　　According to data from the United States Geological Survey, China ranks fourth in the world in terms of iron ore reserves, with 20 billion tons. However, most of the iron ore in China has low iron content, only 25% -40%, commonly known as "poor ore". At present, China's poor ore accounts for 80% of the total reserves. Using this type of iron ore to produce steel will face problems such as difficult extraction, poor quality, and high energy consumption. In addition, a large amount of exhaust gases such as sulfur dioxide and nitrogen will be generated during the production process, seriously polluting the environment. Therefore, China's iron ore has to rely on imports from abroad.

　　According to relevant data statistics, in 2020, 82% of China's iron ore needed to be imported from abroad, surpassing its dependence on oil and natural gas. Among the imported iron ore, 67% is imported from Australia, and the amount of iron ore imported from Australia has reached 1.17 billion tons, ranking steadily in the world.

　　For buildings and structures with three or more floors, observation points should be set up in the design requirements. For artificial and soil foundation (sand foundation), settlement observation should be set up. During construction, observation and recording should be carried out on schedule or according to the progress of each floor until completion.

　　With the development of industrial and civil construction industries, various complex and large-scale engineering buildings are increasing. The construction of engineering buildings changes the original state of the ground and exerts certain pressure on the foundation of the building, which inevitably causes deformation of the foundation and surrounding strata.

　　In order to ensure the normal service life and safety of buildings, and to provide reliable data and corresponding settlement parameters for future survey, design, and construction, the necessity and importance of building settlement observation have become increasingly apparent.

　　The current regulations also stipulate that settlement observations must be conducted on high-rise buildings, towering structures, important ancient buildings, foundations of continuous production facilities, foundations of power equipment, landslide monitoring, etc. Especially in the construction process of high-rise buildings, settlement observation should be applied to strengthen process monitoring.

　　Guide reasonable construction procedures, prevent uneven settlement during the construction process, provide timely feedback information, and provide detailed first-hand information for the survey, design, and construction departments to avoid damage to the main structure of the building or cracks that affect the functional use of the structure caused by differential settlement, resulting in huge economic losses.
