Abstract

This article gives the results of development and implementation of system of statistical methods of final control and quality assessment of loaded products at First – Forth Mining Department of «Belaruskali» JSC. This system includes the electronic folders of modified receiving charts of loaded contract batches by all standardized indicators. Usage of folders of receiving charts makes possible to do the following operations:
-on-line operative controlling of loaded products' quality;
-getting the complete visual information about each contract batch (both qualitative (according to all indicators) and quantitative (mass of loaded products));
-receiving of statistical parameters of qualitative indicators of loaded contract batches (average value, confidence interval, capability index, possible quantity of irregularities) in the process of unloading to consumers. Usage of receiving charts for controlling of products' loading and optimization of its quality is possible in prospect.
