139.1 Introduction

With the rapid development of the computer and network technology, the coal mine safety monitoring technology is constantly popularized and applied. The coal mine enterprise is gradually developing on the concentrated management schema by collectivization. So, to the coal mine production and safety monitor, we not only think monitor some side safety factor of the coal mine production, but also take the coal mine production as a whole to think and form the comprehensive safety monitor system (Lin 2010). The sub-systems of the safety monitor system are all separated, and every sub-system forms a system, then the system has the difficult maintenance, the poor reliability, the low sharing and utilization of the information resource, and it is difficult to be unified management (Qiao 2010; Wang et al. 2010). So, the high integration of the coal mine safety and production comprehensive information, 3D visualization of the safety production management and dispatching, and the digital coal mine development are the information development trends of the coal mine enterprise.

In the information management of the coal mine enterprise, the enterprise not only need to set up the digital coal mine, but also need to realize the 3D visual coal mine platform, which highly integrated the geological gauge information, the project information, the production information, the safety monitoring information, the mine worker positioning information, the comprehensive automation monitoring information and other office system information (Peng-fei and Jun 2009; Liang et al. 2010; Jun 2010; Han and Tian 2009). The relevant data, diagram and chart which are needed are indirectly queried by the visual and real dynamic 3D figure. So, the development trends of the coal mine informationization are digital, informationization and 3D visualization.

In this paper, according to the software, hardware and network of the coal mine enterprise, we designed the logical structure and system framework of the unified integrated software platform. This logical structure and system framework generates the 3D topography, mine tunnel stereoscopic drawing and excavated stereoscopic drawing based on the data of the geological survey and engineering. The data and information about the monitoring and production are showed by integration on the 3D stereoscopic drawing. We also tried a pilot to develop a system and put it to application according to this logical structure and system framework.

139.2 The Status of 3DGIS Research and Application

3DGIS technology can seamlessly integrate spatial data and its related attributes information, visualize graphs and images, and comprehensively analyze multi-source and heterogeneous data (Fan et al. 2010). At present, there are many commercial 3DGIS software firms which are already put forward the 3DGIS platform, such as Mapinfo and ArcGIS, etc. But these platforms mainly are used to the traditional survey domain (Wang 2010). The technology of synthesizing, integrating and showing of the 3D data and information of safety information is popular to focus on by the national coal mine research institutes, and this technology is rapidly developed (Yu 2011; Zhi-fan 2007). It is very difficult to develop the comprehensive platform of coal mine safety production data based on 3DGIS, and it need the developed members have the good mine profession knowledge and the rich experience of developing the enterprise software to integrate their data and information (Fu et al. 2003). The main member of all mine enterprise software development have the mine special background, and they are good at develop the profession software about the mine enterprise interior business flow and model, then their technology ability are not enough to integrate the safety information into an unified data comprehensive platform based on 3DGIS. The integrated software based on 3D lags the market needs.

139.3 The Principle of Developing the Coal Mine Comprehensive Information System Platform

The principles of developing the coal mine comprehensive information system platform are as follows (Gan et al. 2003; Sun et al. 2009).

139.3.1 Entirety

The coal mine informationization construction is the information system platform development, and it is not the sub-system development or the profession system development. The system platform development needs the platform have the more entire information and function, this avoid to cause new information islet. The system platform not only contents the safety and production management of the building mine and production mine, but also the coal mine manage itself.

139.3.2 Advancement

On the premise of contenting the entirety, the whole technology should be advanced in the internal, and it will not lag in 5–10 years. Advancement not only presents improving the mine safety production management and the enterprise production, but also expresses the enterprise management level and the enterprise image.

139.3.3 Maturity

The whole system platform has the mature function and technology, and the successful using example. This ensures the stability and reliability of running and using the system platform.

139.3.4 Extension

As a system platform, its extension ability shows whether it has the long using life or not. The system platform can join up the new system and make it perfected constantly according to the enterprise development demand.

139.4 The Design of the Logical Structure and System Framework of the Coal Mine Comprehensive System Platform

139.4.1 Logical Structure of Platform

The mine geological survey information, engineering information, production information, safety information, equipment working status information will be integrated into the comprehensive system platform. So, the centralized storage application, distributed management, unified data and sharing by authority should be as the goal of the system platform, and the hierarchical logical design is adopted, the system platform is divided three layer logic structures from top to bottom, that is the data layer, the business layer and the user layer. It shows in Fig. 139.1.

The data layer mainly includes the data organization, the data storage and the data management from many systems. The data to organize, store and manage includes the geological survey data, the production information, the safety monitoring information, the mineworker positioning information, the report forms, the tube bundle monitoring information and the video monitoring data, etc.

The business layer mainly processes the business logic and data. The business logic and data to process includes the geological data processing, the production data processing, the real monitoring data processing, the report form data analyzing and processing, the tube bundle monitoring data processing and the alarm data processing.

The application layer mainly expresses the information result. The expressing information result includes the information publishing, the information querying, the information browsing, the report form data inputting and the system maintaining.

The data layer, business layer, the application layer join and interrelate each other in the system.

139.4.2 The System Framework

The geological information, information, production information, safety information, equipment running status information will be queried and showed in the system. The 3D visual technology can realize the visual showing, but the 3D showing needs a certain software to support. To the users, the developed system should be flexible and not be restricted by the platform. So, the whole system framework is based on the B/S and C/S model, and the users can feel the information management, the 2D and 3D image management and the information sharing in the B/S model. The system framework shows in Fig. 139.2.
