The process of separation of a 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 an 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 with respect to efficient control of drilling are pointed out. The result of implementing the vibration signal as a vector in Hilbert space is the algorithm for recognition of the class into which the rock being separated belongs based on its geomechanical properties. The algorithm is based on geometrical interpretation of time or frequency characteristics of the concurrent vibrations. The method was applied to concurrent vibrations from drilling on an experimental stand and also from tunneling. The achieved results confirm the suitability of the proposed algorithm for its application in the system of automated setting of an efficient mode of drilling of rock massif. |
