Cost of Blasting - Earthwork/grading engineering - Eng-Tips

2003-10-15  Rock blasting can cost anywhere from $3.00/m³ to $150/m³ depending on location in the world and location relative to buildings, etc. Small diamter drills (115mm and less) cost about $20,000 USD/month to operate. So figure $1000/day if you drill and $1500/day if someone else drills. Worldwide Explosives (stick powder) is roughly $2.20 - $7.00/kg.
