这些就是小编今天想跟大家分享的内容，自然资源砂石虽然前景十分广阔，但也要合理开采，了解采沙船使用的情况外，我们更注意我们的环境。

The mining boat as the name implies is the tool we use in the process of sand mining, the sands we gather are the bare rocks in nature, and the common effects of natural and man-made factors such as sunlight, wind and rain, frost, and differentiation into tiny particles, we also come to understand the structure principle of the sand mining and what the principles should be followed.
First, the construction principle of the sand mining is:
1, mining system: by the bucket chain, main drive, bucket rack and so on, mainly used to complete the topsoil and ore excavation operations.
2, beneficiation equipment: The cylinder sieve, the selection of gold combination spiral chute, coarse selection equipment and selection of equipment, for the completion of ore washing, crushing, screening, coarse selection and selection of homework.
3, tailings dump system: by belt conveyor, sand pump and so on, for conveying the dumping of gravel and tailings.
4, water supply and medium-ore conveying system: by pumps, sand pumps, pipes, sand pump pipe and other components, for water supply and ore pulp conveying.
5, winch System: Lifting winch, first rope winch, lifting anchor winch, transverse winch and landing bridge winch, etc., used to enter the ship, the ship, the ship, the ship's transverse movement and bucket rack, pile column, landing bridge and so on.
6, Lifting equipment: The bow crane, the main driving crane and other lifting equipment, to complete a variety of lifting work.
7, Hull and hull facilities: by the flat-bottomed ship and various hull facilities, used to install the Gold Ship's various equipment and structure, so that the gold ship can float smoothly on the water.
8, Upper steel structure and housing: by the main truss, front mast, rear mast, control room, office, plant, staircase and landing bridges, etc., to support and decorate a variety of facilities and equipment, to ensure that the gold ship in the operation of convenient, safe and reliable.
The second is what principles should be followed:
1, make full use of surface water, reasonably develop groundwater, to achieve the integrated arrangement of groundwater and surface water;
2. According to the water recharge capacity of each aquifer, the number of wells and the amount of mining should be determined, and the layering of water, shallow, medium and deep, reasonable layout;
3, must combine with the drought and waterlogging alkali salty management, unify plan, do not only protect the irrigation, but also reduce the underground water level, prevent the alkali stain; both mined groundwater and vacated underground storage capacity, and the flood season can store rainfall and ground runoff, and create conditions for the treatment of waterlogging Zhi.
 These are small series today want to share with you the content, Natural resources sandstone Although the prospects are very broad, but also to reasonable mining, to understand the use of sand mining situation, we pay more attention to our environment.
