Study On Mine Geographical Information System For Mine Rescue Robots

Different from the former mine management system,the mine GIS system in this paper mainly faces the coal mine rescue robot. Firstly, it sets up spatial database of laneway and makes the inquiry between the graph and attribute come true; the establishment of model of the 3D visualization realizes the simulation of 3D and its management; finally the construction of the geometry network analysis model for laneway realizes the inquiry of the laneway and the optimal path analysis of the robot. The mine GIS system is mainly used as a guide in the mine rescue robot in the process of positioning, navigation and real-time route planning. This paper focuses on the following keys:(1) Construction of underground laneway spatial database: it makes muti-source data warehousing and muti-storey structure map that do zoom in or out and other basic functions come true. And it achieves data interactive enquiries between the graphs and attributes for real-time location. Based on the robots and real-time data acquisition, we can draw graphic elements such as points, lines, texts and others. The database is based on data of the laneway, and is loaded into industry square, shafts, mine border with the laneway closely related data as supplemental information for the underground laneway options for the provision of adequate data.(2) Model of laneway Geometric network analysis: It is the core of the mine GIS system, which builds the spatial database of underground laneway and established the geometric network in accordance with the flow chart. The focus is the design of the network structure which puts the network nodes as bifurcations and builds the network rules.(3) 3D visualization and analysis of model: It establishes the TIN surface for all levels of underground laneway according to lead elevations in the spatial database. Set in three-dimensional space in the roadway elevation benchmarks access to the selection of elements from the surface layers of elevation can be quickly set up a three-dimensional scene of roadway in 3D display.(4) Analysis and trace for Succor circuitry: the underground laneway is based on the geometric characteristics and attributes of the network, in view of the coal mine robot path planning positioning navigation conditions for the analysis and real-time rescue robot. It mainly involves rescue robot localization and related management information, and to achieve click on specific location information in the database has been called query and analysis, access to the scene of the accident scene and the location of the gas and dust concentration, temperature, humidity, and other parameters.
