The Rocksplitter’s active mixture, which consists of sodium chlorate(V) (SC) and oil, is characterized by the lack of detonation capability and the presence of solid sodium chloride particles in the explosion products that reduce the volume of gas. The reduction of gaseous explosion products under certain conditions may be a disadvantage, reducing the effectiveness of Rocksplitter’s impact on the loaded rock mass, which may be a significant limitation in the use of this product. Replacing some of the sodium(V) chlorate(V) with ammonium nitrate(V) (AN) should partly eliminate this disadvantage. In this work, the results of research on selected detonation and explosive parameters of tertiary mixtures of SC - AN - oil are presented. The influence of grain size of AN was also investigated. AN was used granulated and ground. The ability to detonate, velocity of detonation and intensity of air blast waves in the functioning of the contents of individual components has been set.
