“…Investigation of DS promotes a better understanding of the deep mechanism and facilitates more effective control of the complex irreversible processes. In this paper, we consider such processes as landslides [3], sinkholes, and ground movement due to underground mining [4], which expose the environment to the big hazards but effective control of which is far from excellence. A distinctive feature of these processes is that DSs are hidden and it is not easy to reveal them confidently.…”

The dissipative structure (DS) may follow irreversible processes, which occur in the open thermodynamic systems passing and transforming a sufficiently intensive flow of energy. DS can be detected as certain patterns of spontaneous organization in space and time. We consider the DS, which transposes during irreversible ground movement due to landslide or ground pressure manifestation. However, DSs may hide under stochastic noise that impedes their detection. We developed a new method for revealing of DSs in such a stochastic environment using a combination of k-mean clustering, Voronyi tessellation, and the optimal schedule of ground movement monitoring. The developed method has been successfully tested in the case of the irreversible ground movement in the vicinity of a longwall face.

“…As far as we know, DS has not been revealed during irreversible movement of the ground so far. Recently, DSs were detected for the first time during instrumental observation of a slow landslide development [3] and microseismicity monitoring of the hydrofracturing process [4].…”
