虚拟矿山系统中三维断层模拟技术

Technique for 3D fault simulation in virtual mine system

由于断层空间展布的复杂性及断层数据的缺乏。根据断层的基本属性,运用单一平面或者多个平面拟合断层面的方式,推演未知断点,对断层的空间几何形态进行数学描述;并且提出了基于体分割的层次三维拓扑结构和基于面向对象的框架模型。实例表明,所提出的方法能够有效而准确地实现包含正、逆断层以及尖灭断层等复杂断层的三维模拟。

Modeling faults in 3D in virtual mine system is the most important and most difficult techniques. An approach is presented to implement mathematical description for the geometry of the faults in spatial distribution. It only depends on the basic properties of geological faults in the coal mining region. In addition, to build the relationship among the geometric objects, a 3D multi-levels topology based on the partition principle is described, and an object-oriented framework is introduced. Test results show that the proposed scheme can accurately describe 3D complicated faults involving obverse faults, reverse faults and faults that terminate within geologic models.
