Abstract: Kriging algorithm is a method for estimating geological features in a certain area. However, this kind of estimation is not an intelligent one. Thus, the result cannot show the heterogeneous characteristics of the estimated area. To solve the problem, the authors put forward the Expert Kriging Interpolation Method, which applies experts' geological knowledge in kriging interpolation, so that the result meets actual geological conditions. The theories and models of the Expert Kriging are described in detail. The effectiveness of such method is verified by case study.
