Abstract
The present invention is directed to an improvement in dust control methods used at strip mines. The invention is based upon super absorbent polymer used in combination with water. The polymer is premixed with water and is applied to the roads by use of a conventional truck capable of dispensing water. The super absorbent polymer provides water retention and can be re-hydrated by rain, dew, or additional tanker water. The method disclosed includes the step of: adding about 15 gallons of dry super absorbent water swellable polymer to each 2000 gallons of water placed within the water tanker, stirring the polymer into the water to form a mixture, and distributing the mixture over strip mining roads.
