Abstract


This convergence of the system from the extractive daily production work in the mines of the importance of , and expounds on the current rapid development of information technology to improve and perfect the system , making it more in line with the current needs of the mine the significance of the actual production . In the design of the overall structure of the system , the combination of geographic information systems, computer technology advances and geographic information systems in the coal mine production and development in the field of application of the actual situation, put forward convergence of GIS-based decision support system for mine excavation and development of new ideas, of the system development method of choice , and the system into functional structure . Since the mine geological objects involved in the production of the complexity and uncertainty of article focuses convergence of mine mining geological objects involved in the system 's basic features , proposed for the description of the mine geological objects object-oriented data models and data structures. Convergence in extractive analog control mode selection, through a comparative analysis to determine the appropriate minimum time mine complex nature of the event step method of simulation methods , and through analysis of convergence are involved in mining the basic entity mining teams, excavation teams, coalface and tunneling face features, built simulation models . Timing convergence test in the extractive model , using time series analysis methods to predict the daily production and face the daily footage heading face , face and heading face to predict completion date in order to test mining convergence results. Finally, in Beijing Long Soft company develops lrGIS3.0 platform to achieve the convergence of the original data mining inputs and outputs heading face convergence report , and in the actual production in the applications. In summary , the paper design of GIS-based decision support system for mine excavation convergence meet the needs of the actual production of the mine , the mine excavation convergence work to reduce costs , improve work efficiency has important theoretical and practical significance .
