Claims
- 1. In an aqueous explosive composition which comprises at least one inorganic oxygen-supplying salt, at least one fuel and at least one thickener, the improvement according to which the composition has a water content of from 5 to 15% by weight, a content of not less than 3% by weight hydrocarbon oil and from 0.5 to 5.0% by weight of a water soluble lignosulphonate, said composition being free from self-explosive matter, nitroderivatives, nitric acid esters and chlorinated hydrocarbons.
- 2. An aqueous explosive composition as in claim 1 wherein the oxygen-supplying salt is selected from the group consisting of ammoniumnitrate, sodium nitrate, potassium nitrate, calcium nitrate and mixtures thereof.
- 3. An aqueous explosive composition as in claim 1 wherein the hydrocarbon oil is a petroleum fraction normally designated as a fuel oil.
- 4. An aqueous explosive composition as in claim 1 wherein an additional fuel is selected from the group consisting of particulate aluminum, magnesium, silicon and alloys or mixture thereof.
- 5. An aqueous explosive composition as in claim 1, wherein the thickener is selected from the group consisting of guar gums and xanthan gums.
- 6. An aqueous explosive composition as in claim 1 wherein the water soluble lignosulphonate is selected from the group consisting of ammonium, sodium, magnesium and calcium lignosulphonate with or without a content of carbohydrates originating from the process producing the lignosulphonate.
- 7. An aqueous explosive composition as in claim 1 wherein the thickener is crosslinked by means of an agent comprising a compound of a heavy metal from the periodical system group 4, 5 and 6 in its highest valency.
