Abstract
The invention relates to an explosive mixed loading truck, a powdery ammonium nitrate fuel oil explosive for the explosive mixed loading truck and a method for preparing the powdery ammonium nitrate fuel oil explosive. Specifically, the explosive mixed loading truck is used for containing raw materials of powdery ammonium nitrate, liquid combustible agent, solid combustible agent and the like which are prepared through a ground station or containing the mixture of the powdery ammonium nitrate and the combustible agents, or, a transport vehicle is used for transporting the materials into the field explosive mixed loading truck. In an explosion field, the explosive mixed loading truck directly fills a finished product of the powdery ammonium nitrate fuel oil explosive which is prepared by mixing the powdery ammonium nitrate with the combustible agents into a blasthole. Because a medium which is prepared and transported through the ground station has low sensitivity, the safety degree of explosive production is basically improved, moreover, the explosive mixed loading truck is directly adopted to produce and fill, so that the labor intensity is reduced, the production efficiency is increased, and the explosive cost is lowered. Compared with a granular ammonium nitrate fuel oil explosive, the explosive power is improved, and the explosive cost is lowered.
