Abstract: In the process of coal mining, most mining enterprises have problems such as poor management level, serious waste of resources and low work efficiency.BIM technology is a 3D visual modeling technology in the engineering field in recent years.BIM technology is applied to coal mine engineering to create a high-dimensional, high-precision and high linkage information model and develop the research concept of digital mine.It plays an important role in solving this problem.Taking a coal mine in Guizhou province as the research object, this paper establishes the mine geological model, mine field development positioning axis and mine main component model family library, and preliminarily generates the digital mine BIM model.The practice results show that it is feasible to apply BIM technology to mine digital modeling, which can improve the integration of human, machine, environment and management in the mine.This technology has strong applicability in the field of coal mine, can accelerate the visualization research process of digital mine, and can be used as an important means to realize digital mine.
