  • Why do companies blast?

    Blasting is the most cost-effective technique for fracturing rock, resulting in decreased production costs across a range of consumer goods, including electricity, sand, gravel, concrete, aluminum, copper, and other items sourced from mining activities. The age-old adage "If it can't be grown, it has to be mined" holds true even in the present day. Our rock blasting contractors are highly experienced in what they do and are happy to answer any further questions you may have.

  • When blasting is done near my property, what keeps my home or my well from being damaged by ground vibration?

    Our rock blasting contractors are experts at operating blasting machinery. They will only use the precise amount of energy necessary for the specific task so you can be confident that there is no excess energy left to create ground vibration damage to properties beyond the blast site.

  • How do you measure the ground vibration and air blast?

    To detect ground movement, our rock blasting contractors use seismometers to detect ground movement. The air blast generated by open-pit blasts and surface explosions can present a notable hazard, prompting the use of microphones and pressure gauges to monitor the explosion's effects.

  • Is blasting going to damage my home or well?

    Our rock blasting contractors follow strict safety protocols when conducting our work. For example, according to the CDC, employers and workers are required to dig a minimum of 5 feet away from utility lines. These standards, established by your state, the United States Bureau of Mines, and the Office of Surface Mining, undergo scientific testing and are validated to keep structures safe from vibrations.

  • Can blasting be done close to existing structures?

    Yes! Eagle Rock Blasting has many years of experience with technical blasting within close proximity of structures. We have skilled rock blasting contractors who use various forms of vibration prediction. In fact, we’ve completed projects within five feet of structures with no damage incurred.

  • What is a pre-blast survey?

    The survey is a standard procedure carried out before blasting. This will allow the rock blasting contractors to document the conditions of the structures through photography and/or videography.

  • How do we measure vibration?

    Our rock blasting contractors use seismographs and operators to measure vibration. The seismographs are calibrated annually by the manufacturer to ensure accuracy and also have a self-check mode that runs before monitoring.

  • Am I going to hear or feel the blast?

    Yes, vibration and noise are inherent by-products of a blast, all of which can be controlled to minimize human perception. All blasts are carefully designed by skilled professionals and carried out by our team of rock blasting contractors, with predetermined outcomes.

  • Who needs to be contacted prior to blasting commencing?

    Before any blasting operations, we make sure to contact the local law enforcement, fire departments, and emergency response teams. Additionally, our rock blasting contractors will communicate with anyone who is located within a 500-foot radius of the blasting site. This communication is done through verbal means and/or a letter. This is a standard procedure for any project that we undertake.

  • Why isn’t rock hammering or chipping used to excavate rock?

    Rock hammering is slow, inefficient, costly, and has the same inherent properties as blasting on a smaller scale. Our rock blasting contractors find that blasting is quieter than rock hammering and takes much less time. Additionally, in our experience, a typical blast duration is usually one to three seconds, while rock hammering can take hours or even days to achieve similar results.
