IMPROVEMENT OF THE TECHNOLOGY OF DEVELOPMENT OF RESERVES OF THE EMISSION-HAZARDOUS FORMATION OF THE КРII STRATUM IN THE CONDITIONS OF THE EUROCHEM USOLSKIY POTASH MINE

Abstract

This article presents the results of the authors' research on the construction of a pre-diction map with the division of an explosive potassium formation of the KPII stratum into haz-ardous and non-hazardous areas in the conditions of the mine field of the EuroChem Usolskiy potash mine, it is discovered that the decision rules developed for the other potash mines of the Verkhnekamskoye potash deposit are fundamentally unsuitable for the site concerned and re-quire revision, options of improvement the decision rule are proposed. Recommendations for safe mining operations, implicating a change of the existing mining technology, are presented at the end of the article.
