| Abstract | ||||
| Ordinary Kriging (OK) and Indicator Kriging (IK) techniques were used in conjunction with Geographic Information System (GIS) to understand the spatial distribution and variation of the P2O5% and phosphate thickness at Hagraria district, Egypt. The aim is to aid mining engineers in identifying the best areas that have high and low values of P2O5% with their associated thickness in order to manage the extraction scheme. This paper illustrates how the kriging results can be interpreted easily when they are integrated with other geological and mining data using suitable Geographic Information System. Both OK and IK were examined with the available data from the study area to estimate the two variables affecting the quantity and quality of phosphate; Additional information such as geological feature, boundaries of the area and sampling locations were integrated with the Kriging results and a GIS software (ARC/GIS 9.0) has been used to create contour and sensitivity maps that delineate the relative magnitudes of the measurements recorded at the study area, so a better management of the phosphate extraction could be planned. | ||||
