THE SPATIAL INTERPOLATION METHOD EFFICIENCY EVALUATION OF THE COAL MINING ISOLINE BASED ON SURFER

Coal mining isoline map is commonly used in the coal resources exploitation.Traditional manual plotting is not only slow-rate and inefficient,but also quality-unguaranteed.The software-Surfer 8 can be used to select suitable interpolation method firstly to grid the separated data related to coal-mining,and then draw isoline,which can ensure the isoline mapping precision as well as efficiency and provide basis for management and guidance for mine production.
