Essay

In dissertation vital task from substantiation of technological parameters (advance rate of stoping face, angle of arc line of stoping face) of thin flat coal seam extraction is solved. It is established that during increasing of advance rate of stoping face pressure of power fluid in mechanized support units decreases by logarithmic dependence. It proves about increasing of potential energy in rock massif. For the first time received dependence that is a basis at choosing operating modes of mechanized complex. It gives an opportunity to determine necessary reaction of mechanized support units and allows effectively extract thin coal seams with velocities more than 5 m/day. Results of dissertation work are taking into account during extraction of low-thickness part of seam d4 in conditions of PJSC "Mine management Pokrovs'ke".
