P. M. Golubev is a co-author of more than 60 projects on determining the safe level for flooding coal mining enterprises, the main spheres of his scientific activity include:
- research into the processes of rock mass deformation and into the mechanisms of the deforming rock mass influence on the change in the soil surface relief;
- research into the rock mass and soil surface displacement in the course of undermining the soil surface and flooding coal mines, modeling of geomechanical processes in the multiply undermined rock mass;
- research into the influence of the physical and mechanical properties of rocks on the parameters of the soil surface displacement.
General information
At present, the Department is conducting the research work Research into the Deformed State and Geophysical Properties of an Undermined Coal-Rock Mass. The underground coalface operations at coal mines in case of strata control by complete cave-in result into the subsidence of the rock mass and deformation of the soil surface. The vast majority of cities and towns have been multiply undermined with stope ores. This has a negative impact on the objects of social and industrial infrastructure located at the undermined territories, and results into their being damaged up to their losing their functional state. The distribution of deformation zones within the rock mass is not stipulated by the effective normative documents, and the mine surveying observations in some cases record significant deviations of the actual surface deformations from the design ones, which can lead to unpredictable consequences, and result into the mine workings influence zones to cover the industrial enterprises and socially important objects that are not subject to undermining. An accurate prediction of the rock mass and soil surface displacements and deformations in the result of underground mining is required to prevent damage to surface objects caused by harmful effects of underground mining. One of the promising approaches to improve the accuracy of such predictions is the usage of exploration geophysics methods to establish the patterns of changes in the mining, geological and physical parameters of the rock mass at the undermined territories. Such research will form the basis for predicting geodynamic phenomena in coal mines, will allow specifying the undermined rock mass deformation zones, the locations of gas and groundwater accumulation therein, which will make it possible to determine the areas of methane flow entering the soil surface, to elaborate the adjusted criteria for predicting soil surface deformations and to enhance the safety in undermining buildings and structures.
The spheres of scientific and applied research of the Department are
- determination of the geological and geophysical criteria for predicting the state of the rock mass in the course of coal deposits extraction by underground mining;
- rectification of the undermined coal-rock mass parameters;
- rectification of the undermined coal-rock mass caviation parameters by the distance from the stope ore;
- determination of the patterns of changes in the geophysical properties of the rock mass within different sections of the displacement trough;
- research into the geophysical properties of an undermined coal-rock mass;
- modeling of geophysical processes in the undermined rock masses.
