I; <br />I' <br />1 <br />II. <br />j' <br />i <br />1 <br />1 ~i <br />r <br />~; <br />u <br />li <br />1 <br />I. <br />' I <br />i <br />1 <br />1 <br />i <br />II <br />- 2 0 - <br />We expect that the foundations of the conveyor will have <br />to reach sound and intact bedrock; the depth to it is not known, <br />but it may reach several tens of .feet. Piles or drilled piers <br />may comprise the best foundation method for the conveyor. <br />We also believe that apart from this foundation method, it <br />will be necessary to stabilize a strip of soils along the <br />conveyor to prevent any deformations or slides of surficial <br />soils. The stabilization could probably be achieved with a <br />drainage system which would effectively lower the ground water <br />surface below the soil-rock contact. A detailed foundation in- <br />vestigation which includes drilling at the locations of indi- <br />vidual conveyor supports will be required prior to the conveyor <br />design. <br />A re_fus_e_pile (or waste rock storage) has been tentatively <br />planned on a large and flat bench immediately south of the <br />landslide area (elevation about 6,640 feet and higher). The north <br />border of the pile would be located close to the distinct crest <br />which forms the boundary between the landslide area and the bench <br />above it. <br />We are concerned with the stability of the area close to <br />this crest; it is very probable that landslides in the Mount <br />Gunnison area have been developing as failures of bench crests <br />of this type. Any loading of the area above the crests increases <br />the risk of a new failure. <br />For this reason, we feel that it is important to avoid load- <br />ing of the bench part close to this crest. As there are no data <br />available on subsurface conditions of this part of the property, <br />it is difficult to specify a safe distance of the refuse pile toe <br />from the crest. We feel that for preliminary purposes a distance <br />of 150 feet is appropriate; it is based on morphologic obser- <br />ao«.uo cowun+a.~c <br />
