Title: Realization and Application of 3D Reserves Estimation System Based on Geostatistics
Abstract: On the basis of the theories of geostatistics and 3D geological modeling,the authors propose a designing model of 3D reservoir estimation system,that is constructing 2D contour lines on the prospecting line sections of the mineral body on the basis of the original data and the edge grade at first,and then establishing the orebody solid model through the contour mosaic calculation method;thirdly,defining the block model and constraining it using the orebody solid model;after the creation of the 3D block model,applying kriging interpolation to interpolate space attribute of the geological body;finally,computing the reserve estimation.The key techniques used in this system are the arithmetic of varigram auto fitting,the contour mosaic calculation method and the OBB tree technique in constraining block model.The system has been conducted in a real mineral area,and the result agrees with the actual reserves of the mine.
