Application of Wire-Line Coring Hydraulic Hammer Drilling in a Deviated Gold Mine Formation

Article Preview

Abstract:

The wire-line coring hydraulic hammer drilling technique was used in the drilling process of gold mine of Henan province, which has solved the problems in a deviated formation. Based on the introduction of field situation, drilling equipments, drilling tool selection and performance parameters of wire-line coring hydraulic hammer, the main factors of hole deviation and prevented measures were discussed and also the deviation mitigation effect of this technology were analyzed and evaluated.
