  • Why do companies blast?

    Utilizing blasting remains the most economical method for rock fracturing, reducing expenses in producing consumer goods like electricity, sand, gravel, concrete, aluminum, copper, and various items derived from mined resources. The age-old adage "If it can't be grown, it has to be mined" holds true even today.

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

    Blasters possess the expertise to compute the efficiency of the energy they deploy. By utilizing precisely the amount of energy necessary for the specific task, one can be confident that no excess energy is left to induce ground vibration damage to properties beyond the blast site.

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

    Ground movement is commonly detected using seismographs. The air blast generated by open-pit blasts and surface explosions can present a notable hazard, prompting the use of microphones to monitor the explosion's effects.

  • Is blasting going to damage my home or well?

    We follow strict safety standards for blasting determined by your state, the United States Bureau of Mines, and the Office of Surface Mining. These standards are scientifically tested and have been proven to protect structures from vibration.

  • Can blasting be done close to existing structures?

    Yes. Our company has many years of experience with technical blasting within proximity of structures. We have skilled employees who use various forms of vibration prediction. 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 before blasting to document the conditions of the structures through photography and videography.

  • How do we measure vibration?

    Eagle Rock Blasting has several seismographs and operators to measure vibration. The manufacturer calibrates these seismographs annually to ensure accuracy, and each seismograph has 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. Professionals carefully design all blasts, and results are predetermined.

  • Who needs to be contacted prior to blasting commencing?

    Before any blasting operations, we contact the local law enforcement, fire departments, and emergency response teams. Additionally, we communicate verbally and by letter with anyone within a 500-foot radius of the blasting site. 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. Blasting can actually be quieter than rock hammering and takes much less time. A typical blast duration is usually one to three seconds, while rock hammering can take hours or even days to achieve similar results.
