Geology always plays a factor, sometimes in such a way that perimeter control might not lead to better results of an individual blast. However, when used globally over time, perimeter control design methods can decrease the overall cost of an operation significantly. https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/bac72ec2-7332-4c92-9cf9-3f7f1045f713/Picture1.jpg Posts - Underground Perimeter Control Basics The location and loading of the perimeter holes (roof and wall holes in image above) can be adjusted for post-blast or pre-blast perimeter control methods. https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/8383bc04-c99a-4242-b913-3631eaa22520/Perimeter+Control+Comparison.png Posts - Underground Perimeter Control Basics - Make it stand out Data taken from a seismic refractive survey on backbreak at the University of Missouri-Rolla by Dr. Paul Worsey. https://tbredblast.com/posts/blastvibration7 monthly 0.5 2023-11-01 https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/353cf228-d739-4626-a604-31209aef8d71/blasting+limits.png Posts - Blast Vibration Basics Post #7 - Make it stand out Report of Investigations 8507 Safe Levels of Blasting Vibrations for Residential-Type Structures [Siskind et al., 1980] https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/1697386471120-04SDT2P1MEX3Y3MY62S9/ablc.jpg Posts - Blast Vibration Basics Post #7 https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/1697386471549-V5TYA99VHS8JNY5TZW18/ablc2.jpg Posts - Blast Vibration Basics Post #7 https://tbredblast.com/posts/blastvibration6 monthly 0.5 2023-10-15 https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/6e7de435-ac55-4e88-a40a-929b1be072dd/structure+response.png Posts - Blast Vibration Basics Post #6 - Make it stand out Depiction of structural response to blast vibrations [Siskind et al., 1980).

If you ever worked on this science project at home, you know that the wire is coiled around the nail and connected to two battery terminals, like the image on the left. When connected to the battery, current will be introduced to the wire. The current in the wire creates a magnetic field, which then polarizes the nail and makes it magnetic. A geophone sensor operators with the same concepts. The coil moves along a magnetic cylinder. But because the cylinder is magnetic, unlike the nail, the magnet creates a current in the coil. The data logger measures the current and converts it to particle velocity. source: http://www.stefanklocek.com/simple-electromagnet/ https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/78a3f300-8849-4621-b5aa-7a0c66a219ea/accel.jpg Posts - Blast Vibration Basics Post #3 - Make it stand out Typical ICP® Accelerometer (source: https://www.pcb.com/resources/technical-information/introduction-to-accelerometers) https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/86d5e3c1-f547-4e04-a7cc-535b740dc837/mems.jpg Posts - Blast Vibration Basics Post #3 - Make it stand out MEMS variable capacitive DC accelerometer construction (source: https://www.pcb.com/resources/technical-information/mems-accelerometers) https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/559310f7-34fb-4ac7-9603-fd58bbc4585e/IMG_7598.jpg Posts - Blast Vibration Basics Post #3 - Make it stand out ShotTrack’s new ViB-Nano accelerometer. https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/aa9a5166-a5ed-4683-ac4d-95ce8f67f98f/2022-isee-performance-specifications-for-blasting-seismographs+%281%29.jpg Posts - Blast Vibration Basics Post #3 - Make it stand out Sample amplitude-versus-frequency calibration response graph (source: 2022 ISEE Performance Specifications for Blasting Seismographs). https://tbredblast.com/posts/blastvibration2 monthly 0.5 2023-07-04 https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/a6fee525-357a-4db7-a6bc-94c71cb25bc6/SGx2.jpg Posts - Blast Vibration Basics Post #2 - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/9a21bfff-835c-4aa4-98b7-f7954d60ea03/bobber.gif Posts - Blast Vibration Basics Post #2 - Analogy Particle velocity is often compared to a floating bobber. If you throw a rock into a pond next to a bobber, waves or ripples will emanate out from where the rock impacted. The impact of the rock is analogous to a blast and the waves are analogous to blast vibrations. Blast vibrations radiate out from a blast, the same as the ripples on the pond. The bobber can be compared to a seismograph’s geophone. The bobber is moving in one location; wherease, a geophone measures vibrations in one location. The velocity that a bobber moves up and down is analogous to the particle velocity of a vibration (the velocity that the geophone moves up and down or side to side when a vibration passes). The distance the bobber moves is displacement, which is not measured by a geophone, but it can be calculated using the particle velocity and frequency (see below). The frequency is number of times that the bobber moves up and down in one second.

In this analogy, the hammer hitting the nail is the source of the vibration. If you place your hand on the wall, you can feel the vibration of the hammer hitting the nail even though the vibration doesn’t damage your house. You can also hear it. A blast is analogous to the hammer hitting the nail. The blast causes vibrations in the ground and the blast can be heard by those nearby. https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/9fb7298f-8945-49f3-b8ca-f584baaffb26/Olofsson+Vibrations2.jpg Posts - Blast Vibration Basics Post #1 - Make it stand out Source: Applied Explosives Technology for Construction and Mining by Stig Olofsson https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/4fa6f136-e1a0-4044-bf0e-1dba7649c7e0/Mag-Energy-Freq-sm.gif Posts - Blast Vibration Basics Post #1 - Make it stand out Source: United States Geological Society (https://www.usgs.gov/programs/earthquake-hazards/earthquake-magnitude-energy-release-and-shaking-intensity) https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/26a6d855-ca9d-415c-b04d-bf0e973fc7c5/Dowding+Vibrations2.jpg Posts - Blast Vibration Basics Post #1 - Make it stand out Compressive Wave (left), Shear Wave (center), and Rayleigh Wave (right).

He was active in the department in mucking, mine rescue, student design, and the SME and ISEE student chapters. Nathan started working for Morgan Worldwide Consultants (MWC) in Lexington, KY in 2010. In 2014, MWC was acquired by Respec, Inc out of Rapid City, SD. He continued working in Lexington for Respec until 2019 when he joined DynoConsult, the consulting team for Dyno Nobel, as a principal consultant. He left Dyno to pursue a longtime dream and form his own company in January 2023. Nathan’s career has been focused on drill and blast engineering and consulting. He has managed drill and blast projects for surface and underground mining and quarrying operations globally. He loves the opportunity to travel to a new site, meet new people, and work with new teams to improve their operational outcomes. https://images.squarespace-cdn.com/content/v1/62f262c52b74ee1d4cc3906c/2404c5bc-38a0-45cc-8979-4cbb2fe8aea6/Laura+Butler About Our Drill and Blast Engineers Laura Butler Laura spent a decade in Australia building a strong foundation in business support and operations.
