Keli Wo Rogge mine deep level underground mines and mining potential solution to open up

Driving yard ramp (Figure je, h). The results with the previous findings exactly. Mine is to take the deep levels of ancestral recommendation to develop programs for the fall of the following. The program (Fig. 1h) provides a blind driving, auxiliary shaft (to the 1765m level) and two ramps, ramps should be able to avoid spending a lot of investment in the construction of many Transfer Station. This. The first ramp (HC-1) from the country level mine shaft bottom 1465m to 1690m level of excavation Transfer Station, the slope is 6. . The second ramp (HC-2) from the first ramp down the level of digging to l790m Transfer Station, the slope of 8. Since HC-l the length of the larger ramp (about 2200m). In order to facilitate self-propelled transport equipment the wrong car, driving the wrong car width of the larger chamber, set l ~ 2 个 was the wrong car. Driving from the working level from the shaft of the Shihmen to open up the blind. The working level, the motor truck transportation, ore ore shipped to the courtyard, the courtyard play the role of storage tank mines, with the lower loading device. Used to their own devices are installed with mine. Self-propelled transport equipment from the Transfer Station Road will be along the diagonal broken ore transported to the main hoisting shaft l465m level underground ore bin, and then raised to the surface is recommended for self-propelled transportation equipment is 50 ~ 75t diesel vehicles wired with 5 ~ Aunt 6 sets will be able to guarantee the car about l50 million t / a mining volume. Hope Brook Gold Corporation under the Canada underground mine production experience, 2 Kl050E 50t of the Kiruna-type vehicle along a gradient of overhead line l2. Length of the ramp l400m transport ore, to ensure that production reached 3000t. This program allows the amount of dollars per ton the cost of mine development (at 1991 prices) Roger Bick rive lower mining design institute 4260 rubles / t, ratio of Mining Research. Proposed programs to reduce l890 rubles / t.尤比列伊纳亚 mine, mine guards and Lenin mine the deep level of development means the difference between mine and the motherland, but the need for transformation of the main elevators to carry out small and then ramp the same level of development of the final link up (see Figure le) and Keli Wo Rogge compared the design of mining institute. Explore these ore per tonne ore by volume can reduce the cost of 900 ~ l000 rubles / c. l995 No. 2 MINE DESIGN AND CONSTRUCTION The deep level mining heap problem, Keli Wo Rogge mining design institute is basically a way by side lane quasi prepared. Comparison with existing programs. This design uses only considered in the next two clock drive to expand outside the confined area transportation Lane. Study for a new level of quasi programs more affordable among the different use of the previous quasi programs on the determination of optimal conditions for research. Deep level of the joint proposed quasi programs. By this program, not by the quasi deposits in the work, but the mine field into a number of smaller quasi mining area. Mining area is by small deposit thickness along the strike length, position and angle of each ore body divided by the difference. Figure 2 shows the recommended level of guards mine 1670m quasi programs. The deep level of the proposed joint program allows prince Yu quasi 2 ore l670m level guards quasi programs recommended level of 63 quasi various transportation projects than the original roadway design to reduce 【5 to 25. Conclusion requirements to make the economic situation before the mining area over the next Keli Wo Rogge, a new mineral of the deep levels of non-traditional (1500 ~ 2000m) to develop and adopt standards program. Research results show that competition is the most reasonable solution: the mining area around the mine's main elevator under the small-transformation, a direct upgrade to the depth of the ore increases l50 ~ 250m, the lower the level of service shaft equipped with ramps for the blind open, slope Road direct dig to the bottom of a main hoisting shaft a horizontal shaft bottom. With this program, the total amount of ore per ton cost of developing the original design lower than 4200 ~ lgOD_ total cloth / t transport level quasi joint programs to be used. Can guarantee the original design was quasi engineering programs to reduce the ratio of 15 to 25. Veteran translated from Ukraine ~ ~ M, JFFI \advantage of interest and commitment of resources, Sichuan Province, Mei House silkworm second base on the site selected Panxi steel Xichang City, 63km away from Dechang County of Liangshan the motion passed. At the same time that Panzhihua Iron and Steel:: base of the building will officially launch the second base Panxi 3.09 million t of steel for the annual output of large iron and steel enterprises, nearly eight ask the relevant departments and units to carry out further feasibility studies in Dechang County construction workers ashamed . Outlook for the Langqiang husband conducted to create conditions for cross-project construction. (Magazine correspondent J
