Prediction of the effects of underground mining on the surface is connected with the necessity to verify the coefficients of the theoretical calculation of movements and deformations of the slope of a subsidence trough. One of the methods used to verify the coefficients of the theoretical calculation is the reverse evaluation of theoretical drops verified from the results of direct measurements of movements of surface points. The resulting movement of the surface point is resolved into a horizontal component (shif...

In the underground mining there are many sources of water hazard. Among them, there are water hazards from underground water reservoirs, located in old workings. Mine water inflow from such reservoirs can occur within a few seconds. Within the moments of a sudden and large water inflow, it is most often impossible to withdraw a crew from an endangered front of a mining excavation. In order to eliminate existing water hazard, exploratory boreholes drainages of water reservoirs are performed. In this paper the autho...

The preconsolidation pressure is an important parameter that determines the value of stress history exerted in the past on the subsoil in the geotechnical engineering.
