“…In the periods in which the vibration generator is turned on, you can clearly see the acceleration of the drilling process and greater penetration of the rock. Additionally, there is an increase and decrease in the load measured by the force sensor, which proves the progress in drilling (i.e., rock drill ability) [8]. Having such promising results, it was decided to submit a grant application to the European Research Fund for Coal and Steel.…”

“…The torsional generator TG adds the torque T 2 on the drilling head which is loaded by the torque T 3 . The blocks denoted by PS MDM and PS TG in Figure 4 represent the power supply of the main driving motor MDM and torque converter TG; it can be a simple grid power source [1,2,8,9] or more sophisticated such as the PWM (pulse width modulated) inverter with the vector control algorithm [10][11][12][13][14][15][16]. The mathematical model of the squirrel cage motor, playing in our drilling rig the role of the main driving motor MDM, in terms of the ordinary differential equation is as follows [3,7]:…”

This article focuses on the possibility of using an innovative drilling method for the implementation of underground works, especially where there is no physical possibility of using large working machines. Work on a model carried out under the INDIRES project is discussed. A design of a drilling tool equipped with the proposed technology is presented. The solution in question makes it possible to increase the efficiency of the drilling process, which is confirmed by computer simulations. Also, introductory tests of a drilling process supported by torsional vibration generated by an electromagnetic torque generator provided in the KOMAG laboratory facility show the reduction of the drilling time by almost two-fold. In our opinion, adding torsional vibration acting on the plane of a drilled wall that equals natural frequencies of the drilled material represents a promising new technology for drilling. The presented work constitutes the basis for the development of the proposed technology and allows us to conclude that the developed method will be of great interest to manufacturers of drilling machines and devices.
