## 5 Case Study
### Requirement Survey and Analysis  
The requirement survey and analysis for the R&D and implementation projects of the mining technology collaboration platform of Fujian Makeng Iron Mine are divided into two phases. In the first phase, through face-to-face interviews, the participants' organizational structure, professional duties, the input and output data under the professional duties and business processes are thoroughly understood; additionally, the business contents and business processes involved in geology, surveying and mining, as well as the application of three-dimensional mining software in various businesses are clarified; then, the problems existing in the requirement survey are analyzed and sorted out and the current situation and existing problems of requirement survey are discussed and confirmed by the focused discussion confirmation method to form a requirement survey report. In the second stage, based on the requirement survey report formed in the first stage, combined with the application characteristics of mine digitalization and informatization, the application technical standards, data management standards and business process standards that meet the mining technical requirements of Fujian Makeng Iron Mine are summarized and formulated, including the data coding system, data management standards, geological business process specifications, surveying business process specifications and mining business process specification. This requirement survey and analysis involved six participants, including Fujian Makeng Mining Co., Ltd. and five construction units, involving a total of 9 departments and 21 departments and the organization structure of the mining technology posts in Fujian Makeng Iron Mine can be found in Reference [54] and Figure S1. Through the requirement survey and analysis of the above two stages, the existing business processes are reengineered to form the documents of the geological business process specification, survey business process specification and mining business process specification of Fujian Makeng Iron Mine [55; 56; 57]. On the basis of the standardized business process, the organizational structure of the mining technology post for Fujian Makeng Iron Mine after the organizational structure reengineering is formed, as shown in Figure 4. Based on the standardized business processes and the new organizational structure of mining technology posts, the duties of each professional post and its input and output data are defined. The surveying business standardization process includes 10 sub-business specification processes, such as a surface control survey, land acquisition survey, topographic survey, shaft and laneway engineering control survey and shaft and laneway engineering survey; the geological business standardization process includes 14 sub-processes, such as prospecting design, drilling logging, laneway logging and geological modeling; the mining business standardization process includes 14 sub-processes, such as mine area division, level division, stope division, development design, mining and cutting design and short hole design. The orebody modeling business standardization flow chart is shown in Figure 5 and the duties and the input and output data of each post in the orebody modeling business process are shown in Table 1.
