A Mud Slurry Lining System “MSL” is invented as a new concept of CAES high pressure air storage. MSL give the prestress against RC lining with pressurized mud slurry injected the gap between rock and RC lining. Self-clogging function is required, because pressurised mud slurry does not leak into rock, and mud slurry pressure must be maintained.
Authors implemented laboratory test to verify the self-clgging property of mud slurry against grabity and antigravity direction under the maximum 3MPa pressure using artificial fracture specimen simulated rock mass. And the self-clogging charactoristics could be confirmed.This report shows the results.
