Abstract

THE APPLICATION OF NONPARAMETRIC GEOSTATISTICS IN ESTIMATION OF MINERAL DEPOSITS PARAMETERS - EXAMPLE FROM A SELECTED COPPER DEPOSIT OF THE LUBIN COPPER DISTRICT, POLANDAbstract. Two methods of nonparametric geostatistics: indicator and probability kriging were presented as alternatives to classic kriging and to traditional, polygonal method of reserves estimation. Both proposed methods were tested in estimation of copper reserves for a fragment of deposit from the Lubin Copper District, Poland, basing upon data from exploratory wells. The estimation results were compared with those obtained with the traditional, polygonal method of reserves calculation. The advantages and disadvantages of applied methods were commented on. The results allowed recommendation of probability kriging as the most relevant method. Other applications of nonparametric geostatistics in the assessment of mineral deposits were presented, particularly for contouring of deposit parameters and for prediction of recoverable reserves.
