Korovyaka E. Grounding of Parameters of Technology for Thin- veined Gold Deposits Exploitation in Ukraine

The dissertation paper concerns the problems of grounding of technology for thin-veined steep sloped gold deposit mining on the basis of ore delivery proc-ess improvement in mines. The following systems for gold mining on Ukrainian crystal shield are recommended as a result of theoretical, analytical and experimental research:1.with ore shrinkage when thickness of ore bodies is m < 1,2m; 2.with diagonal stripes up-dip when filling mass is compacted by means of blasting m < 1,2m; 3.with packing a goaf use of a flight conveyer to deliver broken-down ore along filling mass when stope is of variable shape both on slope and strike (m = 1,2 - 1,5 m); 4.with packing a goaf while using compact loading and delivery machines (m > 1,5m). As there are no real units the technology was implemented to determine rational parameters while exploitating thin-veined steep sloped deposits with the help of loading and delivery machines. Besides, it was used in "Initial Demands" to manufacture compact loading and delivery machine for thin steep sloped veins. Those "Demands" have been agreed with the IGTM of the NAS of Ukraine, confirmed and transfered to "Kryvbasproject" SPI.
