Abstract

In the work, the peculiarities of shock-wave diagnostics of voids and the estimation of load of lining of mine workings based on the construction of cartograms are considered. Mapping is the most visible and informative way of presenting measurement results. For mapping, select such areas that provide equal scales along different axes in the image sweep the surface. The image format contains options for automatic contouring, displaying contour lines, and printing of levels of values for the corresponding contours. The mapping operation itself automatically makes it possible to estimate the depth of the cavities being monitored, and this definition is accurate in terms of area and relative depth, since it is based on automatic processing of measurement results. Only refinements are needed to determine the absolute value of the depth by measuring methods at various bases or drilling holes.
