金属矿地震勘查方法评述

经过几十年的发展,金属矿地震勘查方法形成了以2D、3D、VSP方法为主的地震反射系列,提出了地震散射法,并取得了一定的试验效果.金属矿地震找矿的应用范围得到了扩展,不再局限于矿体本身,控矿构造、蚀变晕、重要岩性层等大型深部构造单元成为了地震间接找矿的目标体.目前,金属矿地震勘查方法,尤其是3D、VSP方法,面临着成本高、技术难度较大等问题,应进一步加强基础理论和解释方法研究,建立金属矿地震技术示范区,为推广和应用金属矿地震方法开拓思路、积累经验.

Review on Seismic Methods for Mineral Exploration

After dozens of years of development, seismic methods for mineral exploration have been dominated by seismic reflection series, such as 2D, 3D, VSP methods. Seismic scattering has been put forward and some test results have been achieved. Seismic methods for mineral exploration have been applied into more fields than just ore body itself, and the large deep-seated structures, such as ore-controlling structure, alteration zone, and key lithologic layer have become the targets of indirect seismic exploration. At present, seismic mineral exploration methods, especially 3D and VSP, face a few problems, such as high costs and technique difficulties. In order to make the seismic methods for mineral exploration popularizing and applicable, studies of basic theory and interpretation should be strengthened further, and some demonstration areas for seismic mineral exploration should be set up for accumulating more experience and stimulating thoughts.
