矿区复杂地质构造隐式三维集成建模
Implicit 3D Integrated Modeling of Complex Geological Structures in Mining Areas
【摘要】 隐式建模方法具有建模过程自动化的优势,并成功应用于浅表地质构造自动建模.然而,对于含侵入岩、断层、采空区等多种深部复杂地质构造的矿山区域,自动集成建模方法仍存在困难.本文基于HRBF(Hermite radial basis function)隐式建模方法,针对矿区煤层、侵入岩、采空区、断层等构造分别提出了隐式建模特征向量提取方法,并设计了构造模型与地层模型的隐式集成方法,实现了煤矿区域复杂地质构造的拓扑一致集成建模.济南市地铁8号线区域的实际案例研究表明,该方法能够实现侵入岩、采空区以及断层的隐式建模,为城市轨道交通工程建设提供了辅助决策与安全保障.
【Abstract】 The implicit modeling method offers the advantage of automating the modeling process and has been successfully applied to automatic modeling of shallow geological formations. However, the automatic integrated modeling remains challenging for mine areas with multiple deep and complex geological formations such as intrusive rocks, faults and goaf. Based on the HRBF implicit modeling method, this paper proposes the implicit modeling feature vector extraction method for the coal seam, intrusive rocks, goaf, faults and other structures in the mining area, and designs the implicit integration method between the structural model and the strata model, enabling the topology-consistent integrated modeling of complex geological formations in the coal mine area. A case study of Jinan Subway Line 8 shows that this method can realize the implicit modeling of intrusive rocks, gobs and faults, which provides auxiliary support for decision-making and ensures safety in the construction of urban rail transit projects.
