灵便式M型采矿船的设计研究

Study on Design of Flexible M-form Mining Vessel

当前采矿船普遍存在船型、推进、扬矿等方面的问题。文章提出一种新型的灵便式M型采矿船的设计方案。该设计将现有单体采矿船船型改为M型船,提高了采矿船的稳性、快速性,增大了甲板面积和矿舱容积;将传统的多螺旋桨推进方式改为使用侧推器侧推方式,增加了采矿船的灵活性,可实现船舶准确定位,减少风浪对船体的影响;根据伯努利定律,改变硬管和泵的布置,使用树杈硬管和射流泵,减少矿石对泵体的损伤,延长设备的使用寿命,提高经济性。通过模型试验,对该设计的科学性进行了验证。本设计产品适用于海上采矿技术,为我国矿产资源开采和海上军事战略方面提供了新思路。

The mining vessels at home and abroad are facing many problems in the aspects of hull form, propulsion and mine lifting. To solve these problems, this paper puts forward a new design scheme of flexible M-form mining vessel. The design changes the existing single mining ship type into M-form ship, which improves the stability and rapidity of the mining vessel, and increases the deck area and the capacity of the ore compartment. The traditional multi-propeller propulsion mode is changed to lateral thruster, which increases the flexibility of the mining vessel, realizes the accurate positioning of the ship, and reduces the influence of wind and waves on the ship. According to Bernoulli’s law, Changing the arrangement of hard pipe and pump and using the tree branch hard pipe and jet pump to reduce the damage of ore to pump body extend the service life of equipment, and improve economy. Through the model test, the scientific nature of the design is verified. This design is suitable for offshore mining technology and provides new ideas for China’s mineral resources exploitation and maritime military strategy.
