In this peper, the fire & explosion accident in the production of AN explosives are analyzed in detail.

Simple Wind-driven ANFO Detonator Loader;

Test of Blasting Funnel on Denaturalizing ANFO;

Analysis on the Major Effective Factors of the Performance pf WBN Tacky Granular ANFO;

This thesis studied the coal powder application effect in ANFO explosive, determines the prescription of the ANFO explosive with coal power,and analyzes economical profit of its application by means of theoretical analysis and experiments.

Theis paper described the experimental research into the cap sensitivity classification and detonation velocity of the tackiness-increased prilled ANFO explosives in the various confined conditions.

The addition of compound promoter in the production of AN-TNT explosive enhances apparently the drying and pulverizing effect of Ammonium Nitrate(NH_4NO_3),improves the product properties and also solves the problem of moisture absorption and agglomeration of pro-duct during the storage period.

A new type of seismic charge filled with expanded ammonium nitrate explosive isintroduced.

The characteristics of expanded ammonium nitrate explosive and its continuous production process were introduced in this paper.

<Abstrcat> The main ammonium nitrate explosives produced in China, and a tendency for the improvement of industrial explosives in China are discussed.
