每日一词|深海重载作业采矿车“开拓二号” deep-sea heavy-duty mining vehicle "Pioneer II"

中国深海重载作业采矿车海试水深突破4000米，标志着中国深海矿产资源开发关键技术取得重大突破。由上海交通大学自主研制的深海重载作业采矿车工程样机“开拓二号”成功完成海试。“开拓二号”连续完成5次着底采矿，实现深海重载作业采矿车海试水深首次突破4000米，最深达4102.8米。

China's deep-sea heavy-duty mining vehicle has completed a sea trial at a depth exceeding 4,000 meters, marking a significant breakthrough in the country's deep-sea mineral resource development technology. The trial was conducted by "Pioneer II", an engineering prototype developed independently by Shanghai Jiao Tong University. "Pioneer II" completed five diving and seabed mining operations, including a record-breaking dive to 4,102.8 meters, marking the first time a Chinese deep-sea heavy-duty mining vehicle conducted trial operations at depths exceeding 4,000 meters.

【知识点】

“开拓二号”是上海交通大学自主研制的深海重载作业采矿车工程样机。2021年，上海交通大学海洋工程团队研制的深海重载作业采矿车“开拓一号”，搭载于“向阳红03”号科考船，在我国南海西沙海域成功完成了1300米深海试验。

新一代深海重载作业采矿车“开拓二号”，主要由深海采矿车主体、大承载光电复合脐带缆和重载布放回收绞车等多型装备组成，长6.0米，宽3.0米，高2.5米，重量约14.0吨，设计作业水深6000米，具备深海多金属结壳、多金属结核与深海硫化物等多类型矿产综合开采能力，技术性能达到国内领先、国际一流水平。
