H&F Drilling

Covering all sections of the drilling industry that require geological information to be gathered, whether it be for the design of foundations for a housing development, the foundations for a major bridge, the search for mineral resources or the determining of the suitability of stratas for the deposition of carbon dioxide and so on.

Often the drilling is accompanied by the installation of complex instrumentation, or in-hole testing which can provided an array of information essential to the successful outcome of major projects.

By it's very nature, Exploration Drilling, can utilise numerous drilling methods to achieve the required results and therefore it is of paramount importance that the most appropriate equipment is selected to optimise results.

We manufacture and supply a range of rotary coring barrels, soft ground testing and sampling equipment, as well tungsten carbide coring bits, temporary steel casing, plastic tubing for installations and a range of sealing products such as bentonite pellets.

Additionally, we also offer coring equipment from Atlas Copco Craelius and DATC of France, both metric and DCDMA formats.

As the exploration for mineral resources often involves large sums of speculative capital investment, the need to gain information quickly and cost effectively has meant the increasing use of Reverse Circulation (RC) drilling, both rotary and down the hole hammer methods.

RC drilling allows the rapid recovery of samples by the use of high pressure air, forcing the drill cuttings up through the centre of the drill string and collected at the surface through a cyclone. This method is substantially faster than traditional diamond core drilling and almost as effective in sample recovery. It is certainly increasing in popularity amongst mining companies and their consultants.

We can supply a range of RC drilling equipment from companies such as Metzke, Atlas Copco and from our in-house manufacturing.

So whatever your exploration project is for, give us a call to get the information and advice to help you make the correct decision and select the most cost effective method.
