Exemplified by typical practical cases, this paper has explained the application of three-dimensional seismic exploration technology to the mining work. With the widespread application of digital seismograph and digital processing and integration technique, the utilization of 3D3C and full wave three-dimensional exploration technology will broaden the study scope of rock character parameters. The velocity ratio, propagation time ratio, amplitude ratio and Poisson's ratio between the longitudinal wave and the transverse wave can be used to study the variation of rock porosity. The splitting phenomena of the transverse wave can also be utilized to study the anisotropy of media. With these means, the exploration precision can be improved and the rock character parameters close to practical conditions of the strata can be provided. In addition, digitalization of underground information can be gradually realized so as to provide reliable geological basis for high-efficiency production in the mining shaft.
