DHC-12 mixed-utility vehicles and ground Emulsion Preparation Research Station


With high accuracy, control stability, not the hydraulic system oil temperature and other factors, and have the same: electric hole in the automatic continuous mix features three varieties of explosives. (Continued on page l5) 15.3 .2 to help adjust the slope of expanding open pit slope design parameters like cracked by analogy. Slope angles of the initial selection of more than 45. ~ 52. Between. This means that, without expansion of gang cases, the slope angle is also considered a security barrier. Mines in production , the actual slope angle of 45. The example of the above. Daye Iron Mine on the plate as the slope angle is 48. ~ 52.5.; Nanfen slope angle iron 48 on the plate.; Dashihe slope angle iron on the plate 48.5. And so on. Since this is a security barrier slope angle, they should strive to extend help as close as possible after the expansion of the slope angle of the slope angle to help the former to reduce the amount of expansion to help improve the economic benefits of mining. Improve the final slope angle, reducing the slope angle difference before and after expansion to help one of the ways to help in the expansion of the slope before and after using different parameters. This can be by adjusting the width of the platform to achieve their goals, because in general should not change the end stages of the slope, while the security barrier platform and clean-platform structure is adjustable. This approach can be extended to help reduce the difference between before and after the slope angle, but not make the same. For example, the rod hammer stope slope angle of the initial selection of 48., Slope angle of the end of stage 65. The final two steps and the platform after paragraph width 10.4m, doubles as a safety barrier and cleaning purposes. If the slope angle after EXPANSION remains 48. And the width of the platform after paragraph 4.4m, only a platform from the security barrier, not cleaning. If you press after EXPANSION slope angle is 45. Terms, and the platform after paragraph width 6.8m,[link widoczny dla zalogowanych], but there is no cleaning effect. However, if a change of the platform structure, the two 6.8m wide and 3m wide platform into a safety barrier and a 10.6m-wide platform to platform is finished cleaning base possible and reasonable . By this means, can help to expand after the slope angle increased by 4. To reduce the amount of 3.2 million expansion to help. Than the rejection does not adopt this approach to help reduce the amount of expansion of 57 million in production costs and 2000, economic benefits are considerable. 3.3 to increase the height of step wells and improve the final design of slope angle in the past, because of perforation and blasting equipment, backward, Sheng steps are generally not final and the slope section, and each level is to stay clean safety barrier or platform, the number of multi-platform, but the effect is poor. With the bursting of the technology improves, the final slope is generally used at the blasting or blasting, can reduce the damage of rock mass, to enhance its stability. The development of the perforation device, the design of gradual slope and segment direction. Currently only two steps of a well section. After the cleaning section of this platform and the width of 10m or more in general, entered the cleaning equipment can clean up the slope, however, will cause the layout of the final slope line slowing down, only to adjust the platform width is limited. Which, in the engineering geological conditions permit, the final step should also be the very height, in number and paragraph direction. This helps improve the final slope angle, and easy to arrange platform structure. And perforation of the current technical level of equipment and blast barriers can achieve more complete and paragraphs, and paragraphs and to ensure the safety barrier after the slope has a variety of domestic drilling slope for step and provide favorable conditions section. This rig just ten million each,[link widoczny dla zalogowanych], two more than ten million, but after using this rig,[link widoczny dla zalogowanych], by increasing the slope angle of the final summary of the economic benefits generated would be extremely significant. It has been calculated, bar hammer stope step if for a period of 3 months, so that the final slope of 45., The width of the platform and after paragraph of up to 10.6m, can double as security barriers and cleaning purposes. ... ... ... ● ... ● ... ... ● ... ...

Variety of emulsion explosives and the corresponding ground facilities, the formation of the End (5) production application shows that the car can be the whole of the system running stable charge mechanized system. Explosives simple, into a reliable, job security barrier, easy to operate, charge density,[link widoczny dla zalogowanych], the explosion of the low end base coupled with the hole, breaking effect of physical and chemical stability and good performance, explosives consumption reduced by 25, explosives safety barrier of the set, its performance meets and exceeds the national standard for open air is good, costs are significantly reduced. And self-phase slurry explosives, mine use. Foam in the control of explosives and innovative methods. Ratio of explosives on vehicles using the mixed l million t, especially the net savings (4) The selection of the domestic cost of digestion and absorption of 600 million yuan of international, economic and social benefits, the level of 80 Type T815 Bridge too pull off drive Type in the clouds,[link widoczny dla zalogowanych], and large and medium-sized open pit mine land water and hilltops to drive a car chassis, is very suitable for Taiwan in the mining muddy, bumpy road digging works in a wide range of applications.
