煤田三维地震勘探技术的应用及发展前景
|
摘要
以典型实例说明三维地震勘探技术在矿井开采中的应用。随着数字地震仪和数字处理解释技术的广泛应用,利用3D、3C和全波三维地震勘探技术将拓宽在岩性参数方面的研究,可以利用纵、横波速度比、传播时间比、振幅比、泊松比等来研究岩石孔隙度的变化等,也可以利用横波分裂现象研究介质的各向异性,提高勘探精度,提供接近实际地层的岩性参数。并逐步地实现地表面以下的信息数字化,为矿井高产、高效提供可靠的地质保障。
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.
