河南省铝土矿资源潜力与发展战略研究.doc

河南省铝土矿资源潜力与发展战略研究 河南省铝土矿资源丰富,主要分布在三门峡-郑州-平顶山之间的三角地带,含矿系分布面积达3万平方公里。以铝为主的有色金属工业是河南省的支柱产业之一,河南省铝土矿资源储量居全国第三位,氧化铝、电解铝产量居全国第一。河南省具有发展铝工业的资源、能源和产业优势,年消耗铝土矿储量约3300万吨,资源供给保障能力不足已成为铝工业发展的约束环节。论文采用可持续发展理论、资源经济学、资源战略、产业结构合理化理论等,系统研究了河南省铝土矿资源可持续发展战略,从七个方面提出了解决河南省铝工业资源约束问题的对策和建议。重点从矿产资源全球配置的角度,分析了“走出去”利用海外资源存在的机遇和挑战、利用境外资源的必要性和可行性;提出了利用海外资源应采取国家调控、企业为主体、资源来源及利用方式多元化的原则;采用贸易进口、境外勘查开发并举,多元化、多渠道、多方式利用境外铝土矿产资源,确保河南省铝工业持续、健康发展。论文对河南省七个重要铝土矿成矿区带进行了找矿潜力分析。根据成矿地质条件、铝土矿床分布和勘查工作程度、矿体特征等因素,结合已知勘查区周边和深部找矿潜力,划分了三类67个成矿预测区,并确定了预测区范围区间、矿体厚度、体重、面含矿系数等预测参数,预测估算300米以浅铝土矿334类资源量99285万吨。综合分析了各预测区勘查和开发条件,优选38处可望提交经济可采资源储量的找矿靶区,估算了经济可采资源量,对河南省铝工业的发展现状,制约因素,以及在全国所处的位置进行了科学分析,提出了河南省铝土矿资源勘查开发和铝工业可持续发展的战略规划。;ReplaceFontEnDivSummary,Henan is abundant in bauxite resources, which mostly distributes in those inverted triangle zone around Sanmenxia-Zhengzhou-Pingdingshan, the total ore-bearing area can be 30,000 Square kilometers. Most bauxite resides in diaspore type of sedimentary deposit, of Carboniferous stratum, Benxi group, characterized by large scale, good quality high in aluminum and silicon, low in iron, fine mining condition, and considerable reserve for open-pit mining and there’re other associated components thus can be utilized jointly. Aluminum-based non-ferrous metals industry is a pillar industry in Henan, whose bauxite reserve ranked third in China, also, its alumina and electrolytic aluminum output ranked top in the country. Henan is endowed its advantage in developing aluminum industry. Hence, aluminum industry in Henan will keep on growing rapidly, with an annual consumption of bauxite reserves of about 33 million tons. Estimated from the current situation, bauxite resources can only be self-supplied for 7 years. Inadequate supply insurance has badly constrained the development of aluminum industry in Henan.By using sustainable development, mineral resources economics, and other theory.after thorough investigation of Henan’s sustainable development strategy, we recommend several measures and solutions to handle with the aluminum restriction of Henan . Focusing on globe allocation of mineral resources, we analyzed opportunities and challenges as well as the necessity and feasibility faced by the “going out“ policy---utilization of overseas resources; we should adopt a discipline that under the government’s regulation and coordination, whereas enterprise serves as the main body, with sources and approaches of resources diversified. In specific, we should take both means of imports and overseas exploration simultaneously, to develop overseas bauxite resources in a diversified, multi-use and multi-channel way. The key areas should be countries to the south of China, such as Vietnam, Malaysia, Indonesia, ect.We’ve done a lot of work in those prospect areas within the 7 most important metallogenic regions in Henan, and then we uated the mineralization potential. Furthermore, referred to exploration potential in peripheral and deep parts of the known area, according to their geological background, location of bauxite deposits, the exploration level and the feature of ore body, we classify them into 3 types, 67 metallogenic prognosis region, we determined those prediction parameters, such as the range of forecast area, ore body thickness, body weight, ore-bearing coefficient on the surface. Then we came up with estimation that within 300 meters from the top, the reserve could be expected to 992,850,000 ton 334, according to the national standard of reserve classification. Take the respective prospecting and exploration condition in consideration, we put forward 38 target areas that’s most likely to be economic feasible, and gave out a estimation of economic recoverable reserves and suggestions in the next step.;
