    Abstract: The invention is directed towards methods and compositions for treating piles of particulate materials to inhibit and prevent the loss of valuable fuel or mineral dust from being released from storage piles or open containers. The method involves applying separately to the pile two different compositions. When separate the two compositions are low viscosity and easy to spray. When combined the two form a gel coating that is resistant to erosion but is flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around. This coating is especially effective for coal piles, iron ore piles, and also for piles within and/or being moved by open topped railroad cars. The coating's flexibility prevents the coating from becoming brittle and shattering. The coating has better performance than its ingredients do alone. As a result the invention can both prevent unwanted dust pollution as well as save its users money by avoiding loss of blown away material.

    Abstract: A method for automatic watering of a zone on a worksite by a watering truck is provided. The method includes identifying a boundary of the zone on the worksite. The method further includes determining a position and heading of the watering truck on the worksite. The method further includes detecting if the position and the heading of the watering truck on the worksite is such that the watering truck is within the identified boundary of the zone. The method also includes selectively triggering one or more spray heads of the watering truck based, at least in part, on the detection.
