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 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. 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. Henan Hongxing Mining Machinery Co., Ltd is a large-sized high frequency screen, magnetic drum separator manufacturer, and the mining equipment we researched and developed with great concentration plays an active role in the mining and ore beneficiation industry and is one of the indispensable mining crushing equipment in the mining industry.
Today is the1025′ period, China’s economy will be strong up the development of construction machinery industry, an important and sustained power, benefit from this, coupled with business innovation and continuous improvement of competitiveness of China’s construction machinery, mining equipment industry will continue to remain high. Construction machinery, mining crusher market’s rapid development and promote China’s construction machinery, mining equipmentmanufacturers to grow and improve. Statistics show that China’s construction machinery, mining equipment industry rapid development, the enterprise strength to be improved continuously. times of information technology. With China’s sustained and rapid economic development, global engineering, mining machinery industry focus to China to speed up the transfer.
In the past two years, the national mining machinery such as ball mills and hammer crusher, engineering machinery sales market wide sales outstanding, so that our country than North America, Japan, Western Europe became the world’s largest construction machinery, mining machinery market.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.
