Intelligent mining is the main content of promoting the high-quality development of coal industry. The innovative development of Internet +, big data, virtual reality and other advanced information technologies as well as the gradual industrial application of 5G and other advanced communication technologies have opened a new era of intelligence in the coal industry, which is currently in the research and development process of transparent working face.

The book consists of 14 chapters.

Chapter is the application overview, which introduces the research background, purpose and significance of this book through the virtual reality assembly technology and system as well as the three machines in fully mechanized mining face monitoring and dynamic planning in the fully mechanized mining face under the virtual reality environment.

Chapter is the overall design of the system, which proposes a design and operation mode of the production system of fully mechanized mining face based on digital twin. In fully mechanized design and monitoring service system, driven by factors of production management configuration, process simulation and real-time monitoring, etc. in the physical and virtual of fully mechanized working face, fully mechanized design and monitoring service system of fully mechanized working face of iterative operation, to achieve full elements, whole process, full integration and data fusion, to achieve the optimal configuration and equipment production system together; the purpose of safe and efficient mining. The technical framework and key technologies of the three stages are described in detail.

Chapter introduces the virtual simulation element model conversion technology and the establishment of the model library, and in accordance with the internal structure and the working characteristics, optimize the technology of CAD model transformation and 3 on 3d Max scene and animation technology is established by virtual dismounting module and scene simulation module of virtual reality database, provides a foundation for the establishment of the system, and can continue to expand the relevant function later on down the line.

Chapter puts forward the method of virtual assembly based on OSG, manipulation, recording and playback of the path, the model reset, automatic positioning constraints, network collaborative assembly and parts introduces the concrete methods of assembling and disassembling demo automatically carried out theoretical research and through the programming to realize the corresponding function, based on this method to establish the virtual assembly system, based on OSG can meet user demand for virtual assembly.

Chapter puts forward the virtual assembly method based on UG and uses the product information extraction technology to extract parts information and assembly relation information, and realizes the transformation from assembly model to virtual assembly planning model. According to the modularization method, the methods and algorithms of key data planning, automatic assembly, assembly sequence planning and dynamic simulation of assembly process are studied, respectively.
