Abstract
The present invention relates to a coal mine permitted ammonium TNT oil explosive and its production method. Its composition and contents are: ammonium nitrate, wood powder, oil phase, TNT 1.5-2.5%, compound flame-elimianting ageng 10-20% and surfactant 0.1-1.0%, in which the flame-elimianting agent is formed from one or several kinds of three groups of compounds of alkali metal or alkaline earth metal nitrate, ammonium halide salt and alkali metal or alkaline earth metal halide, and its surfactant is formed from one or several kinds of alkylamine salt whose carbon chain is 12-18, sodium lauryl sulfate, stearic acid and dodecyl alcohol acyl phosphate, etc.
Description
Technical field [0001] The invention relates to mine blasting equipment, in particular to a coal mine blasting equipment that meets the requirements for use in an underground coal mine where there is a gas and coal dust explosion hazard, has stable detonation performance, good anti-deflagration tendency performance, high storage stability, and low TNT content. Permitted ammonium ladder oil explosives, and methods of making such explosives. Background technique [0002] At present, the permitted coal mine powder explosives used in coal mine blasting in my country are mainly ammonium ladder explosives permitted in No. 2 and No. 3 coal mines. The content of the explosive TNT is high, reaching about 10%, which not only seriously endangers the health of workers, but also seriously pollutes the environment. It is necessary to reduce the content of TNT in coal mine explosives. [0003] Existing rock-type low-titanium-titanium fuel explosives are available in existing patent appli...
