基于块段模型的复杂地质体三维数值模拟技术

Technology of the Three-dimensional Numerical Simulation with Complex Geological Model Based on the Block Model

针对多介质复杂条件下的岩体工程,利用建立在块段模型建模技术之上的Micromine矿业软件建立了完全反映地质结构及岩性在空间上分布情况的精确三维地质模型,再利用三维地学模拟与数值模拟的耦合集成技术,建立既"可信"又"可算"的力学模型,实现了FLAC3D三维数值模拟软件建模的直观、快速和自动化。通过铜陵冬瓜山矿三维回采方案的建模实例检验了该方法的有效性和可行性。

Aiming at some rock project under complicated multi-medium condition, an accurate three-dimensional geological model was set up by using Micromine based on the block modeling technology, which can completely reflect the spatial distribution of geological structure and rock properties. Then with the coupling and integrating technology of three dimensional geoscience simulation and numerical simulation, a ＂reliable＂ and ＂calculable＂ mechanical model was set up, realizing intuitive, fast and automatic modeling by FLAC three-dimensional numerical simulation software. The effectiveness and the feasibility of the method were tested in the practice of modeling of 3-dimensional stoping program in Tongling Dongguashan mine.
