The remaining walls are also considered to be currently stable, though the present <br />analysis for the west wall and both the southwest and southeast walls each indicate the <br />possibility for wedge failures, and possibly planar failures, to occur. These two walls of the <br />quarry should continue to be monitored closely as mining continues. As documented in <br />the past, localized raveling, especially along the south walls is likely to continue. <br />Continuation of the safety-minded policies already in place, which limit the height of the <br />exposed highwall, as well as the reclamation of exposed highwalls as soon as possible <br />following blasting and rock haulage, will aid in minimizing the potential for instabilities to <br />occur. <br />- 21 n Lachet & Associates <br />4 SC11NAOft fP'G 1!:f F.RING CONPANY
