Aircore drilling is used extensively for first pass exploration. It is the preferred drilling method for drilling top soil formations. Soil rocks up to a certain depth can be removed using this technique. It does not require the use of heavy machinery as is the case with other earth drilling methods. Different designs of tungsten carbide drill bits are used in this process. The drill bit is attached to the front of a drill rod that is inside a hollow metal tube. The inner space of the tube is used to take out loosened materials. The samples are separated and extracted from the materials during the same drilling process.

It has emerged as the preferred drilling method to collect mineral samples without damaging the specimen. It is different from the rotary air blast and other drilling methods. Mineral exploration companies now prefer this technique over traditional drilling methods. It is an efficient way to extract the samples quickly and easily.

How Does Aircore Drilling Work?

The air is compressed and applied at extreme pressure into the hole. It blasts up the material which can be then removed easily. It is a simple mechanism that delivers effective results to take out the required underground samples. The whole process is error-free and effortless. The equipment used for this purpose completes the task on its own and does not require much manual intervention.

Preferred Drilling Method for Productive Mining

The mining industry has been progressing rapidly. The advent of air core drilling is a major reason behind this rapid development. This drilling technique has proved its effectiveness in drilling the ground up to a depth of 300 meters. Mineral exploration companies have been using it to extract rich minerals in a quick time. There is no need to worry about material contamination. That problem existed with traditional drilling methods. The Aircore method of drilling delivers contaminant-free minerals. The sample is collected quickly with minimum damage.

Advantages

There are several benefits of this drilling method. The collected samples accurately represent the minerals present under the ground. This type of sample is easy to analyze because there is no contamination. There is no need to case the hole. Deep drilling makes it easier to collect the minerals from hard to reach depths. Minerals found up to 300 meters can be extracted with this easy, quick and economical drilling method.

Aircore drilling offers many advantages over other drilling methods in certain mining exploration projects. The equipment used for this purpose is easy to operate and lightweight. The whole drilling equipment can be put on a vehicle and taken to most locations easily.
