• PROJECT: FLOW FROM GLOBE HILL MINE TO SCHIST ISLAND MINE - MOD DATE: 11/19/2008 <br />AUTHOR: Adrian Brown, P.E. PAGE: 1 OF 4 <br />OBJECTIVE <br />To determine the maximum possible flow from the Globe Hill mine to the edge of the permit <br />boundary due to precipitation. <br />CONCEPT <br />1. Precipitation causes buildup of water in the base of the Globe Hill Mine. <br />2. Flow occurrs laterally through the rock separating the Globe Hill from the backfilled Schist Island Mine. <br />3. Flow occurs laterally through the Schist Island backfill (assumed saturated to lip) <br />4. Concurrently, vertical flow occurs in bedrock and the backfill because diatreme is drained to Carlton Level. <br />A, 'I <br />4JS <br />PLAN % <br />North <br /> 10500 - SECTION A-A' _ <br /> Schist Globe <br /> Island Mine Hill <br /> 10000 (backfilled) Mine <br /> Horizontal Flow from GH to SI <br /> <br /> 9500 <br /> 9000 ? ? ? ?
