Latest Patents
One of Dai-Shik Choi's latest patents is titled "Selective mining from horizontal holes." This method involves mining high-grade ore from an ore body using a near-horizontal hole. The horizontal hole is bored into the ore body through as many high-grade portions as possible. A jet mining tool is inserted into the hole to access the high-grade portion farthest from the tool insertion location, allowing for the removal of that portion of ore. The tool is then pulled out until it reaches another adjacent high-grade portion, which is subsequently jet mined. This process is repeated until all high-grade portions of the ore body have been mined, with the mined material being removed through the horizontally bored hole.
Another significant patent by Choi is the "Method of determining mine roof stability." This method and apparatus utilize the natural vibration frequency of seated roof bolts and/or roof structures to provide indications of bolt tension and roof stability. This innovative approach can enhance safety measures in mining operations by ensuring the stability of mine roofs.
