Explosives Charge Sequence and Vibrations
This paper looks at the influences of explosives charge sequence on blast vibrations. The hole to hole timing is kept constant while the order of the charges is changed.
Facility Enhancement for Coal-Methane Explosion Research
The abstract looks at the drilling pattern, blasting and fragmentation to develop a methane coal dust explosion facility.
Florida Mining Blast Vibration Study Part 1: Do RI8507 Vibration Limits Apply in Florida?
This document, part 1 of 4, provides a summary of the USBM's research used to develop the vibration limits defined in RI 8507 and whether those limits apply to Florida.
Florida Mining Blast Vibration Study Part 2: Current Regulations in Florida
This document, part 2 of 4, provides a review of current blast vibration regulations in Florida.
Florida Mining Blast Vibration Study Part 3: Data and Analysis Review
This document, part 3 of 4, provides a review of blast vibration data collected in Florida and whether or not the USBM RI 8507 blast vibration limits are applicable to Florida.
Florida Mining Blast Vibration Study Part 4: Conclusions and Recommendations
This document, part 4 of 4, provides a review of conclusions and recommendations produced by the authors.
Fragmentation Driven Continuous Improvement Process
The paper will introduce the tools, the methodology of turning the data into information and then knowledge, placing the information in the correct location in the process, assigning the information the correct weight (creating a balanced SA) identifying opportunities for improvement, the decision logic and the CI loop.
Hemispherical Charge Comparison to Kingery-Bulmash
The report compares the observed blast parameters from a test series of hemispherical Composition C-4 surface detonations with the predicted blast parameters from the Kingery-Bulmash Blast Parameter Calculator. Differences between the experimental and predicted values are reconciled through analysis and discussion of testing conditions, instrumentation setup and scaling methods.
