摘要： A method for controlling a longwall mining operation, including a face conveyor, at least one extraction machine, and a hydraulic shield support, in underground coal mining. Using inclination sensors 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 region of the top canopy, the inclination of the shield components relative to horizontal is ascertained in the direction of step. In a computer, the ascertained inclination data is compared with base data stored in the computer that defines the geometrical orientation of the components and their movement during stepping. From the comparison, a respective height of the shield support frame, at the forward end of the top canopy, is calculated as a measure for the face opening.

摘要： 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.

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.
