Sampling & equipment selection
Start with the sample your project needs, then consider the rig and tooling. Core drilling and reverse circulation produce different sample types, and equipment must be assessed against formations and site conditions.
Recovers core samples
Core rigs work with wireline core tooling. Selection depends on core size, target depth, hole angle and formation. Drilling depth capability varies with the selected core size.
Collects cuttings samples
RC rigs use drill rods, hammers and bits to collect cuttings through the return passage. Selection depends on depth, hole diameter and air supply. Hammer and bit compatibility also needs to be checked by model.
Field operations depend on moving equipment and supplies as well as drilling and sampling. Lifting and transfer arrangements need to suit site access, unloading space and the work that follows.
Changkun's West African field experience includes gold, bauxite and other mineral exploration. The mineral provides project context, while equipment selection still depends on sample requirements, formations and depth. Existing hole designs, formation descriptions or equipment lists can be included with your enquiry.
