Optimum sampling density for the prediction of acid mine drainage in an underground sulphide mine

Summarization: Information theory allows one to define an optimal sampling density. Sampling above this critical frequency adds very little accuracy to the mapping results. We demonstrate the establishment of a critical sampling grid for the Stratonion mixed sulphide mining area in Chalkidiki peninsula, Greece, and the extraction of maximum information; the data used was derived from a previous sampling campaign carried out to estimate ore reserves and predict the net neutralization potential (NNP) of the rock formations. A structural analysis of NNP values generates a variogram model that can be used to define the optimum sampling grid.Παρουσιάστηκε στο: International Mine Water Association Symposiu
