A method for storing a modified coal includes a pile forming step of forming a pile by stacking a blended coal of an agglomerate-shaped coal and a powdery modified coal. The modified coal has a content of particles having a particle diameter of 2 mm or less of 35% by mass or more. The pile formed in the pile forming step has a packing density of 1.0 g/cm.sup.3 or more.

A cover-after grain tarp is disclosed. The cover-after grain tarp includes, for example, a tarp body having a plurality of tarp sections joined together at one or more seams, each tarp section comprising a plurality of tarp panels having an outer terminal edge spaced between opposing converging edges and an edge panel secured along its length to an adjoining one of the plurality of tarp panels. The edge panel is configured for securing to hardware of a center tower structure at a grain storage location.

The invention provides a management system of coal and/or steelmaking dust being managed outdoors. The management system includes an imaging unit, a threshold information acquiring unit, and a determining unit. The imaging unit is configured to perform imaging of heat distribution image information indicating a heat distribution image of a surface layer of a pile of the coal and/or steelmaking dust from a position where imaging of an entire surface layer of the pile can be performed. The threshold information acquiring unit is configured to acquire threshold information indicating a threshold of a temperature of the surface layer of the pile. The determining unit is configured to determine heat generation of the pile based on the heat distribution image information and the threshold information.
