摘要:
深海采矿作为新领域资源重点开发项目，国外已开展部分试验研究，国内现阶段仅停留在重点设备部件级功能验证，还未开展过系统整体联动，距离海洋油气等正在进行的规模化商业开采还有很大距离。本文以深海采矿系统整体联动模型为基础，与海洋油气工程作业平台技术模型进行对比，对整体联动风险点进行深度分析，并根据重点风险部件开展其悬挂模式、力学模型研究，探讨深海采矿系统整体联动时应急撤离的策略。研究总结了深海采矿系统整体联动的特点，提出了管道摇摆幅度超出设计范围、平台升沉行程超出伸缩冲程范围等两大关键风险点、提升硬管受力分析方法和对应的应急撤离方案，对深海采矿工程总体设计和工程实施具有指导意义和参考价值。

Abstract:
Deep-sea mining is a new and important area of resource development. Some experimental studies have been carried out abroad. At present, studies in China still remain at the functional level of individual key equipment instead of the overall system, which is still far from largescale commercial exploitation of offshore oil and gas. This study compared the overall linkage model of the deep-sea mining system with the technical model of the offshore oil and gas engineering operating platform, conducted an in-depth analysis of the overall linkage risk points, researched the suspension mode and mechanical model of key risk components, and discussed the emergency evacuation strategy of the deep-sea mining system under the overall linkage model. This paper summarizes the characteristics of the overall linkage of the deep-sea mining system and proposes two key risk points, such as the pipeline swaying range exceeding the design range and the platform heave stroke exceeding the telescopic stroke range. It also presents an analysis method of lifting hard pipe stress and a corresponding emergency evacuation plan. The overall design and implementation of deep-sea mining projects are of guiding significance and reference value.
