    Inżynierskie kryteria kształtowania wyrobisk podziemnych
    (Wydawnictwa AGH, 2010) Gałczyński, Stefan; Wojtaszek, Andrzej
    The material (physical) phenomena of roof pressure arch in soils and rock masses are considered in the paper. A small soil-coating bridge is presented as an example of this problem. Such factors as correct compression or natural consolidation of the soils form the load-carrying ability zone above the mined space. So, as result of this research, the real rock-mass arches are described as the save protections of the underground excavations. Some formulas to calculate the dimensions and a load capacity of these arches are given too.
