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.
Seismograph Analysis Eliminates Complaints
As mining encroaches on neighboring properties, the need to develop a vibration monitoring program became paramount.
Signature Hole Analysis & DigiShot® Plus Reduce Blasting Complaints
Matching delay firing times to the local geology eliminates neighbor complaints while improving productivity.
Signature Hole Analysis for Vibration Control
The challenge for this mine is coming up with delay timing that gives optimum performance without exceeding the limit of 5 inches per second PPV at the well.
Staying within Extremely Restrictive Vibration Limits without Increasing Costs
The movement of active mining to a new area has brought vibration perception to a new group of very expensive subdivisions. Complaints to state regulatory agencies have resulted in concerns over the possible suspension of the mining permit for this key customer.
Sub-drill Reduction to Aid in Vibration Control
Unacceptable peak particle velocity prompts change.
TITAN XL 1000 G Used to Eliminate NOx
Products that have shown to reduce NOx generation are typically lower density products than what is often used for cast blasting. The lower density results in less energy and the effective cast benefit is reduced. The goal is to find a product that will shoot clean and evaluate the cost versus cast benefit.
TITAN XL 1000 Yields Excellent Results
Many of the quarries are located very close to populated areas. The primary mineral deposits in this region is limestone and much of it is well laminated with a significant amount of cracks and seams in the formations.
TITAN XL for Wet Blasting Conditions
TITAN XL emulsion was utilized as a water resistant product that could be chemically gassed to various lower densities. Instead of the 1.30 gm/cc density of the 50/50 blend, TITAN XL was brought down to 1.10 gm/cc. The product is pumped through a hose placed in the hole. This eliminates the need to de-water the boreholes.
Vibration Modelling and Analysis Underpins Feasibility Study Accuracy
Vibration modelling was use to enable accurate mine planning and support the feasibility study for an African mining project. This work formed an essential part of the mine planning aspect in the final feasibility study.
