Blind shaft drilling: The state of the art
This report discusses the ``Art`` of blind shaft drilling which has been in a continual state of evolution at the Nevada Test Site (NTS) since the start of underground testing in 1957. Emplacement holes for nuclear devices are still being drilled by the rotary drilling process, but almost all the hardware and systems have undergone many changes during the intervening years. Blind shaft drilling and tunnel construction technologies received increased emphasis with the signing of the LTBT in 1963.
