摘　　要：研究一种以低爆速膨化硝铵炸药为主装药的低爆速震源药柱。用自敏化改性膨化硝酸铵为氧化剂的低爆速膨化硝铵炸药的配方为（质量分数）：膨化硝酸铵83％～87％、木粉3．0％～4．0％、复合油2．0％～3．0％、高能添加剂4．0%～5．0％和稀释剂6％～8％。研究表明，低爆速膨化硝铵震源药柱具有稳定的爆炸性能和优良的安全性能，其爆速为2200～2500m·s^-1，装药密度0．78～0．82g·cm^-3，各种环境条件下的起爆率均为100％。A kind of low detonation velocity seismic explosive column charged with low detonation velocity explosive in which self-sensitized and improved expanded ammonium nitrate is oxidizer was investigated. This kind of low detonation velocity explosive is composed of 83 % - 87%expanded ammonium nitrate, 3.0 %-4.0% wood powder, 2.0-3.0% composite fuel oil, 4.0%-5.0% high energetic additives and 6%-8%; dilution agent. The results show that low detonation velocity expanded ammonium nitrate seismic explosive column possesses good explosive property and safety. The detonation velocity of this kind of low detonation velocity seismic explosive columns corresponding to charge density 0.78～0.82g·cm^-3 is 2200～2500m·s^-1, and the initiation percent in various surrounding condition is 100%.
