【摘要】：在全球范围内，铁矿石需求量高速增长，而国内铁矿石产量相对不足，这给钢铁企业生产带来巨大压力的同时，又是从事铁矿产品生产企业一个良好的发展机遇期。鞍钢作为国有大型钢铁公司，目前可以掌控的铁矿资源量约占我国已探明铁矿石储量（680亿吨）的13.04%，占辽宁省探明储量的67%。通过对铁矿床深部及其外围资源潜力的详细分析，初步估计潜在资源量可达170亿吨（不含已探明储量）。但目前鞍钢铁矿石产量仅占全国总产量的5.79%，尤其以鞍山及辽阳弓长岭周边的铁矿资源潜力巨大。现有的齐大山铁矿、大孤山铁矿、眼前山铁矿、东鞍山铁矿、鞍千矿业（胡家庙子）铁矿和弓长岭露天铁矿等6座露天开采矿山，和弓长岭井下铁矿山优良的资源储量和开采条件，为新的市场形势下扩大开采规模提供了可靠的资源保证。上述7座铁矿山采区大多已有几十年的开采历史，随着露天矿山向深凹开采的进行，矿石产量规模呈下降趋势，在一直没有大的后续建设投入的前提下连续超产多年，也导致各矿山生产参数难以满足矿山正常生产组织要求，设备消耗上升，铁矿石产量不足造成选矿处理能力闲置，严重影响到矿山总体经济效益。同时，由于多年的超负荷生产，大部分骨干矿山已到了必须扩界和开采过渡时期，目前设计境界内的矿量已严重不足，矿山服务年限已到了相当危急的时刻，急需进行矿山项目的建设。基于以上原因，从维护矿山企业可持续发展的角度出发，鞍钢集团公司拟对自身矿业发展战略进行进一步规划，满足集团公司对原料的需求，提高老区矿山生产工艺水平和总体经济效益，打造高效稳产的百年矿山。鞍钢集团以鞍钢政[2010]90号文《关于对鞍山钢铁集团公司老区铁矿山改扩建规划项目予以核准的请示》及附件“项目核准申请报告”上报国家发改委，对矿业公司未来10年的产量进行了规划，对具体增产项目和为前期在建工程的配套项目进行了详细的说明，并对拟在未来5~10年建设的后续矿山项目进行了展望。规划项目实施后到2015年矿山的铁矿石产量为6950万吨/年，铁精矿总产量为2300万吨/年，新增铁精矿750万吨/年；到2020年矿山的铁矿石产量为10100万吨/年，铁精矿总产量为3000万吨/年，在2015年基础上新增铁精矿700万吨/年。该规划是矿业公司未来10年发展的总体规划，共包括铁矿山改造续建和新建、选矿厂新建扩建、尾矿库改造扩容在内。具体有：对前期实施的项目进行一定的配套工程建设；对正在生产的齐大山铁矿、鞍千矿业铁矿、弓长岭独木采区进行改扩建，延续这些矿山的生产能力；对已完成项目前期工作的关宝山铁矿采选工程进行建设；对风水沟尾矿库和大孤山球团厂尾矿库进行扩容改造；张家湾铁矿建设、谷首峪铁矿建设、西鞍山铁矿及选厂建设、黑石砬子铁矿及选厂建设等。本文针对铁矿山改造项目，运用项目管理、流程分析和再造等管理理论，结合相应的数学模型，，分析研究鞍山钢铁集团公司老区铁矿山改建规划的需求，给出相应的流程优化方案。通过对改建流程中存在的问题的分析，建立适合本企业的流程优化方案，为鞍山钢铁集团公司老区铁矿山改建提供方面提供支持，取得高效、完善的成果。
[Abstract]:In the global scope , the demand for iron ore is increasing rapidly , and domestic iron ore production is relatively insufficient , which brings great pressure to the production of iron and steel enterprises , and is a good development opportunity for the production enterprises of iron ore products .

As a state - owned large - scale steel company , Anshan Iron and Steel Co . , Ltd . is currently under control of 13.04 % of our country ' s proven reserves of iron ore ( 680 billion tons ) , accounting for 67 % of the proven reserves in Liaoning province .

Most of the above seven iron mine mountain mining areas have been mining history for several decades . With the development of open - pit mining and deep - concave mining , the production scale of ore is declining , and the production parameters of each mine are not enough to meet the requirements of the normal production organization of the mine , the equipment consumption is increased , and the shortage of iron ore production leads to idling of the ore dressing treatment capacity and seriously affects the overall economic benefit of the mine . At the same time , most of the mine shaft mines have been in need of expanding and mining the transition period , and the mine service life has been seriously insufficient , and the mine service life has reached a critical moment , and the construction of the mine project is urgently needed .

On the basis of the above reasons , from the perspective of maintaining sustainable development of mining enterprises , Anshan Iron and Steel Group Co . , Ltd . plans to further plan its own mining development strategy to meet the requirements of the group company on raw materials , improve the production process level and overall economic benefit of the old district mine , and make a detailed description of the output of the mining company in the next 10 years .
By 2020 , the output of iron ore in the mine is 101m tons / year , the total output of iron concentrate is 30 million tons / year , and the iron concentrate is added 7 million tons / year on the basis of 2015 .

The plan is the overall planning of the development of mining company in the next 10 years , including the renewal and construction of iron ore mountain reconstruction , the newly - built expansion of concentrator and the expansion of tailings pond .
The production capacity of these mines will be extended to the production of Zidashan iron ore , saddle thousand mining iron ore and the exclusive wood mining area of Gongchangling .
carrying out the construction of the Gubaoshan iron ore mining project which has completed the pre - project work of the project ;
The tailing pond of Fengshugou tailing and the tailing pond of Dawushan Pellet Plant are expanded and reformed ;
The construction of Zhangjiawan Iron Mine , the construction of the Valley Shouyu Iron Mine , the construction of the Iron Mine of the West Anshan Iron Mine , and the construction of the selected plant , the blackstone iron ore and the construction of the selected plant , etc .

Based on the management theory of project management , process analysis and reconstruction , this paper analyzes the demand of rebuilding the Laohuashan Iron Mine in Anshan Iron and Steel Group Co . , Ltd . and gives the corresponding process optimization scheme . Through the analysis of the problems existing in the reconstruction process , this paper sets up a process optimization scheme suitable for the enterprise , and provides support for the reconstruction of Laohuashan Iron Mine in Anshan Iron and Steel Group Co . , Ltd . , and achieves the results of high efficiency and perfect .
