Increasing validity of geoinformation support in mining waste management

Distribution of useful component in mining waste depends on dirt rock portion to be dumped, sequence of layering and unpredictable segregation in cluster zones by fraction composition and content of the useful component. It is of the prime importance to learn to predict quality characteristics in the whole volume of a man-made mineral deposit using discrete data from separate sampling points. Validity of the results depends on distribution of useful component in a natural deposit, exploration pattern parameters assumed in the man-made deposit survey, volume and geometry of samples as well as on technological factors. An efficient approach to the analysis of properties of a geological object is using geostatistics, which, with additional characteristics involved, allows identifying regular and random components of variability and predicting internal structure by means of detection of autocorrelations between separate samples in the preset directions. The algorithm is developed and validated for modeling distribution of useful component in a man-made deposit, including geometry of sampling arrangement, regular mesh parameters, correlation interval of geodata in each preset profile, number of geological samples in the connectivity interval and root-mean-square error per profile, to form a blocky model of a man-made deposit.
