英文摘要	煤矿生产数据具有动态变化的特性,平面数据、剖面数据和三维地质模型需要随着矿山开采不断进行动态的修正和更新,使其对地下生产对象的表达越来越精确.但是,现阶段研究三维地质模型以静态建模为主,对模型数据更新处理的操作复杂,需要进一步深入研究三维模型的动态修正问题.研究提出利用最新的生产数据、修正的模型数据等对三维地质模型进行动态修正的流程及技术框架;对实现过程中所用的相关技术进行了研究,包括平面-剖面对应算法、膨胀搜索算法、样条曲面算法、平滑过渡算法等关键技术,实现了三维模型的局部动态修正;通过应用模型动态修正技术,使煤矿三维地质模型能够及时更新各类数据,更加真实的反映煤矿当前生产状况,提高了三维地质模型的动态更新自动化程度及实用性.相关成果在王家岭煤矿进行应用实践,证明了研究方法的有效性.; Because of the dynamic characteristic of the production data in coal mine, plane maps, section maps and the three-dimensional geological model of the coal mine should be dynamically corrected and updated, and then the underground objects can be controlled more and more accurately. However, the existing researches of three-dimensional geological models are based on static modeling method, which led to the complexity of the model updating process. It's necessary to study the dynamic modeling method further. Firstly, the new theory of dynamic correction of coal mine 3D geological model using the latest production data and correction model data was presented. Secondly, based on the 3D geological model data, the key techniques used in the system implementation were studied, such as plane-section corresponding algorithm, expanding search algorithm, partially curved surface algorithm, smooth transition algorithm, etc. And the partially correction and updating of coal mine 3D model was realized. Finally, the established coal mine 3D geological model can be updated and corrected using various kinds of the latest data in time, and can correctly reflect the current situation of the production. Using those techniques, the automation of dynamic updating and practicability of the 3D geological model would be improved. The practical application of relevant results in Wangjialing Coal Mine proved the validity of research methods.; EI; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 5; 918-924; 39
