Reference: pre-collar hole Reference information: http://www.ithmines.com/_resources/pdfs/ITH-NR11-05-results-... A “pre-collar” hole is one that is started with reverse-circulation drilling and then converted to core drilling when the reverse-circulation drill reaches its limit (in this case, at approximately 300 – 350 metres). -------------------------------------------------- Note added at 2 days21 hrs (2012-11-23 12:11:29 GMT) -------------------------------------------------- “Pre-collar” hole je bušotina koja se izvodi prvo metodom bušenja sa reverznom cirkulacijom (reverse-circulation drilling) do maksimalne dubine koju ova metoda omogućava (300 – 350 m) a zatim se prelazi na jezgrovanje (core drilling). |
