METHOD FOR THE AUTOMATED PRODUCTION OF A DEFINED FACE OPENING BY MEANS OF SLOPE-ASSISTED RADAR NAVIGATION OF THE ROLLER OF A ROLLER CUTTER LOADER

摘要

The invention relates to a method for the automated production of a defined face opening for longwall mining operations comprising a face conveyor (23), a roller cutter loader (13) as an extraction machine, and a hydraulic shield support (25) in underground coal mining, wherein the distance (22) between the top edge of the roller base body (14) and the bottom side of the slope end cap (28) of the shield support (25) below which the extraction work takes place is measured by means of at least one radar sensor (18) mounted on the roller base body (14) of the roller cutter loader (13), and said measured distance is entered into a computer as the actual value of the passage height (22) of the roller cutter loader (13) under the shield support and is then compared to a target value stored in said computer, wherein control commands for adapting the cutting height of at least one of the two cutting rollers (16a; b) of the roller cutter loader (13) are generated if a deviation is determined.
