摘要： A method of setting an automatic level control of a plow in longwall mining operations. By means of a boom control mechanism, a control angle for setting motion of the plow, which is guided on a face conveyor, in an exploitation direction as a climbing, plunging or neutral motion is set. For each plow stroke, a cutting depth and the control angle, derived as a differential angle between inclinations of the face conveyor and of a top canopy of a shield support frame are determined. In a calculating unit, a face height change per plow stroke is calculated therefrom and a face height, as a projected height, is associated with each face position of the face conveyor. When a shield support frame that trails behind the plow in terms of a time delay reaches a respective face position, an actual height of the face is calculated and compared with the store projected height. For subsequent plow strokes, a height differential value between the projected and actual heights, determined for a respective face position, in the sense of a self-learning effect of the calculating unit when the control angle that is to be set to achieve a projected height of the face is prescribed, is taken into consideration.

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 automatically producing a defined face opening in a longwall mining operation, in underground coal mining, having a face conveyor, at least one extraction machine and hydraulic shield support frames. Inclination sensors are disposed on at least three of the four main components of each shield support frame, such as floor skid, gob shield, support connection rods and gob-side area of the top canopy. From ascertained inclination data, by comparison with base data defining a geometrical orientation of the components and a movement thereof during stepping, a respective shield height of the shield support frames perpendicular to a bed thereof is calculated. From further sensors on the extraction machine, a cutting height thereof is acquired as a face opening. In terms of a location-synchronous analysis, for possible adjustment purposes the cutting height is compared with the shield height when the shield support frame, which trails the extraction machine with a time delay, has reached the position to which relates that cutting height which was used in the comparison.

摘要： A method for automated production of a defined face opening in longwall mining operations in underground coal mining, comprising a face conveyor, disk shearer as extraction machine, and hydraulic shield support frame. At least one radar sensor is provided on a main body of the disk shearer. A distance between an upper edge of the main body and an underside of a top canopy of the shield support frame below which the main body travels during extraction work is measured, and is input into a computer as an actual value for a passage height of the disk shearer below the shield support frame. This actual value is compared with a target value and, if a deviation is determined, control commands are generated for adapting a cutting height of at least one of two cutting disks of the disk shearer.
