Forecasting of the content of the insoluble residue in clay layers of productive beds of the Verkhnekamskoe salt deposit

Abstract

Using data from the exploration drilling at the mines BKPRU-2 and BKPRU-3 of JSC Uralkali, the relationship equations between the content of insoluble residue in the productive sylvinite beds and thick interbedded clay layers at their top referred to as «korjʼs» are worked out. Knowledge of composition and thickness of clay layers is very important for rockfall protection during mining work. The results of analysis of drilling data are often not reliable because of the losses of clay material in the extracted core. The resulting equations are recommended for forecastingof insoluble residue in «korjʼs» of those beds.
