Analysis of seismic tomography data for definition of hydraulic fracturing parameters in underground coal mines
The article analyzes the issue of reliable estimate of the unloading extent and the variation order of coal-rock massif geomechanical characteristics as a result of hydraulic fracturing undertaken from mine workings. For this purpose it is proposed to use the fracturing value of the studied rock mas...
