摘要
煤炭作为我国主要的能源来源,其勘探与开发对国家能源安全和经济发展具有重大意义,针对煤炭勘探区域地质条件复杂,特别是断层的存在对三维建模带来的挑战,采用了一套科学的煤炭勘探三维建模方法.该方法包括数据预处理、边界环构建、复杂断层处理、曲面构建与优化等步骤.首先,通过数据预处理确保数据的兼容性和完整性;其次,构建边界环为三角剖分奠定基础;再次,针对复杂断层采用精细的处理策略;最后,采用Delaunay三角剖分算法构建并优化三维曲面.通过实例验证,提出的方法能够有效解决复杂断层处理难题,提高三维地质模型的准确性和实用性.研究结果表明:该技术在实际应用中取得了显著成效,不仅为煤炭勘探提供了精确的地质信息支持,还促进了煤炭资源的可持续开发,对推动我国煤炭勘探技术的进步和煤炭工业的持续健康发展具有重要意义.
Abstract
Coal,as a main energy source in our country,plays a significant role in the national energy security and economic development.Given the complex geological conditions in coal exploration areas,especially the challenges posed by fault zones to three-dimensional modeling,a scientific method for coal exploration 3D modeling has been adopted.This method includes data preprocessing,boundary ring construction,fault zone handling,and surface construction and optimization.First,data preprocessing ensures the compatibility and integrity of the data.Second,boundary rings are constructed to lay the foundation for triangulation.Then,fine-tuned strategies are applied to handle the complex fault zones.Finally,the Delaunay triangulation algorithm is used to construct and optimize the 3D surface.Through case studies,it is demonstrated that the proposed method effectively addresses the challenges of fault zone handling and improves the accuracy and practicality of 3D geological models.The research results show that this technology has achieved significant success in practical applications,provides precise geological information support for coal exploration and promotes the sustainable development of coal resources.It also plays a key role in advancing coal exploration technology and the sustained healthy development of the coal industry in our country.
