Subsidence data acquisition methods are crucial to mining subsidence research and an essential component of achieving the goal of environmentally friendly coal mining. The origin and history of the existing methods of field monitoring, calculation, and simulation were introduced. It summarized and analyzed the main applications, flaws and solutions, and improvements of these methods. Based on this analysis, the future developing directions of subsidence data acquisition methods were prospected and suggested. The subsidence monitoring methods have evolved from conventional ground monitoring to combined methods involving ground-based, space-based, and air-based measurements. While the conventional methods are mature in technology and reliable in accuracy, emerging remote sensing technologies have obvious advantages in terms of reducing field workload and increasing data coverage. However, these remote sensing methods require further technological development to be more suitable for monitoring mining subsidence. The existing subsidence calculation methods have been applied to various geological and mining conditions, and many improvements have already been made. In the future, more attention should be paid to unifying the studies of calculation methods and mechanical principles. The simulation methods are quite dependent on the similarity of the model to the site conditions and are generally used as an auxiliary data source for subsidence studies. The cross-disciplinary studies between subsidence data acquisition methods and other technologies should be given serious consideration, as they can be expected to lead to breakthroughs in areas such as theories, devices, software, and other aspects.

As a technological concept that promises to seamlessly connect the real and virtual worlds, the concept of the Meta universe has been hotly debated by a large number of Internet users even before it was implemented. Considering the particularity of this concept, it is not difficult to imagine that this new industry, once launched, will have a near revolutionary impact on the entire social network. This paper will list case studies and questionnaires as survey methods. This article summarized the industry’s status and investigated regional opinions about the Meta Universe, which gives an industry profile to the relevant company or the company that intended to participate in the production of Meta universe. Thus, they can decide the direction of development and which strategy to utilize in the program. In addition, some suggestions for potential problems in the metaverse field in the future, the aspects that need to be paid attention to for the anti-addiction mechanism and legal regulation are all includ in this paper for the reference of relevant enterprises, so as to bring better user experience for the masses.
