DEVELOPMENT OF CONCEPT OF METHOD OF ACCELERATED EXPERIMENTS TO FIND A GROUTING COMPOSITION MIXES FOR BUILDING WELLS IN PERMAFROST



Construction of wells diamondiferous deposits in Yakutia are many challenges. Due to complicated climatic and geological conditions are often complications arise, entailing an accident, the elimination of which requires the growth of material and time costs. The proposed method of process optimization experiments on the formation of mixtures to minimize the risks of complications of the above, first of all – by creating reliable plugging mixtures for lining wells.
