composite fuel oil and some additives.

Because of its low cost,high efficiency,no toxicity and excellent explosion pro perties,the expanded ammonium nitrate explosive is used widely in China.

The expanded ammonium nitrate explosive modified by surface active process largely overcome main disavantages of power ammonium nitrate explosive.

The influence of rosin content in oil phase on the shock wave sensitivity of expanded ammonium nitrate fuel oil explosives(50% detonation distant) is vesearched by up to down method.

Through these microcosmic parameters,microcosmic interpretation on excellent shock wave sensitivity of expanded ammonium nitrate fuel oil explosives can be conducted.
