Abstract

Disclosed is a method for automatically creating a defined face opening in longwall coal mining operations comprising a face conveyor (20), at least one extraction machine (22), and a hydraulic shield support. In said method, the inclination of the shield components relative to the horizontal line is determined by means of inclination sensors (17) mounted on at least three of the four main components of the shield support frame (10), the shield height (31) of the shield support frame (10) perpendicular to the bed is calculated in a computer unit, and the cutting height (32) of the extraction machine (22) is detected as the face opening, the cutting height (32) of the extraction machine (22) being adjusted to the shield height (31) of the shield support frame (10) by means of a locally synchronous evaluation.
