Kiruna iron ore room ultra-high

Iliac arm forward at the target correctly. Drill with the pressure of gas, electricity, water flea is for the straight circle (1) phase. Control panel settings to force the purpose near the vehicle with a power askance camera (5) full remote control room (B) in the. Dry drilling system, including La separator (T), l Pa measures over the fan (8). To exclude debris generated by drilling the first Sireba269 car in July 1987 delivered to Ji Luna mine. The machine is observed by a driver through the closed circuit television monitoring automated drilling, he sat near the roadway can be adjusted to control room temperature. Disc conveyor frame storage reservoir has 54 drill drill pipe, each length of 1.875m, automatically scheduled t00m drilling deep holes. Drill a hole in the end, the automatic control system to recover the drill pipe and put it back into the reservoir filler conveyor disc holder. In order to meet the deep straight hole drilling requirements, the use of hole drilling technology. Fried rice cake to ensure that only this technology to drill that deep hole capacity and achieve a satisfactory vertical. Drill pipe with a guide flange Gao group on the shore in the uranium to reduce the borehole deviation ■ 0:: hammer drill hole driven by the high-pressure compressed air to accelerate the drilling speed and a safe to blow out the 岢 deep hole crumbs. As the drilling debris and dust collection port, to the environment from pollution under Hu, debris and dust particles through the straw to exclude coarse debris delivered to the separator, the first 19eo No. 6 line filters 45 , and then released into the atmosphere. Embedded in the hole on drill pipe, auto sampler tubes were connected with the dust emission, so that samplers can be removed from the drill cuttings samples a small portion. Samples stored in 54 samples can be loaded rotating drill pipe box one sample each. Samples were collected and analyzed, the results will be predicted as a late burst of ore grade and quality purposes. How to make the initial hole is precisely the direction of the direction of intended hole is a very complex issue. Calibration of instruments with complex each hole will take up too much and waste a lot of drill work process time, so this device must be simplified so that the operator can self-control. Hole, your goals should be the accuracy of the depth of ± 1. Lane along a reference line with the laser that the laser beam so tracking the target, indicating that the drill rig in the direction of drift. Then determine the angle of hole, using a pocket computer program to calculate tilt angle by to meet the dimensional requirements of nets hole explosion. Sixth, improve and enhance the car as a new product Sireba straight at the beginning of drilling deep holes in the back and forth several times modified. It is not necessarily the way to use automatic control of drilling, and sometimes it can also be under the control of drilling in the artificial. Initially, Ji Luna in a test stope ore drilled a hole 40m deep, and then in a higher required stope drilling a deep hole for the 60m of the results showed that in the deep hole drilling and test mining both are very promising field. The next step is to strengthen the application of drill rig to make it better adapted to future high stope mining. S ~ mba269 car is equipped with drilling llSmm from the hole of the COP42-type DTH hammer drilling 165ram change hole is equipped with the COP62-type impactor. Disk storage conveyor drill pipe must be replaced by a larger one, in order to extract the diameter ll4mm the drill pipe. To meet the COP62-type impactor to increase the gas pressure to exclude the 80m deep hole in the debris. Ji Luna allow mine engineers drilling deep sub believe the results achieved to guide other Simba269 car manufacturing. The second piece of equipment from the factory already equipped with ready to use 114ram diameter drill pipe, drilling 165mm hole. Thus, the summer of 1989, 2 car side by side Simba operation can ensure the mine room 80m deep hole drilling can be tough to achieve the scheduled beginning stages of research projects. Seven, twice daily class performance work systems in 7.2h, 1 Simba269 average car hit deep 115 ~ 125m, close to the best class 200m. According to existing records show that the rate of monthly increase in the near future, throughout the two-month period up to 130 \Eight prospects Simba269 the prospect of deep-hole drill rig depends Ji Luna ore mine in the room very high test that a lot of caving experience. Ji Luna personnel mines have been carried out deep twilight I broke all the results of the study showed that almost make high production stope ore mine in Ji Luna and as much as large-scale sublevel caving. 2 sets of second-generation Simba269 under the car is being equipped, it can be stored with a diameter of drill pipe lSOmm disc conveyor.
