Abstract: The use of imaging geological record technology can improve the efficiency of the mine geological record. The traditional geological record means are ineffective, these can not quickly identify the geological structure and which affect the progress of mine production. Besides, it is more difficult to preserve the results of geological record. Based on the technology of close-range photogrammetry, the article describes the basic situation of geological record instrument, and introduces processes of geological record instrument and shows achievement. Compared with traditional methods, geological record instrument can accurately, detailed, timely catalog geological changes in mining and provide favorable geological guarantee.
