## 5 Case Study  
To verify the concept, connotation, characteristics, architecture and technical requirements of the mining technology collaboration platform proposed in Section 4, it is used to guide the development and implementation of the mining technology collaboration platform for the construction of digital mines at Fujian Makeng Mining Co., Ltd.  
The Makeng Iron Mine of Fujian Makeng Mining Co., Ltd. (hereinafter referred to as \"Fujian Makeng Iron Mine\") is located in Longyan City, Fujian Province, China. It is one of the famous extra-large magnet deposits in China. The proven geological reserves of iron ore are 434 million tons, with an average iron grade of 37.99% and the total metal content of symbiotic and associated molybdenum resources is more than 80,000 tons [53]. It has a scale of 5 million tons of iron ore annually. At present, the construction of a digital mine of Fujian Makeng Iron Mine has achieved certain results, including the construction of the underground monitoring and controlling system, the construction of the underground personnel positioning system, the construction of the underground communication system, the construction of the underground emergency avoidance system, the construction of the underground forced air self-rescue system and the construction of the underground water supply rescue system, enterprise comprehensive management information construction, KJ293 (A) railway locomotive transportation monitoring system construction, fan remote control system construction and tailings reservoir online monitoring system construction. However, the mining design is still based on two-dimensional computer-aided design (CAD) software, the mining planning is compiled by EXCEL and the ventilation management depends on the technical and experience level of the ventilation technician. The duties of each business are not clear; the phenomenon of overlapping and duplication of each business is a serious problem; lack of necessary communication and communication between participants is not smooth and the phenomenon of rework is a serious problem. The related drawings and documents formed by each business are scattered throughout the hands of professional technicians and the version is confusing, lacking standardization and unified management and so forth.  
Therefore, to solve the problems existing in the business stages of production exploration, mining planning and design, survey and acceptance of Fujian Makeng Iron Mine, based on the concept, connotation, characteristics, architecture and technical requirements of the mining technology collaboration platform proposed in Section 4, this case study first performed a requirement survey and analysis of the present situation of the Fujian Makeng Iron Mine mining production process, including the organizational structure of all participants, business and business posts, business processes,business post responsibilities and input and output data under business post responsibilities; second, the design and development of the mining technology collaboration platform of Fujian Makeng Iron Mine were performed; finally, the operation and implementation of the mining technology collaboration platform of Fujian Makeng Iron Mine were carried out.
