On methods of determining the density of the exploration network

Abstract

The importance of the correct solution of the question of rational density of the exploration network does not require explanation. The literature devoted to it is extensive and is continuously being replenished. They are most clearly formulated in a general form by V. I. Smirnov [1957]. Many methods of calculating the necessary and sufficient number of exploration workings have been proposed and they continue to be developed. Usually the proposal of a new method is accompanied by a mention of previously proposed methods. But in the literature there is very rarely found a systematic and comparative consideration of at least the best-known methods of determining the rational density of the exploration network with respect to one and the same specific object. No one seems to object to the general statement that all methods of calculating the density of the exploration network are auxiliary to the geological method, but what this means exactly - nowhere and no one clearly shown. Not surprisingly, there is no complete agreement even on the way to solve the problem. Usually, the producers determine the network density according to the tradition accepted at each field. If they take the path of theoretical calculations, they use several methods. The decision is made on the basis of sufficient convergence of the results of such calculations. At the same time, they are often given dogmatic value without proper geological analysis. Meanwhile, they can sometimes lead to errors and miscalculations. This article does not offer new ways to determine the density of the exploration network. By comparing a number of known methods in the conditions of a particular object, we are trying to establish the true value of each and the general way of solving the problem. It would be desirable to receive specific comments and suggestions on the question raised, in order to arrive finally at a generally accepted optimum solution of it ...
