PROBLEM TO BE SOLVED: To provide a dusting suppression method for a coal pile in which the increase of cost is suppressed, and dusting can be effectively suppressed.SOLUTION: Provided is a dusting generation method for coal, comprising a step of contacting the fine grains of the coal with water; and a step of mixing the fine grains and the other grains of the coal. It is preferable that the coal is made of modified coal obtained from porous coal. It is preferable that the grain size of the fine grains is 500 μm or lower. The mass ratio between the fine grains and the other fine grains in the mixing step is (1:99) to (1:3). |
