Summary

Předmět je zaměřen na rozpojování hornin při ražení podzemních objektů tzv. klasickou technologií pomocí vrtacích a trhacích prací. Seznamuje se sortimentem prostředků trhací techniky, roznětem náloží a metodikou stanovování základních parametrů odstřelů. Dále je zaměřen na ražení a vyztužování podzemních děl. Seznamuje se stanovením základních parametrů pro ražení (velikost a tvar díla, posouzení geotechnických podmínek horninového prostředí) a výztužními konstrukcemi. Zejména seznamuje s klasickou technologií ražení s použitím vrtacích a trhacích prací, zabývá se rovněž problematikou mechanizovaného ražení výložníkovými stroji, tunelovacími stroji a razicími vrty. Je zaměřen na horizontální díla různého tvaru a velikosti, ražená v různých podmínkách (hloubka, účel, bezpečnost, anomálie horninového prostředí). Problematika ražení a hloubení svislých děl je probírána pouze okrajově. Student získá základní představu o technologiích ražení podzemních objektů s podrobnějšími znalostmi o tzv. klasickém ražení zejména liniových vodorovných děl (kolektorů, štol, tunelů). Získá základní znalosti pro stanovení komplexního technologického postupu s návrhem strojního a materiálového vybavení ražby, osády, určení technologických časů základních i pomocných operací razícího cyklu rezultující v časový harmonogram ražení. Naučí se dimenzi základních typů výztužních konstrukcí (dřevo, ocel, svorníky, beton). Součástí je i platná bezpečnostní legislativa při ražení v podzemí.
