Stripping dragline excavator casting process in the application of open pit coal mine

The job site, a single bucket excavator to help the brush work, with truck traffic conditions,[link widoczny dla zalogowanych], transport trucks are also made extended flat plate material, do not have (continued on page 44) * 44 * Opencast Mining Technology No. 5, 2009 Silkworm Yu storage ring (1) truck parking level area to live, work the brake switch to the brake position; will also hit the parking brake switch and the parking brake applied position indicator lights, disconnect the electrical control cabinet power switch. (2) from the right side of the electrical cabinet 714 and 714A of electric wheel line on the terminal blocks TB4 removed, and the remaining line of fastening pressure well. (3) FL191 plate extension card extends MF416 card after this card with a short cable 32 feet and 30 feet shorter then connected. (4) control the power switch is closed, the MF416 SA2 on the front panel switch to position, adjust the frequency adjustment knob 1414 card set FL236 AR plate lights, if the parking brake light is off the module and the line is working. Instead the judge for the sport and its related line fault detection module. (5) After testing, restore the removed lines. Test Method 2 using FL191 plate the frequency of occurrence of feature 1137 card, by changing the line, in the parking state, the 1137 cards have access speed analog signal motion detection module, in order to achieve its purpose the relevant line function tests. This method can be adjusted because of the frequency, the test card can be measured simultaneously translated in 1468 by a numerical simulation speed can be tested more accurately the speed of the module value of protection action for compliance. Here are the steps a little. 6 Conclusion This article describes the contents of the pit in Heidaigou electric wheel truck maintenance practices have been applied to reduce the damage to the parking brake effect is remarkable. As technology continues to mature, mining electric wheel truck (including domestic vehicles) have been used in all hydraulic disc brake, parking brake structure similar. Associated with the parking brake circuit and anti-chain of the basic principles of misplaced circuit is also very similar, so this article on other manufacturers to produce different models of electric wheel truck, the maintenance of the parking brake also has some reference and reference value. (Continued from page 32) Truck traffic conditions, a single bucket uprooting power reactor operations. (5) bulldozer, a single bucket excavator to get it done for dragline flat plate dragline shovel is in place you can walk down the heap operations. (6) dragline bench in the high-tension side of the trench work, the abandoned materials do first extended flat plate, extending the width of flat plate width to meet the design after the abandoned to the waste dump. (7) When the expansion to meet the design width of the flat plate, the pull-down stack for normal shovel operation. (8) dragline operation is completed, showing the steps of coal, near coal dump out the side of the ditch. Operating in this way can ensure the minimum amount of bulldozers bulldozing, blasting operation before throwing A bulldozer operating capacity C B D rock pile after blasting throwing shovel brush to help job location. {High-level segment F dragline ditch drop-down operating table that the initial platform dragline dragline operation is completed H Figure 8 dragline distance of the shortest operating procedures, and meet the normal dragline operations continue. Of course, draglines operating procedures also need to continue research in order to achieve the best. Program graph on the left there are two lines,[link widoczny dla zalogowanych], the amount of the first line down the back of the heap to ensure that the minimum rotation angle; second line to ensure that the heap back to the front corner of the minimum amount of down. Two lines are not fixed,[link widoczny dla zalogowanych], need to step height, mining width, the width of extended platform at any time to adjust. In short, to ensure that the minimum dragline back to the corner, and the shortest travel time is the key to improving its efficiency. 5 Conclusion large open pit coal technology, any technology has its advantages and disadvantages. How to ensure the optimal choice under different geological conditions of mining school in the mining process is more important content, and research in the mining process to determine the conditions, in what way to ensure its maximum capacity of this technology is also very important. Bucket continuous Ding Yi, a single bucket of a truck stopped in the domestic mining application process is very satisfactory. 2007 dragline input system is the new process technology, and the world is not applied under the same geological conditions precedent draglines. But the dragline system can solve the shortage of domestic oil, truck tires in short supply and a series of drawbacks,[link widoczny dla zalogowanych], so need to continuously put forward new ideas, optimized mining plan, so that better use of dragline system.
