An Orientation Method Fit for the Photogrammetry of the Excavating Face in a Coal Mine

Abstract:

Geological logging is a fundamental technical practice in a coal mine and also one of the most important technical jobs for the production of the coal mine, having important significance for the coal mine’s safe production and source recycling. Irregular shapes of the excavating faces make current photographic geological logging mode and methods unfeasible, so this paper studies critical techniques and methods of underground excavating face photographic geological logging in coal mines and proposes a new close-range photogrammetry control method, orienting the excavating face’s stereoscopic image using the directing laser and the plumb line, and proves through experiments that the positional accuracy of this method meets the requirement of the geological logging and that this photogrammetry orientation method is suitable for geological logging of the roadway excavating face images of coal mines.
