| 20110006584 | Method for Automatically Producing a Defined Face Opening in Plow Operations in Coal Mining - A method for automatically producing a defined face opening in a longwall mining operation in underground coal mining, using a face conveyor, at least one plow, as an extraction machine, guided on the face conveyor, and respective hydraulic shield support frames having, as main components, a floor skid arrangement, a gob shield, a top canopy and support connection rods. Inclination sensors are disposed on at least three of the floor skid arrangements, the gob shield, the support connection rods and a gob-side region of the top canopy. From the sensors, an inclination relative to a horizontal is ascertained. From the inclination data, by comparison with base data defining a geometrical orientation of the components and movement thereof during a stepping process, a respective shield height of the shield support frames perpendicular to a bed thereof is calculated and is compared with a machine-dependent fixed cutting height of the plow to establish if deviations exist: By means of a boom controller disposed between the shield support frame and the face conveyor, a height control of the plow is initiated to correct established deviations and is maintained, in the sense of a location-synchronized evaluation, until the shield support frame, which trails the plow with a time delay, has reached the position at which the plow was located at the point in time when the height control of the plow was initiated. | 01-13-2011 |

| 20120161493 | Method for Producing a Face Opening Using Automated Systems - 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. | 06-28-2012 |
