Explosive Type Selection with Respect to the Ventilation Cycle Duration

Extensive measurements of the ambient air quality have been conducted in the past years during excavation of road tunnels situated on the mountainous sections of the future Croatian highway Zagreb – Split. The objective of these measurements was to estimate the worker exposure to toxic gases. Since conventional mining methods have been used for excavation of the tunnels (drilling and blasting), as well as various types of explosives and initial systems, the impact on the workplace environment by toxic gases produced from blasting was also examined. In order to reduce the amount of toxicants in the workplace atmosphere, the field method for selection of the most appropriate types of explosives in the blast charge was developed.
