Hence, location recognition and edge detection of coal gangue with high accuracy is vital to intelligent longwall top coal caving (LTCC) mining. Aiming at the random distribution of different coal gangue types in fully mechanized caving face under the visible lens, a new method of gangue mixed ratio recognition by marker matching method was proposed. The locations of the motion-blurred images of coal and gangue were carried out, and an automatic recognition system of coal and gangue was developed based on the fusion features of grayscale and texture. The experimental results show that when the speed is in the range of 0.2 ~ 1.0m/s, the recognition accuracy of the coal and gangue type with small gray difference is more than 92%, and the recognition accuracy for the coal and gangue types with large gray difference is more than 97%. Furthermore, based on the improved HSV color space model of RGB, the morphological segmentation of the coal and gangue blocks are effectively carried out by using the mean binarization method.
