BANTA, Director <br />DATE: May 10, 1989 <br />T0: Matt Hayes <br />FROM: Jim Pendleton ~ - ~~~ <br />RE: Blue Rib Quart y Mine Bench Stability -March, 1989 <br />(Permit ~ C-81-047) <br />I have reviewed the April 18, 1989 quarterly stability monitoring report for <br />the Blue Ribbon mine bench, which you forwarded to my attention. The survey <br />results, collected March 22, 1989, document that the Mine Bench continues to <br />be structurally stable. While the bench has experienced another surficial <br />• slump failure, the structure is stable. <br />I recommend acceptance of the survey results as submitted. <br />cc: Sue Mowry <br />s .,t <br /> <br />215 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel.
