Abstract: Accurate detection of rock joint and fissure is the key to judge the stability of mine.The general detection steps are to extract the effective fracture information from the original image.The feature knowledge is obtained by identifying regions of interest，so as to complete the understanding of the image.The features of the mine rock fracture were summarized and analyzed firstly.Then the methods of rock fracture detection have been classified for recent 30 years，and the theoretical basis，advantages and disadvantages，research achievements based on the methods of pattern recognition，mathematical morphology and fractal theory were systematically introduced.These several methods were analyzed and compared.Finally，the present situation and development trend of rock joint and fissure detection was summarized.

Key words: Rock joint and fissure, Feature, Detection, Classification
