| Abstract: | In the mineral exploration of Zijinshan gold-copper mine, air reverse circulation continuous sampling drilling technology was used to solve the problems of the broken formation drilling, the difficult sampling in water-deficient area and the high construction cost. This thesis introduces machines matching, drilling process and attentions of construction; especially in broken and leakage formation of Zijinshan gold-copper mine, normal and reverse circulation DTH drilling were used to improve drilling efficiency, high sampling rate is received with improved construction efficiency and reduced cost. |
