基于三维建模技术的矿山移动范围圈定

Determination of Mine Movement Scope Based on 3D Modeling Technology

结合罗山矿区工程实例,提出了一种将传统的工程类比法或数值模拟方法与矿山三维建模技术相结合来确定金属矿山移动范围的方法。介绍了以MAPG IS、AutoCAD及SURPAC软件为主要工具的矿山三维建模的基本原理和步骤。在移动范围确定过程中,借助先进的3D建模技术获得三维矿山模型。该模型可以实现各类地质体的可视化,直观地展示其形态与产状,清晰地反映各构成因素间的相互关系。在3D模型中截取的特征剖面与工程类比法或数值模拟方法相结合,能轻松获得各特征剖面上的岩移参数值。通过给定的岩移参数值进而确定各特征剖面上的地表移动边界点,将各移动边界点连接即可实现矿山移动范围的圈定。

Based on the practical engineering project in Luoshan Mine, a new determination method for metal mine movement scope was proposed with the traditional engineering analogy method or numerical simulation method combined with 3D modeling technology. In the course of determination of movement scope, a 3D model of mine was obtained with advanced 3D modeling technology, which can make the whole geological structure and all kinds of geological components visualized with the interrelationship among each component clearly represented on computer. The combination of the characteristic section obtained from the 3D model with the engineering analogy method or numerical simulation method can easily provide the rock movement parameter on the section. And the boundary point of surface in the characteristic section is obtained, so the mine movement scope can be determined easily by connecting each boundary point.
