【摘要】 目前,铁矿石作为国民经济发展必须的大宗矿产是不可替代的。钢铁工业发展对铁矿石的需求也将有较大增长。我国的自产铁矿石远不能满足钢铁工业的需求,进口铁矿石量逐年增长,1991年的1855.9万吨增加到2000年的6997.2万吨。2003年,我国共进口1.48亿吨铁矿石,占世界总贸易量的26.43%,首次超过日本位居世界第一位。2006年进口铁矿石3.26亿吨,2007年我国进口铁矿石3.83亿吨。随着我国经济的快速发展进口铁矿石的量还要增加。随着表层与浅层铁矿体的开采,一些矿山出现相对的危机。面对这样的问题,用以前的找矿方法已经不能迅速找到深部的隐伏矿体。如何迅速、准确的发现深部矿体是一个急待研究的课题。面对这样的问题,我们用EH-4进行探测研究,通过对大台沟隐伏矿床的探测研究,得出以下结论：矿体的总体走向为北西向,南西倾,倾角较陡,矿体从矿头向下延伸约500米,这为矿山开发新的资源基地提供了科学依据。该方法对本区的航磁特征有很好的验证,特别是深部铁矿资源探测具有良好的借鉴意义。本次研究表明连续电导率测量系统对鞍本地区深部铁矿资源具有良好的探矿效果,大台沟及邻区(小台沟)具有一定的铁矿资源潜力。研究采用的方法和技术手段方便快捷,科学准确,直观有效,且不受地形地物的影响。随着经济发展对铁矿石的需求,这一地区可为今后的铁矿开发提供资源储备,应进一步开展地质工作,但要考虑矿体埋藏深度对开采技术条件带来的影响。更多还原

【Abstract】 At present, Stone of Iron is necessary and irreplaceable in the Process of development of economic. Development of Iron and steel industry on the demand for iron ore will also have greater growth. China’s iron ore production for much of the iron and steel industry can not meet demand, iron of imports of will grow each year,18.559 million tons 1991 to 69.972 million tons of 2000. In 2003, China has imported 148 million tons of iron ore, in the world total trade volume of 26.43 percent.2006 imported 326 million tons of iron ore,2007 imported 383 million tons of iron ore. As development rapid economic of China’s the iron ore import volume will increase.As with the shallow surface of the iron ore mining, Some of mine will be crisis. Faced with such the problem, with the previous method can not quickly find the buried deep ore body.It is a priority research topic How quickly and accurately did find the deep ore body.Faced with such the problem, We use the EH-4 detection research, Through concealed deposit detection research of the Da tai gou. Draw the following conclusions:Ore body of the overall direction to the North West, sw dumping, steep angle quickly. Ore from the mine head downward extension about 500 meters, This mine for the development of new resource base to provide a scientific basis. The method of the district aeromagnetic characteristics is a good verification. Especially deep iron ore resources exploration has a good reference. This study shows that the conductivity measurement system for the saddle in the region of deep iron ore resources prospecting has a good effect. Areas of Dataigou and xiaotaigou is a potential iron ore resources. On the methodology and technical means to facilitate fast and accurate science, visual effective, and the terrain features from the impact of. We should be further geological work, but to consider mining ore bodies buried on the depth of the impact of technical conditions.更多还原
