Abstract
One of Spokane Mining Research Center's projects is the development of engineering criteria for designing flexible liner backpacking systems for underground support. Until 3 years ago, the system advantages were all theory backed by small-scale lab experiments. Then a model tunnel liner was installed in a Coeur d'Alene mine--48 feet of steel pipe, 3 feet in diameter. The test pipe has four different thicknesses, and each section is instrumented with soil pressure cells, stope closure devices, and pipe deformation points. Instrumentation has been monitored for over 2 years. This field study has produced valuable time deflection data under the field loading conditions encountered.
