| description | The article presents the results of scientific researches of determining the optimal ratio between the dump truck body capacity and excavator bucket capacity during the operation of excavator-auto-mobile complex under the conditions of developing overburden in the quarry of Sosnivske granite deposit.
According to the analysis of the scientific publications it has been established that there are different scientific approaches to providing effective work of the excavator-motor complex in the quarries. However, in the majority of works importance of observance of optimum correlation between the body of dump truck and bucket of excavator for maintenance of high-efficiency work of the complex of the equipment is specified.
In a program complex AutoCAD Civil 3D modelling of a surface of an open-cast mine field is executed and parameters of a profile of routes at transportation of rock mass in a dump for two offered technological schemes of extraction of fluvioglacial adjournment on overburden bump are established. On the basis of results of modeling and taking into account the mining and geological features of the open pit, we calculated the duration of dump truck trips for the two proposed technological schemes of extraction of fluvioglacial deposits and determined the optimal ratio between the capacity of the dump truck body and the excavator bucket capacity. For the first technological scheme of the overburden removing the duration of dump truck movement makes 4,03 min, and the ratio of dump truck body and excavator bucket capacity is 5,64; for the second technological scheme of overburden removing these values make 11,67 min and 8,16 respectively.
In the case of use of Volvo EC460BLC hydraulic excavator with a backhoe and bucket capacity of 2,1 m3 at the overburden step of the pit, it is recommended to transport the rock mass to the dump by dump truck with the approximate body capacity of 11,84 m. At use of the same excavator, but with a direct shovel, it is recommended to apply dump truck with capacity of a body of 17,44 m3. |
