Surface Mining (Past and Current)

Surface Mining Areas denote an area of coal extracted by surface excavations in the past or are being excavated currently, these sites do not necessarily reflect the extent of the excavation. Coal resources may still be available within these areas due to the inefficiencies of some historic mining techniques. These areas are often referred to as “opencast mining”. Together with the Surface Coal Resource Area data, provide information to Mineral Planning Authorities for assisting in defining Mineral Safeguarding Areas in policy strategy.露天采矿区（Surface Mining Areas）指过往或当前通过露天采掘作业开采煤炭的区域，此类区域未必与实际采掘范围完全重合。由于部分历史采矿技术效率低下，该区域内可能仍留存有可开采煤炭资源。这类区域通常也被称为‘露天开采（opencast mining）’。本数据集与露天煤炭资源区（Surface Coal Resource Area）数据相结合，可为矿产规划主管部门提供相关信息，辅助其在政策战略框架内划定矿产资源保护区（Mineral Safeguarding Areas）。
