Stemming is used in blastholes to improve energy retention and confinement. Depending on which type and size of stemming material you use, it will have different relative densities. Using the design stemming height calculator, stemming relative density and volumetric calculations done by our calculator, you can calculate the mass of stemming required per hole or for the blast as a whole.
