| 摘 要： | 目前，我国年钢铁产量快速增长，造成市场上铁矿石供小于求，价格快速上扬。铁矿为北京市允许开采矿种，保有储量仅2亿吨，可供现有铁矿山开采35年，因此应加大铁矿资源的勘查力度，增添新的矿产地，满足钢铁生产的需求。北京密云、怀柔北部山区的变质岩中鞍山式铁矿石，为主要找矿方向。

| Abstract: | The output iron and steel is increasing rapidly in our country at present, and accordingly, iron ore supply falls short of demand on the market, which leads to a sharp rise in the price of iron ore. Exploration of iron ore resources is permitted by the Beijing municipal government, but the available reserves are only 2 hundred million tons in the Beijing area, which will probably allow exploitation of 35 years by Beijing＇s existing iron mines. The pressing situation of iron ore supply makes it necessary for us to enhance exploration and find new deposits so as to meet the demand of steel production in China for iron ore resources. For the Beijing area, the ore prospecting orientation is to find Anshan-type iron deposits in metamorphic rocks in northern mountain areas of Miyun County and Huairou District. |
