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 within 200 feet for one of the <br />structures listed in Exhibit S. The stricture is a buried communication line on the west side of <br />County Road 3 1. The stable bottom of the mine in that area will be approximately 4620 and the <br />ground level along the west side of the road is approximately 4610. The bottom of the excavated <br />area will be approximately 5 feet above and 60 feet east of the structure. <br />As shown on the Reclamation Plan Map the floor of the mine will daylight out on the west <br />side the mine leaving a level area at the same elevation as the road. There will be no excavation <br />below the road elevation and therefor no excavated slope to fail along that side. In other words <br />there is no slope to fail that could damage the phone line. See sketch below for pictorial <br />representation of this discussion. <br />\ol <br />a Q <br />46 f t. <br />4610' <br />8 f t (ESTIMATED}
