Evaluation of Invariant Characteristicsof Massif for Efficient Quarryingof Coal Pits

摘要

The authors represent the invariant analysis of geotechnological parameters of massif forrnefficient mining. Scientific researches prove invariant character of the phenomenon of naturernand natural structures. The knowing of this invariant interval is very important for increasingrnthe efficiency of mining of mineral deposits on the basis of better dissociation of the rocks.
