数据的背后——北京市铁矿资源战略储备浅析

Invisible data — a brief analysis of iron ore resources as strategic reserve in Beijing

北京市铁矿矿山于2020年底前陆续关闭,铁矿资源全部转为战略储备。北京市铁矿资源国情调查工作对铁矿资源储备进行了分类汇总。数据表明,北京市铁矿资源战略储备丰富。但数据背后隐藏着可变因素,致使数据质量下降。相关信息分析表明,数据可变因素可归结为由资源禀赋自身引起储量变化的内在因素和从地表或浅部改变矿产资源储量或赋存状态的外在因素。数据可变因素同应急启用的限制条件一起,共同制约着战略储备的未来可利用性。战略储备应急启用的主要方向遂水落石出。

Iron mines in Beijing had all been closed before 2020 and the remaining iron ore resources as a whole consequently stay as strategic reserve. The national survey work on iron ore resources in Beijing summarized the related data by category. The data shows that as a strategic reserve, Beijing ’ s iron ore resources are abundant. However, invisible and variable factors exist which can result in poor data quality. These factors can be further divided into the following two groups: an internal cause,termed as resource endowment, which can make changes in the amount of iron ore reserves;an external cause, which can make changes in reserves as well as in the hosting conditions of iron ore on the surface or in the shallow part of the mining area. In addition to variable factors, there are other negative ones that influence the future exploitation of the resources. Accordingly, the main direction for the strategic reserve exploitation in case of need is identified.
