Calculadora de cantidades de perforación

For production reporting using measured inputs: drilled metres = holes × average length; tonnes = surveyed volume × density. Hours and shifts are productive equivalents for one rig, not elapsed calendar time.

Use the complete drilled length, including additional drilling, and net productive time. Surveyed volume and density must refer to the same in-situ rock. This tool reports drilling quantities; it does not design a blast or recommend explosive charges.
