Abstract

Razvijanje željeznica imalo je važnu ulogu u ljudskoj povijesti. Omogućila je brojne promjene u ljudskom društvu tako što je povezala gradove kako društveno tako i ekonomski. Jedna od važnih sastavnica željezničke pruge je željeznički zastor. Željeznički zastor služi za ravnomjerno prenošenje opterećenja s tračnica i pragova na donji ustroj, sprječavanje uzdužnog i vertikalnog pomicanja kolosijeka te osiguravanje brzog otjecanja vode. Za izradu zastora koristi se kamen koji mora biti velike tvrdoće, otporan na mraz te ne smije upijati vodu kako bi sama željeznička pruga mogla pretrpjeti masu i brzinu s kojom se svakodnevno susreće. Za izradu takvog zastora najčešće se koriste magmatske stijene poput bazalta, gabra i dijabaza, a u slučaju njihove nedovoljne količine, mogu se koristiti i metamorfne stijene poput amfibolita te sedimentne stijene. Primjer petrografskih karakteristika bazalta (spilita) i dijabaza opisan je na uzorcima iz kamenoloma Bojna, Banovina. Uz pomoć GIS softvera napravljena je prostorna analiza pojavljivanja dijabaza i amfibolita na području Republike Hrvatske kako bi mogla poslužiti za brz pregled ovih stijena kao potencijalne mineralne sirovine za obnovu ili izradu novih željezničkih zastora.

Abstract (english)

The development of railways played an important role in human history. It enabled numerous changes in human society by connecting cities both socially and economically. One of the important components of the railway line is the railway curtain. The railway curtain is used to evenly transfer the load from the rails and sleepers to the lower structure, prevent longitudinal and vertical movement of the track and ensure rapid drainage of water. Stone is used to make curtains, which has to be very hard, resistant to frost and must not absorb water so that the railway itself can withstand the mass and speed it encounters every day. Igneous rocks such as basalt, gabbro and diabase are most often used for construction of curtains, and in the case of an insufficient amount of igneous rocks, metamorphic rocks such as amphibolite and sedimentary rock can also be used. An example of petrographic characteristics of basalts (spilites) and diabases is described using the samples from Bojna, Banovina. With the help of a GIS software, a spatial analysis of diabases and amphibolite occurrences was made in the territory of the Republic of Croatia in order to serve as quick overview of those rocks which could be used as potential mineral materials for the reconstruction or construction of new railway curtains.
