摘　　要：文章通过对国内现有煤矿用粉状铵梯炸药及针对粉状铵梯炸药的缺陷而研制的粉状炸药抗爆燃性的实验研究,分析了炸药爆燃引燃的理论基础和引燃条件。结果表明,传统的铵梯炸药的抗爆燃性最差;铵梯炸药中木粉经过改性或取消木粉可以显著降低硝铵类炸药爆燃发生的可能性,粉状乳化炸药的抗爆燃性最好。In this paper, the measuring method on the new deflagration has been designed, The anti - deflagrability of the powdery explosivc contained ammonium nitrate and trinitrotoluene for coal mine and the new powdery explosives are researched, The theory base and igniting condition of explosive deflagration are analyzed. The results showed that the anti- deflagrability of the traditional powdery explosive contained ammonium nitrate and trinitrotoluene for coal mine are worst, Improved or canceled the wood powder in the powdery explosive contained ammonium nitrate and trinitrotoluene for coal mine can reduce anti - deflagrability, The anti - deflagrability of powdery emulsion explosive are best,
