METHOD FOR EXTRACTING ROCK MATERIAL UNDERGROUND AND FULL FACE BORING MACHINE

摘要

The invention relates to a method for extracting rock material underground by forming a drift, and a full face boring machine provided for this purpose, comprising a rotatably driven cutting head which has a drill diameter that predefines the diameter of the drift. According to the invention, by means of the full face boring machine, a first drift is started and formed in a first drift direction emanating from a first main path to a second main path, the full face boring machine is turned around in the second main path, and by means of the full face boring machine a second drift is advanced and formed emanating from the second main path in a second drift direction which is substantially opposite to the first drift direction, which second drift extends along the first main path at a distance.
