protective reinforcement Explanation: ausbau = reinforcement (as I would presume we are talking about reinforcing the mines) sicherung = securing, protection, safeguard... My guess would be you are looking at some sort of reinforcement structure within the mine shaft? If so, this might work. PONS, Expert & University Edition, 2000 |

(protective)support structure Explanation: In early tunnels, timber was used for the initial or temporary support, followed by a permanent lining of brick or stone masonry. Since steel became available, it has been widely used as the first temporary stage or primary support. For protection against corrosion, it is nearly always encased in concrete as a second stage or final lining. Steel-rib support with timber blocking outside has been widely employed in rock tunnels. The horseshoe shape is common for all but the weakest rocks, since the flat bottom facilitates hauling. By contrast, the stronger and more structurally efficient circular shape is generally required to support the greater loads from soft ground. 208.154.71.60/bcom/eb/article/printable/5/0,5722,127665,00.html - (excerpt from the Encyclopedia Britannica) Ernst offers for Schildausbau: shield-type support Schildbauweise(tunnel) shield driving method see also: Examined different methods for mining steeply deepening thick coal seams.
