【摘要】 铝工业是河南省支柱产业之一,在河南省国民经济中占据着重要的地位,其可持续发展直接关系到河南省国民经济的健康平稳发展,然而铝土矿资源的可持续供应,却是河南省铝工业赖以发展的基础。因此,在河南省实施铝土矿资源战略显得尤为重要。本文遵循矿产资源战略理论,对河南省铝土矿资源产业发展现状、未来需求、资源潜力及保障程度、环境承受力、省外及境外资源利用情况进行了全面细致的研究和分析。通过对铝土矿资源产业发展现状研究,认为河南省的铝工业高速发展的态势没变,在全国优势地位没变,但探明的铝土矿资源保障年限较低,按现有保有基础储量6.964亿吨折合成开采出的矿石量约2.164亿吨计算,河南省静态保障年限不足9年,属于重度危机。而近几年铝土矿地质勘查的投入力度在减少,深部找矿没有展开。同时认为河南省的铝土矿含高硫矿石、低品位石比率比较高,合计达20%左右,并且民采严重、回采率不足60%;通过对河南省铝土矿资源未来需求研究,认为河南省正处于工业化进程的中偏后期,矿产资源的使用强度处于高峰期。尤其是对铝土矿资源的需求,未来10年内将有可能迎来峰值。同时预测河南省要保持现有铝工业的优势地位不变,未来10年内累计需要铝土矿石3.77亿吨;通过对河南省铝土矿资源潜力研究,认为河南省铝土矿成矿条件较好、含矿岩系分布广泛(约20000km2),虽然在浅部(埋深150-300m)已基本探明,但在中深部(300-1000m)地质工作做的很少,存在较大的找矿空间。对最有可能开发的铝土矿成矿区中的13个有望靶区中深部进行了潜力预测,获得潜力资源量4.4亿吨,折合可采储量约2.2亿吨;通过对保障程度的研究,提出了在制定铝土矿可持续供应策略时应遵循矿产资源消费需求理论,消费旺盛期加大供应、消费衰退期减少供应,从动态变化的角度来提供资源保障,并认为河南省的铝土矿资源基本能满足未来10年的动态需求量;通过对利用省外、境外资源及河南省环境承受力研究,认为河南省利用省外、境外的铝土矿存在较大的空间,同时认为河南省的环境承受力在可控范围内。文章最后,在上述研究的基础上,提出了河南省铝土矿资源战略。并提出了尽快实施新一轮地质勘查工作、提高回采率、利用好两个市场、两种资源等六条具体措施。更多还原

【Abstract】 Aluminum industry, one of the pillar industries of Henan, is of great importance to the national economy of Henan province, for its sustainable development has a direction relation to the healthy and stable development of the national economy of Henan province. The development of Henan aluminum industry relies on the sustainable supply of bauxite. Therefore, it has great significance to carry out bauxite resource strategy in Henan province.In conformity with the theory of mineral resource strategy, the industrial development status, future demand, resource potentiality and support, environment capability of bauxite resources in Henan province, and resource utilization by Henan in other provinces and abroad are comprehensively studied and analyzed in this thesis.Through the study on the industrial development of bauxite resource, it is concluded that the aluminum industry of Henan still develops with a high speed and superiority to other provinces. However, the support period of proved bauxite resource is short. The recoverable basic reserve of bauxite in Henan is about 696.4 million at present. This reserve is amount to exploited ore of about 216.4 million tons and the static support period of this reserve is shorter than 9 years, which is in severe resource-shortage. Moreover, the input of bauxite exploration has declined in recent years and deep-seated ore prospecting is also not carried out. The bauxite, with high-sulfur content but low grade, covers 20% of the total bauxite resource of Henan. Civilian exploitation is common and the recovery rate is lower than 60%. Through the study on the future demand for bauxite resource in Henan, following conclusions are obtained. Henan is in the middle and late period of industrialization and is in badly need of mineral resources especially bauxite. The demand peak for bauxite would be in the coming ten years. For seek of keeping the superiority of aluminum industry of Henan to the other provinces, bauxite of 377 million tons in grand total is needed in the coming ten years. Through the study on the potentiality of bauxite of Henan, following conclusions are made. Henan has a favorable mineralization condition for bauxite and bauxite-containing rock is widely distributed (covering an area of about 20,000km2). The superficial bauxite (with a depth of 150-300m underground) is mostly proved but those in medium and deep earth (with a depth of 300-1000m underground) are rarely prospected. Therefore, there is still a great room for the exploration of bauxite in middle and deep earth. Potentiality prediction has been made to the medium and deep part of the thirteen potential areas of bauxite metallogenic areas with high possibility of exploration. In these areas, 440 million tons of potential bauxite reserves, equal to 220 million tons of recoverable reserves, is obtained. During the study on the support of bauxite, following ideas are obtained. The establishment of sustainable supply strategy of bauxite should conform to the theory of mineral resource consumption and provide resource support dynamically, namely, increase supply during consumption peak season and decrease supply during consumption slack season. The bauxite mineral recourse can meet the dynamic demand for ten years. Through the study on the resource utilization by Henan in other provinces and countries and the environment capability of Henan, it is concluded that there are still much room in using bauxite both in other provinces and countries and the environment capability of Henan is under control.Based on the above study, the mineral resource strategy for the sustainable development of aluminum industry is put forward. Several specific measures are put forward too, namely, carry out new geological exploration as soon as possible, improve recovery rate, and make full use of two markets and two kinds of resources.更多还原
