    Abstract: 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.

    Abstract: A cutting pick includes an elongate shank, a cutting tip fixed to one end of the shank to project from that end and which is of a material that is harder than the material of the shank, and an annular sleeve which is attached about the shank adjacent the cutting tip. The sleeve is of a material (e.g., tungsten carbide) which is harder than the material of the shank and which has a lower propensity for incendive spark production during a cutting operation than the material of the shank. The sleeve includes a plurality of annular sleeve portions which are attached about the shank immediately adjacent to each other.

    Abstract: Sprayable, pre-mixed, mine sealant compositions having enhanced strength properties and capable of retarding flame propagation and suppressing combustibility of substrate materials are disclosed in three general forms. In the first form, an alkaline silicate material such as sodium silicate is employed with perlite and a mineral acid in order to provide the above properties. In a second formulation, the first form is augmented by white pigments. In a third formulation, additional bulking materials e.g., cellulose are added to provide enhanced structural integrity and mine sealant qualities.

    Abstract: The cutting head (1) has passages (14, 16; 22) extending through the cutting head in axial direction thereof and being connected with the axial water supply bore (8) by radial bores (9). Radial bores leading to the outlet nozzles open into the passages (14, 16; 22) extending through the cutting head in axial direction thereof. The passages (14, 16; 22) extending through the cutting head in axial direction thereof can be closed at at least one side by means of detachable closure members (15), so that these passages (14, 16; 22) extending through the cutting head in axial direction thereof can, after having removed the closure members, be cleaned by means of a cleaning-rod.

    Abstract: In suppressing coal dust by the application of a foam to a falling mass of coal, a continued dust suppression effect is achieved by foaming a water-diluted emulsion of water, a surfactant, and an oil which exhibits a tacky characteristic when in the form of a film in the absence of water at temperatures within the range from approximately 21.degree. C. down to approximately -12.degree. C.

    Abstract: A device for closing off a mine gallery, especially for use to prevent spreading of underground explosions, in which a bag of flexible substantially airtight material is first inflated with a gas under pressure, for instance air, until the inflated bag engages with its peripheral surface the inner face of the mine gallery, whereafter a flowable material is pumped into the interior of the bag, displacing the gas under pressure, which is permitted to escape through at least one overpressure valve provided in an uppermost portion of the inflatable bag. The material to be pumped into the interior of the bag is of a nature which quickly hardens after being pumped into the bag to thus provide a solid barrier extending across the mine gallery.
