Shotcrete drilling with a solid bottom hole
Authors:
Abstract
When exploring mineral deposits, drilling with a solid bottom hole, i.e. without coring, is being used more and more widely. Coreless drilling makes it possible to increase productivity by increasing the mechanical speed of drilling, reducing the time for downhole operations, eliminating the time spent on coring, simplifying drilling technology and, accordingly, reduces the cost per linear meter of drilling.
