为表达复杂的煤矿地质构造形态,更准确地反映地质构造要素之间的空间关系,对煤矿三维地质建模及可视化应用进行了研究.按断层分块建模,用断层模型修正块段边界并合成完整的煤矿地质体模型,最终建立基于面模型的多层三维地质模型.在此基础上,应用OpenGL技术建立了实际应用的系统.应用结果表明,该系统可以有效地提高地质分析工作的直观性与准确性,对瓦斯灾害的预测及定位事故发生点具有较大的指导意义.
In order to express the complex geological structure of coal mine and to reflect the spatial relationship between the geological structure elements more accurately, the 3D geological modeling and visualization application of the coal mine are studied.According to the fault block modeling, the fault model is used to correct the block boundary A complete coal geological body model is synthesized and finally a multi-layer three-dimensional geological model based on the surface model is established.Based on this, a practical system is established by using OpenGL technology.The application results show that the system can effectively improve the visualization of geological analysis Sex and accuracy, the prediction of gas disasters and the location of the accident has a greater guiding significance.
