【 摘 要 】

In the article the problem of the quantitative estimation of coal deposit efficient detailed prospecting and a way of its decision which is based on the three sequential problems solving is considered. The quantitative assessment of performance itself is verified on sufficiency of the studies carried out by well-drilling. The sufficiency condition is determined by comparing the existing testing density with the predictive optimal one. The forecast of the optimum density of the testing network is based on the use of summarized relative entropy value, as measures of homogeneous significant mineable coal seams and also regulations acting on the territory of the Russian Federation. The application of the technique proposed in this article is considered on the sample of the Site No. 1 of the Elga Coal Deposit. The forecast of the optimal testing density, which makes it possible to increase the efficiency of acceptable design operational decisions for this deposit field was performed for following parameters of coal quality as raw-coal ash, thickness of the plastic layer, devolatilization and moisture of analysis sample. Due to the evaluation findings of the efficient detailed prospecting at Site No. 1 of the Elga Deposit it was determined that the existing network of exploration wells in the southern part of the site should be partially condensed.
