中文摘要：

大洋深海蕴藏着资源丰富、种类繁多的矿产资源。其中多金属结核矿产以其高价值和储量丰富的特点,成为首要勘探和开采的对象。但是深海海底动态、复杂且具有危险性的海洋环境,制约着深海采矿技术的发展。应用仿真技术模拟深海复杂环境,及其与采矿设备的交互,成为深海采矿技术发展的一种途径。采用HLA仿真体系构架,在收集和整理我国深海开辟区的区域地形及海洋环境数据的基础上,综合已有的多金属结核勘探资料,仿真多金属结核采矿过程中采矿车和海底环境的交互作用,完成深海采矿环境仿真系统原型的开发。应用环境地学仿真技术,建立深海海底数字地形模型、海底底质软泥的承压和剪切力模型、深海近底层流模型、采矿车的动力学和运动学模型。通过消息发布与订购、时间管理、联邦管理和可视化输出,模拟仿真深海环境对采矿作业的影响。仿真系统原型由六个联邦成员组成,通过计算联邦成员之间的交互作用,分析大洋深海海底环境因素对采矿作业的影响。

英文摘要：

Recent research in the deep-sea has identified rich ore deposits that may be economically extractable through the development of a deep-sea mining （DSM） industry.The poly-metallic nodule has the potential to become a significant mineral resource.The development of deep sea mining is limited by the execrable,dynamic and complex environment.The aiming mining tenements are located deep seabed with operations taking place in an environment with extreme conditions with many uncertainties about potential environmental impacts.So modeling and simulation of deep sea mining system has become a promising approach to develop,analyze and illustrate the mining procedure.The concept and prototype for environmental impact modeling and simulation of a test mining system were proposed by the COMRA （China Ocean Mineral Resources R D Association） integrated with the investigated data of the working area.The purpose of the project is to provide reasonable modeling and simulation system as a case study to recognize and illustrate the primary deep sea environmental issues surrounding DSM.In the prototype system six HLA Federations were developed and executed standing for poly-metallic nodule pilot mining procedure.Along with the HLA simulation procedure of mining,the impact of deep sea environment was run through message exchange,time management,federal control and visualization based on RTI.The environmental federal is constructed under the model of deep sea environment.
