Curvature reflects the size of bending degree of curve. In this paper, we put forward a new relational degree model based on curvature of the two series. The new model satisfies the parallel property and uniform property. It is consistent with the actual situation by comparison to the existing relational models. At the end, we give a case in order to validate the new model.
Belt conveyor is one of main electromechanical systems in the coal transport system, its safe operation plays an important role in the whole coal output systems. As the belt conveyors get longer, quicker and bulkier, the traditional static design method already can not satisfy the requirement of actual engineering. One of problems is that a huge peak belt tension induced by the starting and stopping...
This article establishes mine workers' safety behaviors simulation system through combined virtual reality and mining safety production. The aim is to standardize safety behavior, improve the effectiveness of safety training and accordingly reduce the accidents' occurrence in coal mine. The system is constructed by means of 3D building software. Then, an integrated development in the platform Virtools...
This article establishes mine workers' safety behaviors simulation system through combines virtual reality and mining safety production. The aim is to standardize safety behavior, improve the effectiveness of safety training and accordingly reduce the accidents' occurrence in coal mine. The system is constructed by means of LAMP building software. Then, an integrated development in the platform Virtools...
Most existing researches on Coalmine Virtual Environment (CMVE) are mainly concentrated on the geometric presentation or real-time dynamics to create immersive experiences in virtual environment and little attention has been paid on system modeling methodology and formal specification of CMVE. Based on Multi-agent technology, a hierarchical architecture for CMVE was proposed, which consists of ??Hardware,...
Many researches have shown that over 80 percent of the accidents in coal mines may be caused due to human unsafe behavior. One of the main contributing factors to unsafe behavior of miners was operation technique, i.e. their incorrect operation and peccancy, which resulted in accidents. This article proposed a practicable solution to how we can make the miners operate expertly and correctly and check...
This paper discussed the application of virtual reality technology and its application on prevention of coal and gas outburst in coal mine. With the help of virtual reality technology, the vivid and process of coal and gas outburst in coal mine could be obtained. The application of virtual reality technology on prevention of coal and gas outburst included development such as system requirements, data...
In order to construct digital coal mine, a three layer model for digital coal mine model is proposed in this paper. Two basic platforms, the uniform transmission network platform and the uniform data warehouse platform, are discussed. A real 1000 M industrial Ethernet transmission platform based on Siemens PROFINET is established for Yangchangwan coal mine. The network platform is an information superhighway...
