Popis: The calculation model for the basic parameters of a tunnelling machine with a working organ of a bypassing type is developed based on the experimental data obtained. The specifications of machines for making holes with a diameter of 325–426 mm by a combined method are substantiated. The test data for a tunnelling machine prototype are reported.
