crater theory
Crater theory defines an optimum burden or distance to a free face at which a spherical explosive charge is buried and produces the greatest volume of broken and excavatable rock. This distance is unique based on rock type and explosive type. The theory also defines the critical depth or spherical charge buried depth at which surface disturbance is barely detectable, resulting in slight surface mounding and minor cracking.
