“…Since a part of the receiving hopper and gallery No. 11 are located above the zones of decompaction, additional work has been carried out aimed at identifying and outlining these zones by geoelectric and radar control methods [10]. Analysis of the data of survey showed the need to perform measures to increase the load-bearing capacity of the soil base in the northeastern part by pressure injection methods, in particular under the foundations of the receiving hopper and supports of gallery No.…”

Abstract. The emergency condition of the mine surface facilities including a coal wash plant, a crusher, a bunker and three galleries, is considered. As a result of a complex of engineering-geological and geophysical surveys, it is established that the significant deformations of the foundations of the structure are caused by the zones of weakened (unconsolidated) soil in the bases of the foundations formed due to landslide developments in the bulk ground mass. The article describes the techniques for justifying the technological parameters of the consolidation grouting of soil bases including computer modeling, forecasting of deformations of the natural and consolidated ground mass, analysis of the stress-strain state of soils in the most dangerous area. The effectiveness of the adopted scheme of consolidation grouting of soil bases according to the approved methodology for elimination of the emergency condition of the mine surface facility was confirmed. The limit values of the calculated horizontal deformations in the soil bases of one of the supports of the galleries are determined. To prevent the indicated deformations, it was recommended to provide an additional row of injection wells with a depth below the border of the loosened soil zone.

In this article we will discus the usage feature of the ground penetrating radar (GPR) for the solution underground geotechnologies problems. One of the main problems by the usage GPR method is that the surface of the workings is shielded by metal elements of support (frames, fittings, tightening and other). In this article we suggest to use one- dimensional GPR-scanning method instead of traditional GPR-profiling method. We assume that the scanning will be performed on the development contour in areas free from shielding. For justification one- dimensional GPR method we propose a mathematical model for the propagation of an electromagnetic signal in an inhomogeneous medium based on classical equations of electrodynamics. We also present a numerical implementation of it, which confirms the validity of the accepted problem statement.

“…Along with the development of methods for fixing of ground bases, the issue of determining rational ranges of their technological parameters is topical. Existing analytical methods quite accurately determine the parameters of fixing, however, they do not take into account the structural heterogeneity of the massif, are based on empirical dependencies and have limited ranges of physical and mechanical properties [5][6][7]. More accurate parameters are obtained when integrating numerical modeling and forecasting methods based on basic and local models which are able to take into account the structural features of ground base, the presence of anomalous zones with low physic mechanical properties [8][9][10].…”

The results of engineering and geological surveys to the ground base of a mining and technical building, composed of man-made filled-up ground, are presented. A simulation of the stress-strain state of a fixed ground base was carried out. The analysis of changes in the geomechanical state of the ground massif as a result of injection compaction is presented, on the basis of which recommendations are given on adjusting the parameters of the injection technology.
