Abstract
Provided is a dust scatter preventing agent capable of preventing scattering of dust for a long period of time, by improving the strength of a coating layer formed on a surface of a tailing at a tailing accumulation site. A dust scatter preventing agent comprising an aqueous solution or aqueous dispersion that includes a hydrophilic polymer such as polyvinyl alcohol or a synthetic resin emulsion that has a property of being solidified and that has a contact angle with water of 45 degrees to 78 degrees, and an insoluble fiber material such as vinylon that has a cut length that is within a range of 0.5 mm to 30 mm, and a fineness that is within a range of 0.1 dtex to 20 dtex, with an amount of the insoluble fiber material with respect to the hydrophilic polymer being 0.1 to 1 by mass ratio, is spread over a surface of an object that includes fine particles having a particle size of 100 μm or less and hardened to form a coating layer on the surface of the object.
