DRAGON – inovativan pristup bušenju tunela

Vađenje i uporaba mineralnih resursa zahvaljujući tehnologiji DRAGON

O ovome projektu

Izgradnja tunela uključuje iskopavanje nekoliko milijuna kubičnih metara stijena, koje često završe na odlagalištu otpada. Zahvaljujući tehnologiji DRAGON stijene se može analizirati i razvrstati na mjestu iskopa. Izdvajaju se vrijedni mineralni resursi za potrebe industrijskog procesiranja za dobivanje, primjerice, keramike i čelika.

European know-how drives Austrian project

Partners from across the continent contributed to DRAGON’s success
Robert Galler: proud to have worked with specialists from across Europe on the DRAGON project

The EU-funded DRAGON project has developed technology to gather information about properties of tunnel muck so that it can be recycled. Led by Robert Galler of Austria’s Montanuniversität Leoben, the project wouldn’t have been possible without the support of partners from across Europe. “DRAGON is the best example to show the importance of interdisciplinary exchange in Europe. It is excellent that this is promoted by the EU,” says Galler.

Austrian construction company PORR brought its tunnelling expertise to bear and British firm PE North West Europe supplied the software. Online analytical know-how was provided by German measurement technology specialist Indutech and the DRAGON technology was tested by German tunnel boring machine manufacturer Herrenknecht. Swiss company B+G was responsible for material management, while French construction materials expert Jacques Burdin also gave valuable input.

European grant provides big opportunity for young scientist

Austrian geology student conducts essential research for EU-backed project

Melanie Krüger is studying raw materials geology in the department of subsurface engineering at Austria’s Montanuniversität Leoben. For her thesis, she is conducting research on chemical analyses that are essential for the EU-funded DRAGON project.

The project has developed technology to gather information about properties of tunnelling debris quickly so that it can be reused. “I test the properties of tunnel excavation material, which is necessary to determine how it can be further used – as bulk material for example. It could thus play a very important role in the building materials industry in the future,” explains Melanie.

“The EU grant was definitely very important for implementing the DRAGON project”, adds the young scientist. “I believe that EU grants are very important for universities, as I would also like to be able to work with innovative projects such as DRAGON in the future, and thus have the opportunity to show my potential.”

Stijene iskopane iz tunela postaju korisne zahvaljujući projektu DRAGON

Oko 800 milijuna tona stijena iskopa se prilikom izgradnje tunela diljem Europe. Sveučilište Leoben u Austriji i ostali članovi konzorcija DRAGON razvili su tehnologiju za vađenje mineralnih resursa iz tih stijena. 

S pomoću digitalne analize stijene se može razvrstati na mjestu iskopa. Minerali se potom mogu procesirati u različitim industrijskim sektorima za dobivanje proizvoda kao što su cement, čelik, keramika i staklo. 

Postupak je ispitao projektni partner Herrenknecht. Troškovi projekta iznosili su 4,5 milijuna EUR i omogućen je sredstvima EU-a. 

„Zahvaljujući sredstvima EU-a uspjeli smo zajedno s našim europskim partnerima razviti inovativan tehnološki pristup kojim se omogućuje održiva uporaba vrijednog iskopanog materijala u industriji“ rekao je voditelj projekta prof. Robert Galler.
