摘要
河南省是我国重要的铝工业基地之一,氧化铝产量约占全国的三分之一,铝土矿潜在资源总量约14亿吨,累计查明储量4亿吨以上,但当前浅部铝土矿资源勘探已基本完成,资源开发亦接近尾声,矿山企业面临资源保障后继无力的风险。在新一轮找矿突破战略行动中,如何通过开展深部铝土矿资源勘查、采矿证范围内空白区域勘探或扩深增储以及煤下铝勘查,多途径实现资源增储,成为当下之急。本文通过对河南省豫西铝土矿的成矿规律、地质特征以及找矿标志分析,构建找矿模型,结合三维技术,进行勘探验证与资源评估,综合预测矿体分布走势,精准选择成矿潜力大的靶区,有效提高河南省铝土矿的找矿成功率和资源储量估算的准确性,并对煤下铝土矿勘查进行了分析,为后续的铝土矿资源获取和矿山可持续开发提供科学依据和技术支撑。
Henan Province is one of the important aluminum industry bases in China,with alumina production accounting for about one-third of the country's total.The total potential resources of bauxite are about 1.4 billion tons,and the cumulative confirmed reserves are over 400 million tons.However,the exploration of shallow bauxite resources has been basically completed,and resource development is also nearing its end.Mining enterprises are facing the risk of insufficient resource guarantee.In the new round of strategic breakthroughs in mineral exploration,it is urgent to explore deep bauxite resources,explore blank areas within mining permits or expand reserves,and explore aluminum under coal through multiple channels to increase resource reserves.This article analyzes the mineralization laws,geological characteristics,and prospecting indicators of bauxite in western Henan Province,constructs a prospecting model,combines 3D technology for exploration verification and resource evaluation,comprehensively predicts the distribution trend of ore bodies,accurately selects target areas with high mineralization potential,effectively improves the success rate of bauxite prospecting and the accuracy of resource reserve estimation in Henan Province,and analyzes the exploration of bauxite under coal,providing scientific basis and technical support for the subsequent acquisition of bauxite resources and sustainable development of mines.
