Coal mining practice of Upper Silesia with regard to "elastic construction" in mines subject to extreme rock pressure; upper Silesian types of temporary and permanent lining and bracing of tunnels and mine galleries with special precast segmental blocks of concrete; unusually flat arched roofs are supported in this manner. See Engineering Index, 1928, p. 442.
