Marrow 82a74100. Ⅲ Figure 2 holding seepage wells built before the emperor Man Run line control bar graph from Table 2 and Figure 2 shows the radiation well Dahongshan holding tailings seepage, the February-July 1999 infiltration of each holding in the 53 day and night. 28m. To l2l_92in, the average water saturation line down 1.4in. From the field situation, the dam slope outside the swamp has disappeared, the soft parts of the original has been the consolidation of the stability of the main dam to reach the specification. (Continued on page 27) Zhao Yu into the 2l century Cambodian I Torr exposed mineral soil type loading equipment Z7 with the B, j-~ as power brakes, the output power back to the AC motor, the speed can increase the Loaders to increase the total loaders electronic control system monitoring the efficiency of the entire operation process. Within the maximum speed of the engine output power greatly. Dresser4000 Wheel Loader with mechanical transmission, equipped with a modulation from the tuner, built-in modulation of the brake and full power shift planetary gear transmission; power button controls the hydraulic system; z single-arm working device, excellent overall structure and automatic lubrication systems; cab good vision, sound, heat, shock absorption, and easy operation, high efficiency machine. Large wheel loader development: strengthening dynamic parameters, increase power, increase bucket capacity, continue to large-scale development; the introduction of new structures, such as a variable to accommodate two-wheel torque converter pump, high speed devices, advanced hydraulic z-type connecting rod system and to improve the operation, to strengthen control and monitoring equipment, development of mechatronics, intelligent products; in the hydraulic mechanical transmission based on the development of an electronic computer-controlled diesel engine driven; improve driver safety and comfort of play machine efficiency.

(Continued from page 22) the production of transportation costs. Meanwhile, the design combines advantages of mining technology and equipment available, full use of mining technology and equipment available to reduce capital investment. On the other hand, designed to help expand the use of the extension of the open deep on the latest results, combined with the geological and topographical conditions of the stope, economical and rational use of steep slope strip mining sub-way, not only in infrastructure greatly reduces the time to help expand the infrastructure to help expand , reducing the amount of infrastructure investment; and because it's a steep slope mining, reducing the realm of the rock, thereby reducing the production process and unit volume of stripping rock mining costs. 4 Conclusion In the current economic benefits of mining enterprises in China generally poor conditions, the secret expansion of iron mining area of 4 to help the company extend the design work carried out, to the revelation of mining enterprises in China are: to give full play to its advantages of technology and assets, relying on science and technology progress in order to overcome the present difficulties and achieve good economic returns. Meanwhile, before the open pit Closure, carefully study its geology, mining and slope conditions, both from a technical and economic study the feasibility of open development and deepening is necessary. Peru Rail company through expanded mining area of 4 extension project to help develop the mining cost analysis shows that as long as the resources of a large Open Pit Mine and reliable, making an extension of research work to help expand the realities, scientific and technological progress, will be able to find to fit in their own development and deepening the program, make an inventory of existing fixed assets of enterprises, enterprise and technological advantages to the enterprise's survival and development into the vigor and vitality.
