1、附录 Lane Road, linking large-scale engineering practice Kung Chenpatriotic NavyHigh Court 1 Project Overview 80 during the late 20th century, wrote Hill gold deposit found in the mining area southeast of 27 # pulse, thick veins, not low grade, substantial reserves, so they changed the implementation
2、of the expansion project, two shaft extension to build a new concentrator, production After the production capacity of 150t / d. Cyanide-wide mud - a new zinc concentrator replacement process # pulse wellhead located in the vicinity of 27 to deal with the main ore of the Hang Hau, Hau sunny ore depu
3、ty. Hang the two away from the 685m, sunny Hang ore to the surface by the ZL-30 shovel 5t capacity dump trucks loaded to the concentrator. Change the design of the expansion project, the main shaft 27, # network can balance the hammer for double upgrade to 8-de-sac under the middle, the middle of a
4、high degree of 40m. 8 for the middle elevation of 387m. Enhance the capacity of the main shaft 200t / d. In order to reduce the ore to surface shipping costs and to eliminate unreasonable sunny Hang reverse some of the ore transport, at the same time, surface mining when shipped by the weather distu
5、rbance is planned wells sunny middle extension from 5 to 6 middle and 6 middle elevation of the same design for the 387m. And then select a suitable program through the middle of sunny Hang over 6 ore production, unity to the 27 # main shaft to the surface ore warehouse. This resulted in two shaft e
6、xtension at the same time, and the level of 387m each other through the two wells through large underground works. 2 through the selection and implementation of programs Nature of the works: In 1990, the implementation of plans to change the design of the expansion project, the main shaft 27 # pulse
7、 comprehensive renovation and extension, extension to sunny well. Two output shaft extension 580m, together with the level of 387m through the Transportation Roadway 840m, while its total mine works through more than 1400m. By rock gold mine geological and survey work regulations in the relevant pro
8、visions of, the works are large-scale projects through. Options: 2 shaft in extension, how to achieve the project through to a battle between two options. The first program: sunny shaft extension to 6 middle, 5 # pulse Shihmen see along veins towards the South East prospecting. 27 # clock shaft exte
9、nsion to 8 middle, south and hit marshalling yard and Shihmen 50m, 120m and then south-west vein wearing see 27 1 # clock after the clock change this heading to the northwest. From the ore-forming theory, these two belong to the same network structure with fissures, fracture due to the degree of str
10、ucture and the formation of such factors as time independent of each other and linked to form the two ore bodies. Tunneling along the vein, through the inevitable. Project: 387m roadway through the project design specifications 2 0m 2 5m, large-scale transport of my mine roadway. Upon completion, th
11、e sunny middle of all of the above Hang Hau 6 ore by the middle of Ingate 2 2 2 sunny second shaft extension program works less. July 1991, wearing Shihmen see 5 # clock pulse after the south east will open up and prospecting, to early 1992, prospecting extended nearly 600m, this time the main shaft
12、 27, # network extension just to the middle 8. In order to speed up the pace through to improve the operating conditions of 6 wells from the middle of sunny 5 # pulse prospecting tunnel test 6543 points, with 27 # 8, the middle of the north side of the pulse Ingate 20m direct directional boring, str
13、aight-through works of about 400m. Program to determine: the advantages of the first program is for the purpose of prospecting, exploration through integration with Health； shortcomings have long distance, multi-turn, driving conditions, even if the link, because of the need to conduct quasi-cutting
14、 projects such as mining, making it difficult to play a shipment Route task. The second program of the advantages of the short distance through the construction conditions, and the backbone of the transport roadway almost no turn, could significantly reduce the time period, cost savings, the impleme
15、ntation of the program, by the second. Vertical slide shaft, the use of vibration into the tub drawing machine, the motor vehicle 4t # connections to the main shaft 27 to position the surface ore. In addition to Hang Hau sunny 5 # pulse along the veins of iron ore prospecting in the gold veins with
16、tunneling, the straight-through works by more than 400 m through the veins of rock are the crystallization of limestone footwall diorite and neutral, hard rock solid, is not entitled conservation, without gushing, but no fault, fault and fracture zone. Drifting through the works of the major organiz
17、ations of workers from sunny Possession issued by the production plan construction section. Most of them alone the first tunneling project is planned on 28m, that is, to complete a day of rock blasting and Java tasks； but have also organized a few months of the so-called rapid tunneling, that is, fo
18、ur classes daily, every two In small classes to complete a driving cycle. In this way, the maximum driving speed of each month 84 7m. To drift through the construction in November 1992, Hang Hau sunny east measuring point from 6543 is also driving more than 200 m, underground transport distance and
19、ventilation, worker efficiency, and therefore decided to Pulse 8 and # 27 on the north side of the middle Ingate relatively boring 27,802 points. The whole project lasted 2 years, survey work in the mines, the general reference measurement unit 243 geological team 5 accuracy of the measurement resul

Corresponding surface of the horizontal control network accuracy. I mine for many years through the application of tests that, 243 Geological
