LOAD-HAUL-DUMPER PD-1D - RUSSIAN INNOVATION IN MINING
Specification of prototype load-haul-dumper PD-1D is reported in the comparison with the foreign analogs in use in uranium mines of Priargunsky Mining and Chemical Works. The substantiation is given for the use of narrow-web mining machinery in top-downward cutting with cemented backfilling. 31 A picture of the domestic-manufacture mining machine prototype PD-1D is given. Based on the outcome of the commercial mine tests, the conclusions are drawn on the expediency of manufacturing of narrow-web domestic mining machine PD-1D.
