Blast Hole Drilling

At WR Drilling the rigs used for blast hole drilling are set up specifically for the use of high benches in open cast mines. The drilling pattern depends completely on the client’s needs and parameters. The diameter of the blast hole is the most important aspect to consider. The size of the blasthole diameter can determine the long term outcome of the mining project. The type of rock, the fragmentation of the rock and the type of work that needs to be done all play important roles in the blasthole drilling project. 

Symmetrix drilling

Symmetrix Drilling

Symmetrix and or better known as overburden drilling system are of our specialities.
Symmetrix work is undertaken in unconsolidated and unstable top formations. Symmetrix up to a diameter of 273 mm are undertaken.

Reverse-Circulation Drilling

Reverse circulation drilling is similar to air core drilling as the samples that are drilled up from the earth are not simply placed onto the surface surrounding the machine but the samples are instead shot up into the hollow pipe of the machine. This is one of the biggest benefits of the reverse circulation drilling procedure because it prevents the samples from being contaminated from other materials that it might come into contact with once it has been removed from the earth.

The reverse circulation drilling method has the capability of reaching depths of 500 meters.  A pneumatic hammer-like device is used to hammer into the earth to remove rock samples which are then pushed up into the mining machine using compressed air. The samples are collected in a sample bag which is located within the machine. More than one sample bag can be collected which allows for more of a variety of samples to be analysed. Sample bags are usually marked to show the location from which the sample was taken as well as the depth from which the samples are extracted.
