Abstract

Iz 28 izvještaja o ispitivanju kakvoće zraka i mikroklimatskih uvjeta u radnom prostoru radilišta 11 tunela, uzeti su podaci o koncentracijama štetnih i opasnih plinova, o količinama eksploziva, protoku zraka na izlazu iz ventilacijske cijevi i udaljenosti izlaza ventilacijske cijevi od čela tunela. Tuneli su izrađeni tehnologijom bušenja i miniranja. Nakon izvedenih miniranja mjerene su koncentracije štetnih plinova na radilištu tunela. Provedena je analiza utjecaja količine eksploziva, protoka zraka i udaljenosti ventilacijske cijevi od čela na ukupnu koncentraciju štetnih plinova i vrijeme razrjeđenja.

Abstract: Data from 28 reports on air quality and micro climate in workplace of 11 tunnels was analyzed in this work. This includes concentration of gases, the amount of explosive, air flow from the ventilation duct, and distance of the ventilation duct from the tunnel excavation face. Tunnels are made by “drill and blast“ technique. Blasting was observed as a source of of harmful gasses in tunnels workplace. Analysis of influence of the amount of explosive, air flow and distance of ventilation duct from the tunnel excavation face on total concentration of harmful gasses and dilution time was conducted.
