Abstract

Abstract

Different additives were added to ANFO to enhance its detonator initiation sensitivity and work capacity. Based on the principle of the plate trace test, the test device and method were proposed to compare detonator initiation sensitivity and work capacity of ANFO containing additives. The results show that all the selected additives can improve detonator initiation sensitivity and work capacity of ANFO. Among these additives, Al and AP have stronger effects on the work capacity of ANFO than glass microballoon particles, AC foaming agent and NaNO2. The effect mechanisms of these additives were analyzed respectively.
