How To Use A Compressed Air Or Nitrogen Drilling Machine

Air drilling or also called pneumatic vibration drilling is an underpowered drilling technique in which compressed nitrogen or oxygen is used to manipulate the bore hole and elevate the cuttings in place of conventionally utilized liquids. Known for its efficiency and affordability, air drilling continues to have doubters and critics, even though its long history in the mining and petroleum exploration industries proves its reliability and hence it continues to be utilised to this date. One of the problems that drilling rigs face is the contamination of the drilling ground by drilling fluids. This contaminated soil may contaminate the borehole as well, hence it is very important to keep the drilling fluid clean while drilling. If not cleaned, the drilling work can become a total nightmare.

The mist and dust caused by air drilling work can severely affect the working conditions. Due to the nature of the drilling operation, spills of air drilling fluids are inevitable. The spills have been categorized into wet oil spills and mist spills. Wet oil spills occur when the air drilling fluid seeps into the underground rock and causes the natural fractures leading to water influx. On the other hand, mist spills occur due to poor spill containment, human error, or equipment malfunction.

Some of the factors that affect the air drilling fluids include, but are not limited to, temperature, proximity to the surface, humidity, sunlight, wind, and rain. If temperature is high, mist tends to form because the viscosity of the oil will be less, thereby allowing a faster and easier conveyance of the air into the borehole. However, during summer, it is recommended to allow air to flow freely inside the borehole so that there will be sufficient moisture to avoid the formation of clouds. It is also advised that a worker should wear a face mask to prevent the inhalation of fumes from compressed air.

During rainy days and nights, dust may also accumulate in the borehole, which may affect the quality and efficiency of the operation. This is attributed to the build-up of mud and debris in the borehole, combined with condensation. To address this issue, workers should put on face masks, take off their shirts, and fill water cans or containers with enough water so as to avoid the accumulation of mud and debris.

There are different types of compressed air, such as nitrogen, oxygen, and pneumatic. Nitrogen is the most commonly used because it gives the best results when used in conjunction with mechanical sealants. Nitrogen is a highly flammable gas and should therefore be used in accordance with the rules and safety measures stipulated in the Operating Procedures. When choosing a compressed air source, make sure you select one that does not contain ammonia or chlorine. Both of these are known to cause serious health hazards.

Dust drilling is a popular method employed in many excavation projects. When dust drilling occurs, some of the workers may become dust covered in the process. This can increase the risk of having the eyes, nose, and throat contaminated with dirt and dust. It can also affect the working environment, and workers should wear goggles, masks, and gloves to protect their bodies from this airborne contamination.

It is essential to keep a stash of compressed air, dust collecting materials, at work. Workers should make sure they know where to find these supplies, and they should practice frequent collection of waste for every drill bit. A bucket containing compressed air should be kept next to the air drilling machine. You should ensure that the bucket is kept dry at all times. Also, ensure that the compressed air cylinder does not get overheated and never leave the cylinder near an open flame, lighted candles, or any other source of ignition.

You can use the various types of dust and air systems for the various kinds of tasks associated with aeration, mist drilling, and nitrogen. There are several options available in the market, based on the requirements of your project. You should choose the one that will provide the best results for the job, while being environmental friendly. Air and Nitrogen Drilling are some of the best ways to keep your site looking clean and ready for business.
