Application of Kriging Interpolation Method in the 9201 Working Face of Dongyi Coal Mine
To solve the problem of transparency in the working face and analyze the characteristics of existing geological data,a three-dimensional geological modeling method using multi parameter Kriging interpolation is adopted to determine the modeling method and parameters suitable for Dongyi Coal Mine.The results show that:1)the coal seam as a whole presents a monoclinic structural feature of"northwest high,southeast low";2)As the number of nodes increases,the sum of squared residuals in Gaussian models shows a positive correlation with the number of nodes,while in spherical and exponential models,there is a certain negative correlation between the sum of squared residuals and the number of nodes;3)The rela-tionship between regional average and residual sum of squares shows three zones,with a negative correlation in the[150,1 000]range,a transition zone in the[1 000,1 250]range,and a positive correlation in the[1 250,1 600]range;4)The optimal parameters for Kriging interpolation are S=15,N=10-6,G=1 100,and exponential model.The Kriging interpolation method was used to construct a three-dimensional geological model,which visually represented the three-dimensional spatial undulating characteristics of coal seams,providing data support for coal mining face mining and intelligent construction.
