Abstract:
The article presents the problems of developing mineral deposits under or near water bodies, as well as the results of the analysis of a multi-year data array of monitoring deformation data of rock mass, including those located in the Donetsk coal basin. Examples of coal mine flooding with a recorded manifestation of discontinuous water flow rate are considered, when intervals of maximum flow rate were replaced by intervals of multiple weakening of the inflow, as well as an uneven rise of mine flooding. The results obtained showed that in order to ensure safe development of subsoil near water bodies, it is necessary to take into account the factor of the hierarchical state of natural cracks in the rock mass, as well as the fact that water, especially under high pressure, is a significant factor influencing the change in the crack system of the underworked mass.
