JUSTIFICATION OF TRANSPORT WORKS IN THE CONDITIONS OF A BLOCK QUARRY

The increase in oil prices, consumables and tools is necessitate the re–equipment of mining enterprises Ukraine. share automobile transport reaches 35–50 % dimension blocks production costs.
 purpose work to determine transportation costs (TC) 1 m3 depending on volume distance within quarry; improving plan by solving problems linear programming.
 Fuel consumption block TC for three models front–end loaders (FEL) were newly calculated basis a comprehensive study. A comparison economic feasibility FEL dump truck (DT) use certain conditions have been made. rationalization (RP) quarry was proposed.
 research performed at gabbro quarry, which using CAT 988F (1) DT KrAZ–256B. FELs 988H (2) 986H (3) adopted comparison.
 average annual fuel determined: among considered research, consumes least, currently used enterprise 22.7 9.7 more compared (2), respectively, similar conditions. Trade economically expedient with up 300–400 m.
 It determined that trade 5.3 12.6 lower, (1).
 This paper also considers problem FELs, from several banks must be distributed between storage areas, provided minimize TC. According proposed RP transportation, savings will 13 initial conditions, monetary terms 41538–48639 UAH/year model. replacement reduce (47000 UAH/year) current 285303.5 UAH according RP, 23.7 (88476 less than application before rationalization.
