摘要： This disclosure describes formulations and methods for dust control, for example, coal topping, a term which refers to the application of liquid products to the top of coal loads, such as those in open topped coal hopper railcars as commonly used today to transport coal. Disclosed herein are wax-based emulsion formulations that accomplish dust control during industrial operations in which dust handling is required.

摘要： A canopy and shield structure for supporting a shield adjacent a working face in a seam-like mine deposit, comprises a floor skid which is connected through an extensible and contractable prop at the working face end to the working face end of a canopy adapted to be positioned in parallel relation to the roof strata. The working space is covered at the waste removal end by a shield which includes a lower two-arm lever portion which is pivotally mounted on the skid and an upper portion which is pivotally connected to the longer arm of the two-arm lever adjacent the upper end thereof and is also pivotally connected to the canopy. The two-arm lever is driven by a hydraulic drive motor and a parallel linkage is connected between the upper shield part and the canopy in order to provide a guidance of the canopy in a direction substantially perpendicular to the strata. The upper part of the shield also includes an opening for the passage of a blast pipe and the canopy advantageously includes a guideway for supporting the blast pipe for shifting movement toward and away from the working face.

摘要： 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.

摘要： A quick connect system for the assembly of underground mining dust and fire suppression systems can eliminate the need for threading pipe with couplings during the installation, reducing installation times approximately 75%. The quick connect system results in the quick and easy coupling and positioning of sprays along the water line. The quick connect system typically uses galvanized, brass and stainless steel components to reduce the need for replacement and to provide for quick adjustment of fittings with sprays using pliers. The system is simple to maintain and reduces high installation and maintenance labor costs. The system uses male and female ported fittings and horseshoe pins. Pendant style or deluge style sprays can be used in the system and can be pre-installed prior to delivery and installation of the system.
