Meteorology & Airblast- Effects & Prediction
Airblast overpressure levels are influenced by the blast design and its implementation, and by the effects of meteorology that can increase airblast overpressure levels in the area surrounding a blast site by up to 20 dBL. The effect of both temperature and wind velocity is illustrated in this paper. An assessment of the degree to which air vibration levels will be affected by the effects of meteorology requires that temperature, wind speed, and wind direction be measured or evaluated at both surface level and at levels above the ground. This paper describes a system that has been developed for use in the Hunter Valley coal field in Australia, that provides more accurate meteorological data that may be used for the prediction and assessment of environmental effects such as noise,dust control, and gaseous emission as well as airblast overpressure. The system permits the effect on airblast overpressure levels of meteorological conditions existing at the time to be immediately evaluated, and permits the meteorological effect on airblast overpressure levels that will result later in the day to be predicted.
