Test plan: Intermediate scale borehole test--WIPP in situ testing

Technical Report ·
OSTI ID:6811909
This Intermediate Scale Borehole Test is in response to a request by the WIPP Panel of the National Academy of Sciences to investigate influence of scale (i.e., the size of an underground opening) effects on the creep closure of a natural salt deposit, in situ. The purpose of this intermediate scale test is to evaluate the possible influence of test scale on the creep response of salt. The results are to be usedas partial input to the resolution of the discrepancy between calculated and measured in situ closures. The test consists of an instrumented, large diameter, horizontal borehole emplaced in the existing pillar between Rooms C2 and C1. The depth of the core hole will be at least 9.2 m (30 ft). Because most of the instruments will be emplaced prior to drilling of the intermediate scale borehole, the instruments will monitor the changes in ground displacements and stresses as the borehole is drilled.
