摘要
北京市矿产资源利用现状调查,查明了北京市煤、铁、锰、铜、铬、铅、锌、铝土、钨、钼、金、银、硫铁矿、萤石、饰面用大理岩、水泥用灰岩共计16个矿种的核查任务,最终形成了140个上表核查单元。通过分析核查前后资源储量变化情况,总结了11类变化原因:未上表矿区纳入、漏上表、错误上表、重复上表等等。文章通过分析对比,查明了核查前后资源储量的变化原因,提高了核查结果的可信度,为北京市矿产资源利用现状调查成果与矿产资源储量数据库衔接,提供了可靠的基础资料。为北京市矿政管理,提供了扎实的基础数据支撑。
Through the survey on the mineral resources utilization in Beijing, the reserves verification task on 16 kinds of minerals is finished, such as coal, iron, manganese, copper, chromium, lead, zinc, bauxite, tungsten, molybdenum, gold, silver, pyrite, fluorite, ornamental marble, cement limestone, eventually 140 on-sheet verification units are listed out. By analyzing the reserves changes before and after verification, there are 11 categories of reasons for the changes: the standard is not uniform whether to be listed on sheet for some mineral resources; some resources are missed or duplicated to be listed on sheet etc. By analysis and comparison, we find out the reasons for the changes of the reserves before survey and after, and improve the credibility of the results of the survey, provide a reliable basis of information for Beijing mineral resources use survey results and reserves of mineral resources database convergence, and provide a solid foundation data support for mining management in Beijing.
