Rotary Drilling Technical Summary
Supplying air at the correct volume and pressure is critical for optimal bit performance. To ensure effective hole cleaning, a minimum bailing velocity of 5,000-7,000 feet per minute is recommended for dry cuttings, and 7,000-10,000 feet per minute for denser or wet cuttings.

Editorial
Thomas opined in 2012 that reverse circulation (RC) drilling has become standard practice in most mines across the world. First developed in Australia in the 1970s, the drilling technique was originally conceived as a solution to the drilling difficulties encountered when using open hole techniques in soft iron ore and mineral sands.
