基于集合论集成的复杂煤层建模

Complicated coal seam 3D modeling based on set theory

为了解决复杂煤层空间建模困难问题,在深入分析复杂煤层建模机制基础上,采用集合论集成的方法和思想,研究了煤层建模方法。结果表明:通过采用集合论集成的数据模型可将空间地质体分为五大部分,九种相应的数据结构类型,同时设计并研发出地质体建模模拟系统。通过断层和巷道为例进行验证,得出该建模方法实用可行,并能够有效提高建模速度和精度的结论。该结果对地质体建模具有一定参考价值和借鉴作用。

In order to model complicated coal seams,a new modeling method is developed based on the composite set theory.Spatial entities are decomposed into five fundamental data types and nine data structures.Also,based on the decompositions,the modeling and simulation system for spatial entity is developed.A case study on fault and mining roadway shows that the data model based on the composite set theory can improve the speed and accuracy of modeling process.The study results provide a useful tool for modeling geological body.
