Smart mine solutions and their successful applications

(2) Time and Space service: GIS and BIM technologies are used to build a comprehensive mine database based on unified data standards, with spatial and geographic location as the main line, layer management as the organizational form, and the goal of creating a 5D digital twin for mines. Provide services and tools such as two-3D integrated location services, collaborative design services, configuration services, 3D visual simulation, mining engineering and equipment life cycle management for smart mine applications, to achieve a map integration and fusion, a map collaborative design, a map collaborative management and a map decision analysis.

(3) Fusion linkage: Through software definition, the data fusion and intelligent linkage of all business systems above and below the well are realized, and the strong real-time correlation of human, machine, environment and management information is achieved.

(4) Intelligent decision-making: The use of big data and artificial intelligence and other technologies to iteratively upgrade the intelligent analysis and auxiliary decision-making of coal mine safety, production and management.

02 Smart mine overall structure

Smart Mine Internet of Things Open Platform (RED-IOT®) is a smart open sharing platform developed by Huaxia Tianxin for the construction of smart mines in China, and is the top-level design of smart mines. Based on the software-defined concept of open sharing, RED-IOT® integrates GIM (GIS+BIM) space-time map, industrial Internet of Things, cloud computing, big data, artificial intelligence, mobile Internet, virtualization, network communication and other technologies to deeply integrate mine informatization and automation. It can complete accurate real-time collection of all data of mining enterprises, highly reliable network transmission, standardized integration, visual display and real-time dynamic analysis, and realize production process automation, safety monitoring digitization, data application modeling, production management visualization, and intelligent process control. And the hidden dangers, failures and danger sources of human-machine-environment are predicted in advance, prevention and emergency joint disposal, so that the whole mine has self-learning, analysis and decision-making ability.

The overall architecture of smart mine is based on the four-layer architecture system of Huaxia Energy Industrial Internet of Things, which is mainly composed of the perception implementation layer, the network transmission layer, the smart mine operating system platform layer (RED-MOS) and the intelligent application APP layer (RED-AppStore).

(1) Perception and execution layer: Using the Internet of Things technology, it can fully perceive the position and status of underground people, machines, rings, etc., and can control the equipment.

(2) Network transmission layer: mine wired and wireless transmission network, in addition to the security monitoring system independent networking, other systems are using the field bus fusion networking mode, on the basis of network resource unified protocol to achieve efficient and reliable data transmission.

(3) Smart Mine Operating System platform layer (RED-MOS) : It is an open and scalable smart mine kernel and operating system based on the mine cloud data center, which realizes the access of various sensing data downward and provides services and tools for the development of smart mine APP upward.

(4) Intelligent application layer (RED-AppStore) : It can realize the integration of automation and information application for mine production, safety, operation and management, and decision analysis, and realize mobile Internet applications and services based on intelligent terminals. Finally, the integration, intelligent linkage and dynamic expansion of application resources are realized, and data management, decision making and service are truly achieved.

In short, smart mine construction forms a comprehensive smart mine management and control platform for enterprise safety, production and operation management through vertical penetration, horizontal correlation, comprehensive integration and fusion innovation of each subsystem. The platform can operate safely, stably and reliably as a whole, and the subsystems can also operate independently. The failure of the platform shall not affect the operation of the subsystems, and the failure of the subsystems shall not affect the operation of the platform.

0 3 Smart mine operating system platform

The company has successfully developed the intelligent Mine operating System platform (RED-MOS) against the industrial Internet of Things platforms of ABB, Siemens and other internationally renowned enterprises. Smart mine operating system platform (RED-MOS) is the core of smart mine construction, which not only realizes the integration and fusion of multi-source heterogeneous sensing data, opens up the barrier between sensing data and intelligent applications based on sensing data, but also realizes the deep integration of informatization and automation in one platform, providing technical support for the energy industry to realize the integration of the two. As shown in Figure 3. In October 2018, the platform passed the scientific and technological achievements appraisal of the China Coal Industry Association, and the appraisal jury was composed of academician Liu Yunjie, an expert in the field of network and industrial Internet of Things, and Academician Wang Guofa, an expert in the field of domestic mining and smart mining, and other experts. The expert committee unanimously agreed that the platform reached the international leading level and filled the domestic gap.
