一，以潜水铁砂泵为主的水力开采方式：
First, the hydraulic mining method based on submersible iron sand pump.
使用潜水铁砂泵为主的开采方式，其核心在于抽取铁矿砂时选用的铁砂泵为潜水铁砂泵，其他配套围绕它配置。
The core of the submersible iron sand pump is that the iron sand pump is used as the submersible iron sand pump when extracting iron ore, and other matching pumps are arranged around it.
其配置特点是：铁砂泵过流部件为耐磨合金材质，高效耐磨，机组放置在水面之上，便于维护。可以配套柴油机或电机驱动，相对潜水铁砂泵的流量更大，输送距离更远。缺点是：配套设备较潜水铁砂泵多，操作复杂，抽沙平台也略大。如选用柴油机，单位时间的成本也比潜水铁砂泵略高。
Its configuration features are: iron sand pump flow parts for wear-resistant alloy material, high-efficiency wear-resistant, set on the water surface, easy to maintain. It can be matched with diesel engine or motor drive, and the flow rate of the submersible iron sand pump is larger and the transportation distance is farther. The disadvantages are: the matching equipment is more than the diving iron sand pump, the operation is complex, and the sand pumping platform is also slightly larger. If the diesel engine is selected, the cost per unit time is also slightly higher than that of the submerged iron sand pump.
二，以卧式铁砂泵为主的水力开采方式：
Two, the horizontal iron sand pump is the main way of hydraulic mining.
使用卧式铁砂泵为主的开采方式，其核心在于抽取的铁矿砂时选用的铁砂泵为卧式铁砂泵，其他配套围绕它配置。
Horizontal iron sand pump is the main mining method, the core of which is to select the iron sand pump as the horizontal iron sand pump, other matching around it.
其配置特点是：铁砂泵过流部件为耐磨合金材质，高效耐磨，机组放置在水面之上，便于维护。可以配套柴油机或电机驱动，相对潜水铁砂泵的流量可以更大，输送距离可以更远。缺点是：配套设备较潜水铁砂泵要多，操作要复杂，抽沙平台也略大。如选用柴油机，单位时间的成本也会比潜水铁砂泵略高。
Its configuration features are: iron sand pump flow parts for wear-resistant alloy material, high-efficiency wear-resistant, set on the water surface, easy to maintain. Can be matched with diesel engine or motor drive, the flow rate of submersible iron sand pump can be greater, the transmission distance can be further. The disadvantage is: the matching equipment is more than the submerged iron sand pump, the operation is complicated, and the sand pumping platform is also slightly larger. If the diesel engine is selected, the cost per unit time will be slightly higher than that of the submerged iron sand pump.
