A positive change for both positive. Not only saves investment and accelerated the pace of mine construction. 2, adhere to the scientific mining operation, formal design, construction tenders in the mine design, after careful investigation and research, decided to request the long hospital commitment. Design of the ore body under the Lukui occurrence conditions and mountain terrain, and the upper part of the soft ore, extending deep deep features. After using the first open-air underground mining methods. The design calculations, although the average stripping ratio of 5.73t / t (6.76m / m), but mine is still good economic returns. In order to meet the characteristics of the local mines, the use of traditional techniques and equipment level, fast production, production management easy. Strip mine the main project and the construction and installation of infrastructure to implement public bidding, by bidding. Select the technical force of the climbing iron ore Zhu bag to complete the task of stripping the main infrastructure projects, the team finished in 2 years time, the amount of the base edge peel 3.29 million m, forming a 13 step, to build a transport and Dumping System, the amount of ore mining 1.7 years with the development, maintenance and mining the amount of 7 months, six months ahead of completion. Stripping in the implementation of infrastructure during the period also helped train local talent, bring out the production team. To choose the civil construction team, the same approach to bidding, construction teams in 52 selected l1, a total of 38 civil works completed, total building area of 26165m. Invested 12.62 million yuan. As the local construction of additional costs are lower. Taken into account by the relevant provisions of the 8 special charge, and only take into account management fees and temporary facilities, construction costs, the corresponding lower investment. 3, the reform of employment system, adhere to the mining town with, mine construction l6I Platinum Mine Design and Construction] 993 No. 6 set to pursue the \various forms of employment system, while paying attention to recruiting minority workers and cadres. Mine construction and production of technical staff were needed to recruit, transferred counterparts, training and other delivery channels to solve, thus reducing the mine life is too large bases. Present, there are 676 + employees transferred to mine officials and permanent workers (mainly equipment operators) 196, 195 contract workers. Rotation of 240 people work 39 + casual. The overall layout of the mine, and do the town with the local Yang Wu combined with the building, changed the past mines \And close the mine and local relations, and promoting national economic development. In conclusion, Lu Kui Shan Iron Mine Construction to build our future provide a good experience, can be proud of choice for small and medium iron mine construction mode reference. Third, the discussion of ideas from our existing mines mining model building point of view, in general, has formed three models built mine, for our discussion and analysis of a national investment, corporate mining operation. Mine under the Iron and Steel Company form. This mining operation is the main form of levy to be invested according to the national plan, the output state determined price allocation price of the implementation of national unity, the basic fixed-product sales, and its advantage is to give full play to the advantages of joint ventures, investment and reliable technology and management + concentrate, unity of command, supply of raw materials is guaranteed. As from mining to iron and steel in the whole process completed within an enterprise, part of the production associated + to maintain continuity. But the main drawback is that this form of a single product, employment fixed, guaranteed for the underwriting, mines social, and live profit and loss, the mine labor productivity is low, running the \mine the current state-owned large-scale mining model, although can play a positive role. But in today's environment of market economy and reforms take time and through practice + and then seeking a more reasonable mode of construction of mine. 2, local investment, local mining operation, autonomous form. This form is characterized by funds from fund raising for provincial, county funding support, custom production, product prices are not necessarily uniform implementation of the national allocation of price, follow the market. Corporate self-financing. The advantage is suitable for low level of deposits in the geological exploration, small-scale mining + can not be less investment in infrastructure, building speed, good economic returns, land acquisition easier. And can solve the rural surplus labor. The disadvantage is that weak financial and technical, production continues to be difficult, mining the rich ore loss abandoning the poor more prone to accidents. From Tangshan of cases, from 1984 to 1986 dollars, the local small-mine investment 97.87 million yuan (about 600 of them for the mining field to 700 million), has built a production capacity of mining and 4.27 million t, per tonne derivative at 23 yuan investment in state-owned mining investment when l / d, construction time is generally 3 to 6 months to put into operation <br /> More articles related to topics： <br /> <br /> <br /> <a href="http://www.krainy.fora.pl/wyspa-piratow,20/iron-ore-bodies-jinshandian-mining-methods-hard-t,4473.html#32861" target="_blank" class="postlink">Iron ore bodies Jinshandian mining methods hard t</a> <br /> <br /> <a href="http://www.rrsport.co.uk/forum/post279482.html#279482" target="_blank" class="postlink">Introduction of five flotation process chemical a</a> <br /> <br /> <a href="http://www.krainy.fora.pl/osiem-szczytow,31/iron-mine-tailings-good-to-improve-the-efficiency,4471.html#32859" target="_blank" class="postlink">Iron Mine Tailings good to improve the efficiency</a></span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/Elveron/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
