Abstract (en)
[origin: US6591920B1] A fusion drilling process and device for the placement of dimensionally accurate borings, particularly those of large diameter, in rock, in which the waste melt is pressed into the surrounding rock, which is cracked due to the effect of temperature and pressure, and in which a borehole lining is produced by solidifying melting during boring, with a melt containing metal supplied through pipeline elements as a boring medium to the base of the borehole to be removed through melting. For this purpose a melt made of magnetic metal is preferably used.
