Particular Features of Wave-Field Forming in the Process of Ice Wall Fencing Study at the Mine Shaft by the Borehole Seismic Methods

Summary The ice wall fencing method is applied during construction of shafts and tunnels in water-encroached sediments. The process of this formation is controlled by the number of physical methods, including those of seismoacoustics. The particular features of crosshole wave-field in the process of ice wall forming has been considered. The borehole sparker is used as a source. The quantitative estimation method of the ice wall thickness, as well as shaft full freeze control, have been proposed.
