Abstract:

We introduce the basic properties of SQ114/8 hydraulic power tongs，and its application effects in Zhaishang core drilling in mining geology.Compared with the traditional manual unloading twist drill，the set of the introduction and application of power tongs can greatly improve the efficiency of the drilling and enhance the safety factor of labor，reduce labor intensity.SQ114/8 hydraulic power tongs drilled in the rock gold mining has played a huge role，made a very good application effects.Meanwhile，in practical applications，there are some problems for SQ114/8 hydraulic power tongs，such as kava tablets easy to wear，do not shift quickly，and drill pipe butt is not ideal.Through analyzing and summarizing the practical application and deal with the problems made some improvements to the promotion and application of construction equipment in the mine.

Key words: hydraulic power tongs, manual unboading twist drill, geological drilling, penetration rate
