What type of rock mass classification was applied in the construction of the El Teniente mine tunnels in Chile?
A. Rock Mass Rating (RMR)
B. Uniaxial Compression Index
C. Soil Bearing Ratio
D. Standard Penetration Test
Answer: Option A
Solution (By Examveda Team)
The Rock Mass Rating (RMR) system was used for tunnel support design in El Teniente mine. It evaluates rock quality based on strength, joint spacing, groundwater, and other parameters.This Question Belongs to Geological Engineering >> Case Studies And Applied Geological Engineering Projects
