摘要
为了研究不同能量测试方法对工业炸药能量测试结果的影响,分别采用爆热、铅壔法和水下爆炸法测量了几种典型工业炸药样品的能量。结果表明:3种测试方法都能用于评价炸药的能量水平,其中爆热和水下爆炸法能直接得到样品的能量值,水下爆炸法适用于大药量样品的能量测试要求。水下爆炸试验结果表明,参比TNT药柱的总能量为3.410mJ/kg,粉状乳化炸药的总能量为3.758mJ/kg,1号和2号岩石乳化炸药的总能量分别为3.411mJ/kg和3.182mJ/kg,二级和三级煤矿许用乳化炸药的总能量分别为3.021mJ/kg和2.947mJ/kg,这5种工业炸药的TNT当量分别为1.10、1.00、0.933、0.886和0.864。水下爆炸测得的5种工业炸药能量为爆热测量值的76.1%～78.8%。
The energies of five typical industrial explosives are measured by blasting heat device, lead blocks and un- derwater explosion test systems to study the differences brought by using different testing methods. The results show that all the three testing methods can be used to effectively evaluate the energy level of industrial explosives, energy values can be directly generated by detonation heat or underwater methods, and the underwater explosion method can meet with the re- quirement for a large load test. Underwater explosion test resuhs show that the energy of reference TNT charge is 3. 410 mJ/kg, while the energies of powdery emulsion explosive, 1# and 2# rock explosives, and level 2 and level 3 permissible explosives are 3. 758 mJ/kg, 3.411 mJ/kg, 3.182mJ/kg, 3. 021 mJ/kg and 2. 947mJ/kg, respectively. The TNT equiva- lences of these five samples are 1.10, 1.00, 0. 933,0.886 and 0.864. The energy values of the samples measured by un- derwater explosion are 76.1% -78.8% of these by detonation heat.
