LGRB-BW RAW: Processed area

Since 1986, the LGRB has operated a standardised operational survey of mining sites of near-surface mineral raw materials in the country. Since the beginning of 2004, this task has been operated as a raw material extraction point database (RGDB) in cooperation with the regional associations. The topic shows the current extraction points of the RGDB and selected attributes.自1986年起，LGRB便在该国开展近地表矿物原料矿区的标准化作业勘查。自2004年初起，该项工作与各区域协会协同开展，以原料开采点位数据库（RGDB）的形式运行。本数据集主题涵盖RGDB当前的开采点位及部分选定属性。
