Experimental methods for the estimation of the fluidity of rock expanded ammonium nitrate explosive

Fluidity of rock expanded ammonium nitrate explosive is analyzed from essential structure characteristics and compositions of this kind of explosive. Based on research practice, four methods for the test and evaluation of the fluidity of expanded ammonium nitrate explosive are proposed. It is shown from practical application that dynamic measurement system are feasible and simple method for measuring and evaluating of the fluidity of expanded ammonium nitrate explosive.
