Abstract: Open-pit engineering project has the characteristics of complex design,multiple production links,dynamic development
of engineering and multi-source distribution of information,etc. The traditional project management mode is difficult
to share mine construction project information,resulting in many engineering problems such as design change and engineering
rework. Based on building information modeling (BIM) technology,this paper deeply analyzes the connotation of BIM design in
the field of open pit construction engineering design,studies the framework of BIM mine construction plan,and carries out application
exploration with the example of Xinjiang Mining Hongshaquan No. 2 Mine of Guoneng Group. The results show that:
① The BIM design connotation of open pit construction engineering is based on BIM technology,integrating the ten key technologies
of collaborative design and true three-dimensional information,and carrying out the design of open pit engineering from
multiple perspectives such as safety management,design quality,engineering construction,green intelligence and technical support;
② General software end,professional software end,third-party software end,application end and data interaction platform
jointly constitute the open pit BIM design framework. Its functional architecture follows the pyramid structure of " top-down
step-by-step planning,bottom-up distribution and implementation",and its design data standard is composed of classification
coding,data model and information transmission;③ The BIM design application practice of Hongshaquan No. 2 Mine shows
that the technology has significantly improved the quality of design as well as the levels of safety management,intelligent control
throughout the entire process and green mining.
