摘要:
目前,深部矿已成为我国矿产勘查的重要对象.由于深部矿具有埋深大、矿化信息弱、综合地质研究程度低的特点,使传统地球物理探测技术应用的有效性受到较大影响,造成深部矿勘查的难度加大.金属矿地震探测技术是一种有潜力的新方法技术,具有探测深度大、探测精度高等特点,将该方法技术应用于新疆喀拉通克铜镍矿区深部找矿,把压制干扰噪声作为数据采集和资料处理的重点,采用强能量震源激发、小道间距、高覆盖次数的观测系统,细化叠前去噪数据处理流程,取得了较好的探测效果,部分成果得到钻孔验证.
Abstract:
Currently,deep mineralization has become an important object of mineral exploration.The deep mineralization is characterized by deep burial depth,weak mineralization and a low level of synthetic geological study.Such a situation influences to some extent the application of geophysical technology,and causes more difficulties in the exploration of deep mineral deposits.Seismic method for metallic ore exploration is a new and promising technique,which has such merits as great detecting depth and high detection accuracy.This exploration technology was applied to deep prospecting in the Kalatongke Cu-Ni deposit of Xinjiang,with the emphasis placed on the suppression of the background noise in data acquisition and processing.During the field seismic exploration,the acquisition method included such means as a large explosive excitation,a small detector spacing and higher stacking fold.The technique achieved good detection results,with some of the results verified by drilling.
