When considering the scale of the rock massif to solve a specific rock problem, it is necessary to consider the structure of the massif within this scale (volume). If the structure is homogeneous within the scale of the massif, the solution can use existing ideas about the properties of rocks in the massif and the scale effect. A homogeneous massif can be composed of micro-heterogeneous “mother” elements. In this case, consideration of rock strength characteristics is associated with statistical characteristics considered in laboratory tests of rock properties. This mathematical apparatus can be important during the selection of rock massif that could be appropriative enough for location of fallout shelters for protection of civilian population against the effects of Nuclear Weapons.

New calls for global security today, since operations the era of uncontested military superiority of western forces is fading and western response can't simply be to avoid operating in these environments but we should start to think about essential to protection of our potential in industry, population and infrastructure. It brings us back to refitting of rock massifs for fallout shelters requires an increasingly better knowledge of the composition, internal structure, geometry and depth extent of the individual rocks. This paper focuses on the long-term strength of a wide range of rock types that can be refitted for shelters.
