Product Description

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.

Advantages

1. Although the process can be costly the overall drilling costs can actually be reduced by up to 40% when using reverse circulation drilling.

2. Results from reverse circulation drilling can be revealed much faster as the completion of the drilling process is done quickly.

3. The method is safe to use and requires fewer man hours.

4. Reverse circulation drilling requires less water than other mining methods.

5. Reverse circulation drilling is simple and easy.

6. Samples can be easily arranged into boxes stating where the sample was collected and at what depth the sample was collected which will help those studying the samples to pinpoint exactly where the mineral deposit is located. This will help a mining company or a group of researchers to quickly and easily locate the exact area and depth from which the sample was discovered.
