Controlling Vibration Damage
The ability of HotShot® electronic initiation system’s ability to maintain the integrity of highwalls was demonstrated in a test at Newcrest’s Telfer gold mine.
Conversion from Traditional Initiation to Modern Initiation
Inconsistent breakage & complaints from vibration off the blast events motivate two Indiana limestone quarry customers to convert from detonating cord and slider cast boosters to DigiShot® electronics and Spartan® cast boosters.
Expansion of Quarry Using TITAN® 1000 LD and DigiShot® Plus
Surrounded by numerous communities, the Graymont Marbleton Quarry was looking to expand its quarry number six.
Increased Production and Happy Neighbors
By using Signature Hole Analysis modeling to develop alternative timing sequences, Dyno Nobel was able to increase the blast hole diameter allowing for pattern expansion and an increase in blast rock per hole. Pattern expansion resulted in lower drilling costs, and timing sequences kept vibration levels low, while enabling the quarry to increase production per blast event while ensuring minimal off-site ground vibration to satisfy the local market demand for stone.
Minimizing Off Site Blast Effects
By using site-specific seismic modeling that determined optimum firing sequences on a shot by shot basis, off-site vibration effects were minimized and additional gains in overall blast efficiency led to better fragmentation, faster truck cycle times, reduced oversize, increased pattern geometry, elimination of decking and the ability to increase shot size.
New Alternatives for Pipeline Construction
Utilization of Signature Hole Analysis combined with DigiShot® electronic detonators demonstrated how close proximity blasting can be achieved even with very conservative vibration limitations.
Quick Shot Point Data Collection Improves Landowner Relationships
A concerted effort took place to convince additional land owners to allow exploration work to take place on their properties in order to expand the scope of the project. The companies involved realized the best way to expand the project was to show the landowners the success of the work being accomplished with minimal damage to the land. To make this happen they needed a system to monitor its efforts and provide data to show landowners actual results happening “next door”.
Reduced Blasting Complaints
At this Powder River Basin coal mine, pit development was moving blasting operations closer to an adjacent community. Blast event complaints and concerns over blast effects threatened to cause this western coal mine to look at radical changes to their blasting program.
As a result of using DigiShot detonators with alternative timing, vibration was reduced and dominant frequencies were increased. Improved energy utilization during the blast resulted in the elimination of decking, pattern expansion and a dramatic increase in blast size.
Reducing Regulatory and Liability Exposure
Taking advantage of the flexibility and precision of the DigiShot® electronic initiation system and using alternative timing sequences designed through signature waveform analysis, one northeast U.S.A. quarry operator was able to reduce peak particle velocity values by over 50%. Reductions in ground vibration were realized without the loss of productivity, blast size, or fragmentation.
