Effect of variations in the geologic data base on mining at Yucca Mountain for NNWSI
Description
This study was conducted to assess the impact of the known geologic factors and their variations at Yucca Mountain on the mining of the underground repository. The repository horizon host rock was classified according to the Norwegian Geotechnical Institute Tunneling Quality Index, which, in turn, qualified the range of ground support for the geologic and hydrologic conditions in the proposed repository area. The CSIR Classification System was used to verify the results of the NGI System. The expected range of requirements are well within normal mining industry standards and unusual or expensive ground support requirements are not expected to be required at Yucca Mountain. The amount of subsurface geologic information on Yucca Mountain is limited to data from a few drill holes. Variations in the existing data base are probable and should be provided for in the conceptual designs
