摘要自改革开放以来，中国煤矿工业不断发展，煤炭已经成为国民经济的重要组 成部分。传统的煤层信息获取方式，主要是依靠工程技术人员对煤层平面图的分 析和判定，由于地下煤层分布较为复杂，煤层平面图较为抽象，所以在煤层信息 的获取过程中，会存在技术人员的误判，从而造成煤炭资源的浪费和企业经济的 损失。
煤层的三维显示可直观的表现出煤层的空间状态和赋存状况，可以让人直 接、完整、准确地理解和感受地下煤层的构造情况，能够满足工程技术人员对煤 层空间分析的需求，对煤炭资源的可持续利用也有着深远意义。本论文将探讨采 用克里金插值三维建模的方法，通过已有的 CAD 煤层底板等高线图，利用克里 金法插值出煤层顶底板等高面，并在 GIS 中实现煤层的三维显示。最后可以发 现，克里金插值三维建模的方法可以较真实的反映出煤层的实际分布状况，拟合 程度较好。69365

Underground Coal Seam 3D Display
Abstract
Since the reform and opening up, China's coal mining industry has developed a lot, coal has become an important part of the national economy.Traditional way of information acquisition of coal seam, mainly rely on the coal seam floor plan analysis and judgment of engineering and technical personnel. Because of the complex of distribution of underground coal, coal seam floor plan is more abstract, there will be a misjudgment of the technical staff in the process of acquiring the information of coal seam, thus resulting in the waste of coal resources and corporate economic losses.
Three-dimensional display of coal seam can make people directly, completely and accurately understand and feel the underground coal seam structure which can intuitively show the space state and coal seam occurrence condition, but also let engineering and technical personnel meet the needs for spatial analysis of coal seam and it has far-reaching significance to the sustainable use of coal resources. This paper will explore the use of Kriging interpolation method of 3D modeling, through the existing CAD coal floor contour map by Kriging interpolation out of the coal seam roof and floor,and to achieve a three-dimensional display seam in GIS . Finally, can find Kriging interpolation method for 3D modeling may be more realistic to reflect the actual distribution of the coal seam,the fitting degree is better.
