Essay

The dissertation is contains a new solution of actual scientific and practical problem consisting, in determination of the factors of coefficient's extract raising during untraditional hydrodynamic coal extraction. Theoretical and experimental investigations have established, that viscosity's augmentation of working liquid is necessary condition of coefficient's extract raising. Investigation's results permitted to working out technological schemes of coal extracting out of the unproductive abandoned seams.
