WIPP supplementary roof support system, Room 1, Panel 1: Geotechnical field data analysis bi-annual report
In June 1991, Waste Isolation Division (WID) initiated the design effort to develop a supplementary roof support system to extend the life of Room 1, Panel 1, to allow successful completion of the bin-scale test program. A number of potential options for ground control were considered leading to the finalization of the currently installed roof support system. This highly instrumented system is state of the art'' for mine ground control and will provide extensive geotechnical data. The system is an innovative blend of several standard techniques and incorporates five of the suggestions made by the Geotechnical Panel in its report of June 1991, on the effective life of Rooms in Panel 1. The design was subjected to an exhaustive scrutiny by two formal Design Review Panels and was approved based on reviewed design documents, on-site observations at the WIPP underground facility, and detailed discussions with members of the design team. The original requirement was to have only a section of the room completed in October in preparation for first waste receipt. This goal was met and the relatively complex installation in the entire room was completed in December 1991. The Support System, with all its instrumentation, is now fully operational and generating geotechnical data. Examination of extensometer, closure and load cell data indicate that Room support is performing within the design parameters. All the anchors were initially loaded to approximately 445 kN (1000 lbs). The results of load cell monitoring indicates a steady increase of load on the rock bolts. The anchors installed near the room centerline have shown the greatest increase with the outermost anchors showing little or no load.
