Essay

The dissertation is devoted to a solution of an actual scientific - applied problem - substantiation of rational technological parameters of packs for increase of efficiency of protection of development workings. Character and degree of influence of travelling speed of clean-ing working face on a roof subsidence is determined near at workout spaces. Influence of relative density of backfill on size of contraction of a pack is established at its interaction with soils подработанной above a coal strata. The interrelation be-tween sizes of density of a rocky strip, its width and travelling speed of working face is determined. Time of flight of particles to a roadway floor is established. On this base rational techno-logical parameters of packs are proved. Are developed and taken over to application on mines SP "Donetsk the coal coked company" and "Selidovcoal" recommendations concerning a choice of rational ways of protection and maintenance вы-емочных developments. Economic benefit of an intrusion of recommendations is received.
