The invention relates to a method for controlling a cutting extraction machine, which can be moved along a working front in longwall mining, in which method the heat emission of the working face (4) newly exposed by the extraction machine, in each instance, is observed using an infrared camera (10), and control data for the subsequent extraction run are generated on the basis of this observation. In order to make this method problem-free and more useful for practical situations, the invention proposes that observation of the heat radiation takes place perpendicular to the working face (4) and at a minimum distance from the cutting tools of the extraction machine, that a key bed package (X) having a characteristic sequence of border surfaces between layers of different heat conductivity is determined, that at the end of each extraction run, the progression of this key bed package (X) is determined, with reference to the delimitation surfaces of the longwall, on the basis of the heat images, and that the control data for the next extraction run of the extraction machine are generated on the basis of this progression of the key bed package. |
