Application of portable full hydraulic drill in geological drilling in Qinling area
Abstract:This article introduces the application of portable full hydraulic drilling rig in the geological drilling of solid mineral drilling in Qinling area, and briefly describes the basic situation and drilling process of EP600 series drilling rig, and analyzes the relationship between rock drillability and drilling efficiency in combination with 11 holes in different work areas. For the issues in terms of the drilling rig in the drilling efficiency,power loss, construction ability and the like , good tests’ results have been initially achieved by the reasonable selection (improvement) of the drill bit, the reduction of the internal friction resistance within the drill pipe hole, and the adoption of light high-strength drill pipes and other effective measures or suggestions. The applicable conditions and advantages of a portable full hydraulic drilling rig are proposed,the drilling rig has high drilling efficiency in shallow holes (hole depth less than 350 m) below rock drillability level Ⅶ, and has convenient relocation, fast assembly, and less environmental damage in complex terrain environments, and meets the relative requirements of the ecological environment protection policy and green exploration work, and the overall economic cost of drilling is significantly reduced. For the unresolved problems, reasonable work suggestions are given, which play a positive guidance and reference significance for better exerting the efficiency of portable full hydraulic drilling rig in next step.
