Methods of and systems for dispensing dust suppressant are provided. The methods comprise forming an aqueous dispersion stream by delivering a surfactant composition to an aqueous liquid stream. The aqueous dispersion stream is mixed to form a dust suppressant. The dust suppressant is dispensed to a surface at a pressure sufficient to provide coverage of the surface. Surface tension of the dust suppressant is measured via a tensiometer, and the measurement is relayed to a controller. The forming of the aqueous dispersion stream is adjusted according to the measured surface tension relayed to the controller. The systems are configured to carry out one or more of the provided methods.

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.

The present disclosure relates to an immobilized mining microbial accelerator based on biosurfactant bacteria, including immobilized biosurfactant bacteria, immobilized mineralized bacteria, an activating solution and a cementing agent. The immobilized mining microbial accelerator based on biosurfactant bacteria is prepared by using the following steps: firstly, inoculating biosurfactant bacteria and mineralized bacteria into the activating solution to obtain a biosurfactant bacterium fermentation solution and a mineralized bacterium fermentation solution; and then, selectively adsorbing and enriching the biosurfactant bacteria and the mineralized bacteria through an immobilized material to obtain the immobilized biosurfactant bacteria and the immobilized mineralized bacteria. The hydrophobicity of the immobilized mining microbial accelerator can be improved when the microbial accelerator is applied to coal dust, and further, the improvement of the mineralization capacity and the transformation of the shape of CaCO.sub.3 crystals can be achieved through mutualism between two strains of bacteria.
