Abstract

Abstract

The gold orebody shows cylindrical output with small section area in Jinchang mining area of Heilongjiang Prov-ince, the location deviation is common for the densive borehole distribution.The directional drilling technology is introduced to control the drilling trajectory, which improves drilling efficiency and develops branch holes to learn the morphology of ore body.The paper introduces some affecting elements and the technical measures in the application of directional drilling.
