摘要： The assembly has a supporting structure for high pressure hydraulic nozzles, the supporting structure including a single shield-like structural member, having a channel cross-section open toward the working face, and which is rigid against bending and extends, parallel to the working face, between two roadways. Winch drag means extend along the two roadways and act on respective opposite end portions of the structural member to move the latter in the direction of advance of the workings. High pressure nozzles are mounted on the flange edge portions of the supporting structure projecting toward the working face, being positioned at fixed locations and being adjustable perpendicularly to their discharge axes. Alternatively, a carrier mounting the high pressure nozzles is movable longitudinally of the supporting structure to travel parallel to and along the entire length of the working face. The supporting structure is inclined in the backward direction, toward the old works, for permitting the caving-in roof to slide down toward the old works. The supporting structure also is divided longitudinally into a roof portion and a base portion, the two portions being adjustable relative to each other. Conveyors extending along the roadways receive the dislodged portions of the mineral deposit, such as coal, and convey the same to a collecting area. The supporting structure furthermore may be designed as a conveying trough discharging into the conveyors.

摘要： A device for reducing dust in workings such as underground workings which are supported by shields comprises a plurality of shields each having a top and a side wall on at least one side disposed alongside and spaced from the next adjacent shield side wall. A liquid conduit is carried by the sheild adjacent the top of its side wall and it is provided with a plurality of openings or discharge nozzles along its length in order to direct a dust settling liquid or spray downwardly adjacent the side wall. An elastic seal extends outwardly from the bottom of the side wall and applies against a similar seal of the next adjacent shield. The two shields together define a runoff gutter for the liquid employed to settle the dust.

摘要： An advancing support system which is adapted to follow the dip of a longwall in an underground mine operation, comprises an abutment made up of a plurality of individual beams which are arranged in end-to-end axial alignment along the length of the longwall, and which are pivotally connected together in a manner so that they may pivot substantially only in one plane, perpendicular to the footwall. A support unit is associated with each individual beam, and each support unit carries a piston and cylinder combination connected to the individual beam, for shifting the beam relative to the longwall.
