Abstract: This article presents the results of field tests of two-component mixtures of sodium chlorate as an oxidizer with solid combustible components. A method for calculating percentage ratio of the mixture components for a zero oxygen balance and the field tests results are described. The fact of breaking an oversized rock by a blasthole charge consisting of the test composition with a single DShE-6 shock tube as a primer along the entire charge was used as a criterion to asses the performance of this composition in industrial applications of dimensional stone quarrying or in secondary breaking. It has been established that the use of sodium chlorate mixtures with solid combustible components can be commercially used both for dimensional stone quarrying and for secondary breaking. Further research into the proposed compositions involves increasing the number of field tests to be performed to assess their characteristics. Adding a third component to two-component mixtures to boost the energy performance of the compositions seems highly promising. The protecting properties of the investigated compositions are of a particular interest.
Keywords: oxygen balance, two-component mixtures, gas generators, fuel-oxidizer mixture, universal gas-generating element, secondary breaking, dimensional stone quarrying, blasting operations
