COLLECTING AND LIFTING METHODS OF MANGANESE NODULE AND MINING DEVICE

摘要

Disclosed herein are a mining device for mining manganese nodules, which comprises a mining surface ship, a collector, and a recovery device, and a collecting and lifting method using the device. Without having a rising pipe between a collector which mines manganese nodules scattered around sea bottom and a mining surface ship, manganese nodules are carried a net-type or a box-type recovery device. In the mining device, the collector is operated by a control cable form the mining surface ship or by the remote control of an ultrasonic transceiver. Manganese nodules are discharged by a collector to a recovery device or sucked by a suction pipe, which is installed at a recovery device and attaches a small ROV (Remote Operating Vehicle) at the end. After stacking manganese nodules, the recovery device is lifted to the mining surface ship by a lifting cable or a buoyancy controlling device. It would be a collecting and lifting method and a mining device which carries manganese nodules efficiently when developing mineral resources like manganese nodules in the deep-sea bottom.
