摘      要：Resource modeling plays a crucial role in raw material quality management for cement *** has shown that geological uncertainty in resource modeling is inevitable and results in risk to future extraction planning and operations of the cement *** study aims to assess the geological uncertainty and associated risk in modeling a cement raw material deposit in southern *** this deposit,soil,clay,laterite,and limestone are the four primary rock types,controlling the occurrence and spatial distribution of chemical *** this study,hierarchical simulation method was used to evaluate the *** types were first simulated,and the chemical grades conditioning to the rock types were then *** results demonstrated the capability of the hierarchical simulation approach to incorporate the uncertainty of rock types in resource modeling and to allow evaluating the risks in providing the desired raw material for the cement plant in the form of grade-tonnage curves.
