Technical Field

[0001] The present invention relates to the field of coal mine foundation engineering construction, and in particular to a coal mine engineering construction management method based on BIM+. Background Art

[0002] At present, there are still the following deficiencies in coal engineering construction: (1) Due to the large scale, long cycle, high investment and many hidden projects of coal mine infrastructure projects, some enterprises focus on engineering and neglect construction, and focus on post-management and neglect pre-management, resulting in many hidden dangers, waste of resources, over-investment and low efficiency in the projects. How to conduct comprehensive and timely effective supervision and process traceability of coal mine infrastructure projects is a difficulty in current construction management. (2) There are many parties involved in the coal mine infrastructure construction process, and the drawings, models and data systems at various stages are chaotic, with different standards and complex management. The various stages cannot form a comprehensive and organic integration, which is prone to inconsistency, mismatch and uncoordination. In addition, the basic results of the previous design cannot be used after the construction is turned into operation, resulting in waste of process assets and increased costs.
