Abstract
The utilization of waste rock for pneumatic stowing in the Komsomolets Donbassa mine with coal seams to 1 m thick and dip angles from 3 to 11/sup 0/ is evaluated. Gate roads used for mine haulage by belt conveyors are controlled by cribbings made of timber and of concrete blocks, particularly at junction of working facese by belt conveyors are controlled by cribbings made of timber and of concrete blocks, particularly at junction of working faces with gate goads. Effects of pneumatic stowing on strata control cost and environmental protection are analyzed. Waste rock which has been dumped at spoil banks on the ground surface is crushed by the PZK system developed by Dongiproshakht. The PZK system is installed underground close to haulage roadways. Crushed rock material with size from 0 to 80 mm and compression strength coefficient from 3 to 5 degrees on the Protod'yakonov scale is hauled by mine cars to working faces and stowed by the DZM-2 pneumatic system. Strips of pneumatic stowing at each side of a gate road are from 12 to 15 m wide. Design of the PZM system and of a rock hopper used for accumulation of crushed rock as well as design
