Industry explosive made from desensitively modified ammonium nitrate fertilizer, sawdust and diesel oil is confined in a 80mm×160mm×1mm iron cyl inder to determine its detonator sensitivity.

In order to make the powdery modified ANFO to replace the AN-TNT explosive truly in the performance and understand the relations between the particle size of AN and the mechanical sensitivity,the mechanical sensitivity of modified AN with different particle sizes is tested by referring to the standardization method GJB772A-97.

Study on Modified ANFO Explosive;

In this paper,some sensitivities of powdery modified ammonium nitrate(MAN) including sensitivity to impact,sensitivity to friction,sensitivity to detonator and sensitivity to electrostatic spark were tested.

Under solid mixture,the relationships between the contact angle of modified ammonium nitrate coated by oil and surfactant additive amount and between surfactant additive amount and explosive properties are studied.

In order to study electrostatic properties of modified ammonium nitrate dust(MAND),based on the continuous product line of modified ammonium nitrate explosive,the equipments for airflow transportation were simulated and the electrification of MAND in the airflow transportation process was detected.
