Some problems in control of the quality of the process of rotary drilling of rocks by using suitable visualization of concurrent vibrations

The process of separation of rock massif by rotary drilling belongs to the most frequently used geotechnologies. Since their energy costs are significant, it makes sense to pay sufficient consideration to the subject of efficient mode of drilling. Only an efficient drilling mode can guarantee the overall quality of this process. This contribution builds upon previous works of the authors in the area of utilization of abstract Hilbert spaces in control of specific processes. In this paper, some possibilities and aspects of visualization of concurrent vibrations in respect to efficient control of drilling are pointed out. In the contribution are processed some data obtained at the experimental drilling stand of the Slovak Academy of Sciences.
