    摘要: Method of automatically producing a defined face opening, in underground coal mining, during longwall mining operations having a face conveyor, a disk shearer loader and a hydraulic shield support. Via at least one inclination sensor on the top canopy of the shield support frame, the inclination of the top canopy relative to the horizontal, in the direction of mining or extraction of the disk shearer loader, is determined to provide angles of the course of an overlying stratum at the shield support frame. A stepping path length of each shield support frame is detected, and therefrom a cutting depth of the disk shearer loader during an extraction run is determined. A cutting height of the disk shearer loader is detected by means of sensors disposed thereon, and a cutting height of the disk shearer loader is adjusted in alignment with the angle of the course of the overlying stratum to produce the defined face opening.

    摘要: A method for maintaining, in a controlled manner, a top canopy/coal-face distance expedient for rock mechanics, in longwall mining operations in underground coal mining, using a face conveyor, at least one extraction machine, and a hydraulic shield support frame. Inclination sensors are disposed on at least three of the four main components of the shield support frame, including floor skid, gob shield, support connection rods and gob-side area of the top canopy. An inclination of the top canopy and floor skid are ascertained via the sensors. From the ascertained inclination data, in a computer, the effects on a top canopy/coal face distance are determined when changes in an angle of inclination of the top canopy occur. An automatic adjustment of decisive cycle parameters of the shield support frame are carried out, wherein the work cycle comprises retraction, advancement and setting processes.

    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 retractable prop at the working face end to the working face, and of a canopy, which is 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 portion pivotal on the floor skid, and an upper portion which is rigidly connected to the canopy at the opposite end of the canopy from the working face end. The shield is connectable to an extensible and retractable prop and a lemniscate guidance mechanism, so that the upper part of the shield may be moved upwardly and downwardly along its longitudinal axis. The upper part also carries an opening for the passage of a blast pipe which is supported on roller means carried by the canopy.

    摘要: A longwall mining system includes at least one face end roof support having a longitudinal length, and at least one near end roof support adjacent the face end roof support. The near end roof support has a longitudinal length substantially shorter than the face end roof support longitudinal length. There is also at least one face roof support adjacent the near end roof support, and the face roof support has a longitudinal length substantially shorter than the near end roof support longitudinal length. There is also a forward conveyor extending forward to and attached to the face end roof support, the at least one near end roof support, and the at least one face roof support, and a rearward conveyor extending rearward of and attached to the face end roof support, the at least one near end roof support, and the at least one face roof support. This creates an effective cave line at an angle to the coal face, that helps reduce the goaf pressure on the face end, thereby increasing the stability of the main gate roof support.
