| 英文摘要 | It is the key problems to detect the small structure, abnormal body and the coal thickness changes in the development of underground coal mining, and channel wave detecting provides important geophysical exploration methods to solve those problems. Transmission measurement was carried out on 11061 working face mining in Yima Mine. Thickness of coal seam from roadway changes from 1.5 m to 8 m, so it is not suitable for travel-time tomography. From theoretical dispersion curve analysis of velocity and thickness relations, we chose 125 Hz frequency channel wave to image about 2 m to 5 m thickness of coal seam thickness. Calculating the 684 dispersion curves and picking up the group velocity and travel-time at 125 Hz of channel waves respectively, we obtain the distribution of velocity, thickness distribution and stress within working face, and the result is verified by mining. |
