RECLAMATION - BENCHES <br /> also be observed in the cut. The height of the cut is relatively low, not <br /> exceeding some 35' above the portals and 20' to 35' in the south cut <br /> portion. The cut slopes are on the order of 500 to 600, <br /> The storage yard cut is a very high cut reaching aheight of 100' to 200'. It <br /> has different slopes; lower cut portions are covered by rockfal -.bris that <br /> have slopes around 450. Higher cut portions are steeper, up ertical. <br /> The overall cut slope, not including rockfall debris parts, is on order of <br /> 700 to 800. The overall stability of the cut appears to be satis' )ry, but the <br /> slope is subject to severe rockfall. Some undercutting of the c 3t can be <br /> observed. No ground water seeps have been observed on the Lut face. A <br /> low angle cut is present along the east side of the storage yard. This cut <br /> has been made approximately along the bedding plane of the bedrock, <br /> which dips about 100 to the west at this location. <br /> • Several fills can be identified in the No. 1 Mine area. They include, from <br /> north to south, the fan fill, the bench fill, the "bin" fill and the storage yard fill. <br /> The fan fill is a minor fill between the mine portal and the north fan; it extends <br /> down to the haul road and farther below it (some 70'). The fill surface shows <br /> moderate rilling erosion and sloughing. <br /> • The bench fill is located in the main gully below the portal area. It appears to <br /> extend some 250' below the bench crest, although it is likely that the fill is a <br /> very shallow sliver or outwash over much of its height. This fill may be of <br /> appreciable thickness below the mine bench. Severe rilling and erosion is <br /> present on the fill surface. <br /> The bin fill provides a narrow passage across a large avalanche gully from <br /> the portal bench to the storage yard. It is very probably a thin, sliver-type fill, <br /> with an approximate maximum height of 50'. Outwash from the fill extends <br /> several hundred feet down the gully, to the confluence with the bench fill <br /> gully. Severe erosion and sloughing of this fill is causing the failure of a <br /> small timber crib wall at the narrowest portion of the fill. <br /> • The storage yard fill is again a sliver-type fill that was dumped on a very <br /> steep, natural slope (some 350). As a result, the thickness of the fill is <br /> probably limited to some 10'. The height of the fill reaches up to 500', the <br /> slope is up to 400. The fill surface is subject to severe erosion, rilling and <br /> gullying. The erosion apparently causes significant outwash from the fill; it is <br /> difficult to distinguish what parts are the fill and what is outwash from the fill. <br /> Areas of very shallow sloughing are visible on the fill surface from below the <br /> mine bench area. <br /> 9 <br />
