摘　　要：为了对复杂地质构造空间分布进行较为准确且全面地评价,提出了一种基于GPS定位、三维激光扫描、高密度电法的多源信息融合分析方法,通过对某采空区勘探得到的电阻率信息与实际物性进行相关性分析,采用形态包络和统计学方法确定电阻率临界值,累计标记法进行信息收敛并根据矿脉连续性进行图像融合,采用GPS定位标定露头洞口以及地形分布,三维激光扫描精确描述洞室空间分布状态,广域的2D高密度电法评价地下电阻率分布。综合探测结果表明除了可进入洞室外,调查区存在多个错综复杂的洞室。In order to evaluate the spatial distribution of complex geological structures accurately and comprehensively, a multi-source information fusion analysis method based on GPS positioning, three-dimensional laser scanning and high-density electrical method is proposed. Through the correlation analysis of the resistivity information obtained from the exploration of a goaf and the actual physical properties, the critical value of the resistivity is determined by the morphological envelope and statistical methods, and the information is converged by the cumulative marking method and the image is fused according to the continuity of the mineral ore. GPS, 3 D laser scanning and high-density electrical methods are used for comprehensive survey. The comprehensive exploration results show that in addition to the access to the tunnel, there are many complex caverns in the investigation area.
