<p>Apparatus and method used for either partially or totally covering stockpiled material (100). The stockpiled material (100) may optionally be stored in a conical pit (101) and is covered by the apparatus (106) which consists of a conical framework with radial spars (111) covered with a sheet-like material. The apparatus is supported on the ground or by an embankment (104) and preferably has a discharge auger (111) which discharges material to be stockpiled through opening (110) in the top of the apparatus (106). The conical pit may also have a reclaim auger (103) for removing stockpiled material to a recovery location. Inside the conical pit (101) the reclaim auger (103) is normally protected inside a metal pipe (105). The apparatus may also extend over the crest (107) of the embankment (104) to prevent ingress of water.</p> |
