Problems in Diamond Drilling in “Slipping” Formation of a Gold Mine and the Countermeasures

Abstract:

By the drilling construction in “slipping” formation of Laowan gold mine, the paper introduced the experimental production and laboratory test on diamond bit optimizing selection, summed up the drilling problems encountered in “slipping” formation and the corresponding technical measures.

Key words:diamond drilling; “slipping” formation; impregnated diamond bit; bit optimizing selection
