Something about energy consumption in mining

[Zenither6]

Transportation of overburden, within the limits of the open pit surface itself. to internal waste dump and crushing equipment is carried out by dumper capacity from 50 to 70 t, and volume of loading frame from 30 to 50 m3. Transportation of overburden to the external deposit is carried out by belts with previous crushing of material by Raymond Mill. At the present stage of exploitation, six transporters were installed, three of which being permanent and three mobile, in a total length of around 4500 m. The said transportation system also consists of below-level dump stackers and above- level dump stackers having the capacity adjusted to transporters.


Dewatering of the open pit mine is carried out by a system of electrical centrifugal pumps of considerable capacities, due to great inflow of ground and surface waters.The development of the technological engineering company is actually the process of constantly integrating the above technological abilities according to the needs of different Raymond Mill customers.Open pit mine has a complex exploitation configuration with ten developed working sites that are successively activated as per month, quarter and annual production plans. In this plant classification of coal is made depending on its market purpose.


All other supporting activities are performed on the open pit mine such as: construction and maintenance of roads, development and recultivation of deposits. supply of energy sources, maintenance of plants and equipment. The block scheme of the Portlica coal open pit mine is given in Figure 1 where: TSI. TS2, TS3- transformer Sand Making Machine stations, SKDI, SKD2, SKD3  storage of oil derivatives (diesel fuels ect.), SKEK  explosive dumps. CDI  tunks for diesel fuel supply, DE  explosive supply, 0l, 02, 03  working sites on overburden for internal waste dump. LI, L2, L3, L4  working sites on coals (overburden) for external waste dump. DR.0 crushers for overburden, UI. U2. U3  working sites on coal, D.R.U  coal crushers. SEP  coal separation DEP RU  coal waste. DP  dumper. UT  loading machines, loading. BD  bulldozer, GR  grader. Cp  pump station, REC  recipient, R  light.

Simulation of the working processes is performed according to the planned real exploitation factors for a one past year. As a result of such analysis, daily, weekly, monthly, quarter and annual production balances with total consumption of all kinds of energy that are reached in realization of the production processes with the optimum planned parameters.By comparison of balance production parameters obtained by the simulation model and reached in real Vertical Roller Mill system, possible solutions of savings and measures for better maintenance of equipment and plants as well as the increase in technological discipline, are determined.Coal transportation from open pit mine to crushing and separation plant is also performed by dumpers capacity of 36 t, volume frame of 26 m.

For simulation model Mr. Vladislav Kecojevic tested a programming packet generating mass and energy balances as per the following categories: 1.source of supply  place of delivery of excavated resources 2.distribution and transportation system 3.machine  loading place 4.consumer  operating machine 5.useful energy  type of working process or facility Structure of real system within the applied model is defined by a coding system, namely positioning of all the elements Sand Making Machine relevant for running of exploitation processes. The main structure of model is composed of the following functional links:  1. production systems, machine in operation (RM)  place of loading (UM) 2. place of delivery (MD), and 3. consumption- consumer (POT)  equipment (UR)  sours: (IZ) or store house (SKL)
