长沙矿山研究院和武钢大冶铁矿经过几年的试验研究,试制成功一种浆状防水炸药。现已在大冶铁矿进行了七次生产试验,使用药量25吨,爆破矿石量5.5万吨,效果较好,再加改进后可以全部代替胶质(硝化甘油)炸药。浆状炸药的主要成份是硝酸铵和梯恩梯(含量分别为62％和10～15％)并混了16％左右的水和一些胶结村料,借以形成浆糊状,并具有良好的流动性。抗水性能的关键是胶结材料。该院曾经试验了58种胶结剂,几种助胶剂和十几种增塑剂,最后选定了一种野
Changsha Institute of Mining and Iron and Steel, Daye Iron and Steel, Wuhan Iron and Steel After several years of experimental study, trial success of a slurry-like waterproof explosives. Has been carried out in Daye Iron Mine seven production tests, the use of 25 tons of doses, the amount of blasting ore 55,000 tons, the effect is better, after all can be improved instead of plastic (nitroglycerine) explosives. The main components of the slurry explosives are ammonium nitrate and TNT (content of 62% and 10 ~ 15%, respectively) and mixed with about 16% of water and some cementitious materials to form a paste, and has good fluidity. The key to water resistance is cementing materials. The hospital has tested 58 kinds of cementing agent, a few kinds of plasticizers and a dozen plasticizers, and finally selected a wild
