Why Wireline Core Drilling Improves Mining Exploration Efficiency?
For mining exploration teams, drilling efficiency directly affects the entire exploration cycle and project cost. Traditional core drilling methods require lifting the entire drill pipe every time you take a core sample, which takes a lot of time and labor. Wireline core drilling technology solves this problem perfectly.
Wireline coring means you don’t need to lift the entire drill pipe out of the hole when taking core samples. You only need to lower a fishing tool into the drill pipe through a steel wire rope, pull the inner pipe with the core sample out, and then put the inner pipe back to continue drilling. This technology brings three core improvements to mining exploration:
Greatly improve drilling efficiency
You don’t have to spend hours lifting and lowering the drill pipe every time you take a core. You can complete the coring work in tens of minutes, which can increase the overall drilling efficiency by 30-50% and shorten the exploration cycle significantly.
Higher core recovery rate
Wireline coring causes less disturbance to the core sample during the extraction process. You can get more complete, less polluted core samples, which provide more accurate data for subsequent mineral reserve assessment.
Lower labor and equipment wear costs
Frequent lifting and lowering of drill pipes will not only increase labor intensity but also accelerate the wear of drill pipes and drill bits. Wireline coring reduces the number of drill pipe lifting operations, which greatly reduces labor costs and extends the service life of drilling tools.
