摘要

Arguably, some of the most restrictive statutory blast vibration requirements attached to mineral extraction operations can be found in the United Kingdom. Such limitations are, as a rule for the UK, stipulated together with a required statistical confidence that has to be observed in the blast design process in order to ensure total planning compliance. A key element in this procedure is the effect imparted by vibration data scatter from previous blasts as this becomes reflected in the site's operational standard error statistic and in turn directly influences the maximum instantaneous charge weights that can be justifiably employed. The greater the scatter, the lower the compliant charge weights become. With the onus on minimising the variables that can affect the outcome and with such restrictions appearing to become ever tighter, a great deal of interest has been generated as to the potential benefits that may be gained through the deployment of electronic detonators. It is commonly perceived that the inherent random timing scatter of conventional non-electric initiation systems is a major contributing factor to the inconsistencies observed and by design, these may be alleviated through such an alternative approach. In order to investigate this matter, the Minerals Industry Research Organisation (MIRO) under the terms of the UK Government's Mineral Industry Sustainability Technology (MIST) program has agreed to fund an industry wide fundamental study. Carried out by the Blasting and Environmental Research Group, The University of Leeds, England, this paper reports the initial findings in respect to blasting at limestone quarries. Such results highlight the benefits that can be achieved in terms of consistency, reduced data scatter and improved predictive capacity with tighter confidence intervals for full-scale production blasts.
