【摘要】：随着金属矿山生产管理现代化、数字化进程的发展,可视化生产管理、交互式的安全生产演练及培训已成为未来矿山数字化建设发展的趋势。而虚拟现实作为近年来新兴的技术,已经逐渐成熟。将虚拟现实技术与金属矿山“六大系统”建设结合,在一个三维虚拟井下环境中演练灾害事故的发生,将很大程度提高井下作业人员的安全逃生意识,降低井下事故的发生率,有着极其重要的意义。本文首先提出了3D虚拟金属矿山井下紧急救援演练平台总体框架的设计,包括平台的功能架构、技术架构、数据库设计以及基础地图信息库的组织。在灾难事故演练过程中,平台能够依据井下环境及人员健康评价方法,做出最优逃生决策。然后研究了金属矿山三维基础数据的处理及建模过程。通过与AutoCAD应用程序交互,提取并采用适当的算法处理井下地图信息。同时,提出了一种基于回滚的容错处理机制来弥补算法的不足与缺陷,使得演练平台能够以AutoCAD图作为基础数据,以XML格式储存在地图信息库,为最优路径规划策略、可视化场景建模提供直接数据来源。在可视化建模方面,研究了基于3DS MAX的巷道建模。采用可编辑多边形建模方式,通过巷道交叉处平滑处理计算,适当材质及渲染方式的选择,建立金属矿山井下可视化场景。最后,以广东省凡口铅锌矿为应用背景,凡口铅锌矿井下AutoCAD图为基础数据来源,初步搭建了凡口铅锌矿井下逃生救援演练平台。
[Abstract]:With the modernization of production management in metal mines and the development of digitization process, visual production management, interactive safety production drills and training have become the trend of the development of digital mine construction in the future.Virtual reality as a new technology in recent years, has gradually matured.Combining the virtual reality technology with the construction of "six systems" in a metal mine and practicing the occurrence of disaster accidents in a three-dimensional virtual underground environment, the safety escape consciousness of underground operators will be greatly improved and the occurrence rate of underground accidents will be reduced.Have extremely important meaning.This paper first presents the design of 3D virtual metal mine underground emergency rescue platform, including the functional structure, technical architecture, database design and the organization of the basic map information database.In the process of disaster and accident drill, the platform can make the optimal escape decision according to the underground environment and personnel health evaluation method.Then, the process of processing and modeling of three-dimensional basic data in metal mines is studied.By interacting with the AutoCAD application, the paper extracts and processes the downhole map information with the appropriate algorithm.At the same time, a fault-tolerant processing mechanism based on rollback is proposed to make up for the shortcomings and shortcomings of the algorithm, so that the drill platform can use AutoCAD diagram as the basic data and XML format to store in the map information base, which is the optimal path planning strategy.Visual scene modeling provides a direct data source.In visual modeling, the roadway modeling based on 3DS MAX is studied.The visual scene of metal mine underground is established by using editable polygon modeling method, smooth processing calculation at roadway crossing, selection of proper material and rendering method.Finally, based on the application background of Fankou lead-zinc mine in Guangdong province, and the AutoCAD map of the mine as the basic data source, a preliminary platform for rescue and rescue under the Fankou lead-zinc mine was set up.
