4100-3250 Tunnels Hydraulic Communication Test, Emergency Response and Notification Plans

Microform - 2004

A key factor in the proposed water treatment plant at the abandoned Britannia Mine in British Columbia is the need to utilize the underground workings as a water storage reservoir. The storage configuration includes the 4100 tunnel, which is plugged, and a shaft connecting the tunnel upward to the 3250 tunnel, which opens to the surface. A test is to be carried out at the mine site to verify the hydraulic conductivity between the 4100 tunnel and the 3250 portal, as part of an evaluation of the use of the 3250 tunnel as a reservoir outflow. This report describes an emergency response & notification plan for the test. It includes a description of the tunnels & adjacent areas at the surface, the mine drainage system, contingency plans for alternate drainage, the valve arrangement at the 4100 tunnel plug, the emergency resources & equipment available, the location & access of the 3250 portal, and emergency procedures in case evacuation of the area downstream of the mine reservoir becomes necessary during or after the test.
