Potential of Airblast Overpressure and Ground Vibration from Quarry Blasting to Increase the Frequency of Rockfalls on Mt. Coonowrin
Mount Coonowrin located in the Sunshine Coast hinterland north of Brisbane, is one of a scattered group of peaks and hills that constitute the Glasshouse Mountains and which is protected within the Glasshouse Mountains National Park. Concern about visitor safety in relation to rockfalls on the mountain were supported by the results of two geotechnical studies and led to the closure of this sect...
متن کاملRcs Prediction from Planar Near-field Measurements
It is well-known that, at low frequency, far-field RCS can be measured using a suitable implementation such as outdoor range or large anechoic chamber. The aim of this paper is to propose a new algorithm to predict RCS from near-field measurements. The comparison between RCS values obtained from the proposed method and those obtained from direct far-field values shows a good agreement between t...
متن کاملAn Assessment of Blasting Vibrations: A Case Study on Quarry Operation
Problem statement: One of the major environmental concerns related to blasting operation in mining and civil engineering projects is ground vibration. Approach: This study presented an assessment of ground vibrations caused by the blasting experiments at a marlstone quarry in northern Italy. The primary goal of this study was to determine the vibration level in order to protect dwelling area ad...
متن کاملApplication of simulated annealing for optimization of blasting costs due to air overpressure constraints in open-pit mines
Estimating the costs of blasting operations is an important parameter in open-pit mining. Blasting and rock fragmentation depend on two groups of variables. The first group consists of mass properties, which are uncontrollable, and the second one is the drill-and-blast design parameters, which can be controlled and optimized. The design parameters include burden, spacing, hole length, hole diam...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
