Intelligent coal mine target location service technology based on big data and AI driven

Dirven by big data and artificial intelligence,the locations of mine objects and events can provide abundant services which are far beyond the scope of single system,such as personnel localization,equipment orientation determination,robot navigation and unmanned driving,so it is better to design the mine location services from the perspective of systematic and global view. This paper proposes the framework of mine location service composed of four layers,i.e. location object layer,location acquisition layer,location transmission layer,location excavation and service layer. The three key technologies are discussed. The precise localization technology of moving objects in mines focuses on the distance measuring,measuring optimization,object location computation and localization system development. The location big data of mines studies the collection,storing and analysis of big data. The artificial intelligence algorithms for mine location services mainly consider the perception intelligence,production intelligence and decision-making intelligence. Then the hot research areas are surveyed,including the emergency evacuation and rescue,remote mining and unmanned mining,mine location service applications. These hot areas mainly include the following fields:optimization of escape path,determination locations of trapped workers and making rescue,cause analysis and responsibility definition of accidents,localization,orientation and navigation of mining devices,cooperative localization and navigation among multiple robots,unmanned driving technologies and equipment for coal mines,accident time-space evolution laws,scheduling and decision-making based on trajectories,“one map” in production process of coal mines. The mine location service is becoming an infrastructure of coal mines,and its future directions are the ubiquitous network with space-time properties,decision-making model library with location reasoning and intelligent mine platform with location services.
