deep-sea heavy-duty mining vehicle "Pioneer II"
深海重载作业采矿车“开拓二号”
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.
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。
