| Abstract: | A method for deposit resource estimation based on BP algorithm is proposed in this paper. The basic theory and algorithm steps are introduced.Based on the analogous research of the known metallogenic modes, through the partition and selection of cells of researching area, factors needed in the estimation are confirmed. The nonlinear map among variables and the estimation model is ascertained by studying the sample through BP algorithm, then the predicted cells were estimated and the estimation results were obtained. |
