Abstract:
In order to improve the automation and intelligence of longwall mining,according to the automation and intelligent trend of longwall mining,and in view of the problems that the information of the mining area in the construction process of some intelligent coal mining enterprises is unknown,and the production process decision is not enough objective,this paper briefly introduces the concept of transparent working surface based on new technologies such as internet of things and virtual reality and four aspects of technology architectures of transparent longwall mining face and the significance of its construction.Based on the analysis of the special requirements of automated mining of coal mining enterprises,a four-aspect global model of transparent longwall face construction is proposed.The architecture of entire transparent longwall face is designed from four levels: intelligent application,information,transport and sensing.The whole domain model for transparent longwall face and the key technologies required in the construction process such as laser scanning,geological exploration,inertial navigation,device condition sensing,vrtual reality,are described in detail.Finally,the status quo and challenges of the development of high-level intelligent applications in the perception of technical bottlenecks in the construction of transparent working surface are summarized.The result shows that the transparent longwall face model based on internet of things and virtual reality technologies architecture has certain guiding significance and reference value for the automation and intelligence construction of coal longwall mining.
