Uncovering Clean Air
Underground rock mining refers to various underground mining techniques used to excavate minerals from rocks. This includes either hard minerals, such as ore containing gold, silver, iron, copper, and lead, or softer minerals, such as salt or coal. Coal is a key source of energy and is a natural resource found all around the world. Approximately 60% of world coal production currently comes from underground mining.
Mining underground comes with its own unique set of challenges. One of the most important aspects of underground mining is ventilation. Ventilation is the primary method of clearing hazardous gases and dust which are created from drilling, blasting activity, and gases that are naturally released from the rock.
An underground mining operator came to AAF® for a solution to reduce the dust being pulled through the main mine ventilation fans. AAF® recommended the RotoClone® N due to its relatively small size compared to a traditional baghouse. Additionally, this wet dust collector has the ability to handle hot, moist gas streams and explosive dusts with no moving parts. The RotoClone® N cleans the air by the combined action of centrifugal force and a thorough intermixing of water and coal dust-laden air.
