The introduction of modern complex mechanization into the practice of coal mining places high demands on the detail and reliability of forecasting of mining and geological conditions and complicating factors. Such factors at the Vorkutsk and Vorgashorsk coal fields include, first of all, small-amplitude discontinuities in coal seams with displacement of less than 10 m, which due to their parameters are not established during exploration works, so their meeting by preparatory and cleaning mine workings turns out to be in one way or another unexpected....
Recently, in the practice of geological exploration widely introduced modern methods of processing exploration data - mathematical modeling, use computers, improve the methodology of chemical and spectral analysis, technological tests. At the same time, the reliability of the final results mainly depends on the accuracy of the initial data, and the latter - on a number of “small” errors allowed in the exploration process. This is repeatedly mentioned in his works E.O. Pogrebitzky. ...
The distribution of germanium and other impurity elements in brown coals of Mesozoic age was studied (1957-1961) in the deposits confined to depressions of the ancient basement. The coal-bearing strata at these deposits are composed of Continental-type sediments and contain thick deposits of brown coal of complex structure.
