BIM is building information modeling, and architects can process and analyze some data in the virtual building model, so as to design the building scheme. BIM technology contains three connotations. First, it is a technology to realize digital representation of data, which transforms all real building parameters into information on simulated substitutes and processes them. The second is to improve the information, intelligence and technology of construction engineering. BIM technology is an innovation of traditional architectural analysis methods. Through the input, updating, modification and testing of model data, designers can make targeted improvements and optimizations in all aspects of each project to the maximum extent, so as to make the whole architectural design scheme more perfect and meet the diversified needs of users to the maximum extent. Third, BIM technology creates an atmosphere of enjoyment. All data are open and transparent, and can be shared and copied. Therefore, all the links are connected, and all the people involved in the design can communicate in time, communicate in real time, enjoy resources and work together for a better design scheme. Such a technology, with fully enjoyed data and updated in time, runs through this construction project horizontally, allowing more people to participate in all links, which is conducive to mutual supervision. At the same time, * * * promoted the continuous improvement of the design, improved the engineering efficiency to a certain extent, reduced the engineering cost, and achieved good building energy-saving effect.

BIM technology can realize N-dimensional omni-directional stereoscopic vision, the distribution state of each project in different depths and ranges, the construction process and later operation state of each project, energy saving and environmental protection data, climate change parameters and so on. Can be presented in n-dimensional form. In this way, the construction personnel in charge of each part and the owner can exchange information more effectively, which is also conducive to the system optimization and overall arrangement of the whole project, thus optimizing the energy-saving effect of each link in detail. And BIM technology makes the whole design more intelligent. There are many working procedures and complicated steps in coal mine engineering. BIM technology can only be related to automatic statistics, and to a greater extent, it can link all links together in an orderly way, realize the intellectualization of construction process and management operation, improve energy conservation and emission reduction in design, and create the vision of green mines. Virtual model covers many architectural elements, such as material selection, building structure, concrete data of construction and performance utility. Therefore, BIM technology can really help designers to achieve energy saving in the design scheme.
