| 摘要 |
The present invention relates to a HANFO explosive consisting of a mixture of at least one nitrate-oil explosive (ANFO-type) and at least one water-in-oil explosive, and a method for its manufacture. The oil of the ANFO part contains 0.3-7.0 weight % based on the weight of the oil component of the oilsoluble elastomer having a viscosity average molecular weight of 30,000-5 million, preferably 900,000-2.5 million. The manufacture of the HANFO explosive can be carried out by first adding an oilsoluble elastomer to the oil of the ANFO-type explosive, then mixing the oil with sodium-, ammonium- and/or calcium nitrate and then mixing this mixture together with a water-in-oil emulsion explosive. The HANFO explosive can be applied both in bulk and cartridged form.
