Air Compressor and DTH Hammer Equipment

Product Code: BDAH
Equipment to enable pneumatic Down-the-hole Hammer drilling with the BDR/3 Drilling rig. With this equipment the driller will be able to work in all ground conditions and overcome almost all situations encountered.

NOTE: The kit is a selection of components suitable as start-up equipment for a new drilling operation and should be seen as a guide. Oxfam has a long association with the supplier and will work to design a drilling package that is most suitable to each programme and project location.

The Atlas Copco XAHS-186 compressor is selected to be compatible with the PAT 301T drilling rig and this down-the-hole hammer equipment. It is a robust, reliable, diesel powered unit and can be towed by most 4WD pick-up trucks.

Down-the-hole Hammer is also know as Percussion Rotary Air Blast (RAB) drilling. It is a technique that is used to drill boreholes in hard rock formations (such as igneous rock, limestone, sandstone etc). The hammer is driven pneumatically, forcing the button bit to break up the rock. Cuttings and debris are blown up the outside of the drill rods to the surface using air or air and foam.

Drilling may combine both rotary and down-the-hole Hammer techniques at the same borehole. For example: to drill through a hard overlying layer to reach a confined aquifer, or to drill in zones where bedrock is weathered to varying degrees.​​​​​​​
