Zusammenfassung: | The invention discloses a novel antistatic and spontaneous combustion and explosion preventing sulfide mining emulsion explosive charging method. The method includes the steps of drilling a hole, putting a charging device, filling an annulus between the charging device and the drilled hole, and putting and detonating an explosive and filler. The method has the advantages that a heat-resistant adhesive is applied in the emulsion explosive charging method from the perspective of physical isolation, the explosive is prevented from directly acting on the interfacial surface on rock through a flexible material, the rapid energy diffusing is restrained in the heat radiation conduction process, and the influences of heat on sulfide ore are reduced; and then, pure cotton cloth is selected as the filling material between the charging device and the drilled hole in the emulsion explosive charging method, and by means of the three selected materials: an inner package, an outer package and the heat-resistant adhesive for |
