dc.description.abstract | The augering mining of thin and very thin coal seams has been
proposed for using the efficiency of this task, related to the stability of
reusable mine workings. The interrelation has been established and
optimized between the support loading parameters in the extraction
working during the augering mining of thin and very thin coal seams with
the stress-strain characteristics of the protective monolithic strip of variable
rigidity. The strength properties of sand-cement stone for the erection of
rigid and yieldable parts of the protective strip are studied. The regression
equations are obtained, which allow to determine the rational force,
deformation and geometric parameters of the “support – protective strip”
system elements during the extraction workings maintenance. | ru_RU |
