YANG Xue
Abstract：In checking borehole constructions of a mine main shaft and mine auxiliary shaft in No .1 Mine of Tashidian Mining Area ,Xinjiang Xingmei Mining Corporation Limited ,a double-tube corer and TD2000/600 model top drive drilling machine were selected and matched applied ,the coring opera-tion was safety and high efficiently completed and the coring rate of the full borehole was about 90% . The coring achievements provided reliable basis for the preparation of the geological information .The paper emphasized the introduction on the structure features and technical parameters of the double-tube corer and TD2000/600 mode top drive drilling machine as well as the matched application condi-tion of the equipments .
