| Abstract:Greenstone belt golden ore prospecting project at Victoria Lake in Tanzania consisited of seven boreholes and a total of 2500 meters of drilling. In fact, twelve boreholes were completed and a total of 3201.2m meters of drilling were realized. It created our record of maximum drilling meters and drilling production in five months using one drill rig. The paper introduces drilling technologies used on this district from the aspects of geographic and geological overview, drilling equipments, drilling technologies, drill bit, drilling mud and main economic indicators. It may offer guidance for drilling in similar districts. |
