【Abstract】 A radius basis function(RBF) networkbased model su itable for reconstructing the geological surface was established, and its algorithm prese nted in detail. Compared with the common methods of interpolation, the RBF network mode l has no special requirements for original data and boundary con ditions. Therefore, it is es pecially suitable for reconstructing the geological surface which explora tion data are not enough or destroyed in some degree. Compared with the traditional BP network, the RBF network model is fast in convergence, thus is valuable in practice. The results of applicatio n of this model to the reconstructon of coalbed surface agree well with the actual situation.更多还原
