| Abstract:In the exploration of tertiary conglomerate gold, with the characteristics of shallow drilling hole, complex formation, high quality demand of coring, long distance from water and being hilly land, reverse circulation central sampling technique is taken in use. Different drilling parameters and technology was adopted for different formations with considerable technical result and economical benefit achieved. |
