Colorado Backhoe Service Permit # M-2009-074 <br />The Orr Pit <br />GEOTECHNICAL STABILITY EXHIBIT <br />This information is presented to address the plan to mine <br />within 200 feet for one of the structures listed in Exhibit S. <br />The structure is a buried communication line on the west side of <br />County Road 33. The stable bottom of the mine in that area will <br />be approximately 4620 and the ground level along the west side of <br />the road is approximately 4610. The bottom of the excavated area <br />will be approximately 5 feet above and 60 feet east of the <br />structure. <br />As shown on the Reclamation Plan Map the floor of the mine <br />will daylight out on the west side the mine leaving a level area <br />at the same elevation as the road. There will be no excavation <br />below the road elevation and therefor no excavated slope to fail <br />along that side. In other words there is no slope to fail that <br />could damage the phone line. See sketch below for pictorial <br />representation of this discussion. <br />46 ft <br />?N <br />a <br />4610' 0 B Ft (ESTMATED)
