这些数据的4.0版是美国地质勘探局一个更大的项目的一部分，该项目旨在开发一个更新的美国矿山、矿藏和矿产地的地理空间数据库。与地雷和探矿有关的符号，例如用于表示探矿坑、地雷、凹坑、垃圾场、尾矿等的符号，以下称为“地雷”符号或特征，目前正在从美国地质调查局历史地形图收藏的7.5分钟(1：24 000比例尺)和15分钟(1：48 000和1：62 500比例尺)档案中逐个州进行数字化，或从现有的数据库中获取(仅加利福尼亚州和内华达州，1：24 000比例尺)。这些要素的汇编是获取美国各地矿产资源勘探和开采相关要素的准确位置和一般信息的第一阶段。到目前为止，来自35个州约88,000张地图的637,000多个点和面矿符号的汇编工作已经完成：阿拉巴马州(AL)、亚利桑那州(AZ)、阿肯色州(AR)、加利福尼亚州(CA)、科罗拉多州(CO)、佛罗里达州(FL)、佐治亚州(GA)、爱达荷州(ID)、爱荷华州(IA)、伊利诺伊州(IL)、印第安纳州(IN)、堪萨斯州(KS)、肯塔基州(KY)、路易斯安那州(LA)、密歇根州(MI)、明尼苏达州(MN)、密西西比州(MS)、密苏里州(MO)、蒙大拿州(MT)、北卡罗来纳州(NC)、北达科他州(ND)、内布拉斯加州(NE)、新墨西哥州(NM)、内华达州(NV)、俄克拉何马州(OK)、俄亥俄州(Ohio)、俄勒冈州(OR)、南卡罗来纳州(SC)、南达科他州(SD)、田纳西州(TN)、德克萨斯州(TX)、犹他州(UT)、华盛顿州(WA)、威斯康星州(WI)和怀俄明州(Wyming)。这一过程不仅提供了美国勘探和采矿的更完整的图景，而且提供了这些活动发生的大致时间线。这些数据可用于土地利用规划、评估废弃矿场和与采矿有关的环境影响、评估来自联邦、州和私有土地的矿产资源价值，以及绘制矿化区和系统图，以便为土地管理进程提供投入。数据根据源地图的比例显示为三组图层。数据组之间没有进行任何对账。
Version 4.0 of these data are part of a larger USGS project to develop an updated geospatial database of mines, mineral deposits and mineral regions in the United States. Mine and prospect-related symbols, such as those used to represent prospect pits, mines, adits, dumps, tailings, etc., hereafter referred to as “mine” symbols or features, are currently being digitized on a state-by-state basis from the 7.5-minute (1:24,000-scale) and the 15-minute (1:48,000 and 1:62,500-scale) archive of the USGS Historical Topographic Maps Collection, or acquired from available databases (California and Nevada, 1:24,000-scale only). Compilation of these features is the first phase in capturing accurate locations and general information about features related to mineral resource exploration and extraction across the U.S. To date, the compilation of 637,000-plus point and polygon mine symbols from approximately 88,000 maps across 35 states has been completed: Alabama (AL), Arizona (AZ), Arkansas (AR), California (CA), Colorado (CO), Florida (FL), Georgia (GA), Idaho (ID), Iowa (IA), Illinois (IL), Indiana (IN), Kansas (KS), Kentucky (KY), Louisiana (LA), Michigan (MI), Minnesota (MN), Mississippi (MS), Missouri (MO), Montana (MT), North Carolina (NC), North Dakota (ND), Nebraska (NE), New Mexico (NM), Nevada (NV), Oklahoma (OK), Ohio (OH), Oregon (OR), South Carolina (SC), South Dakota (SD), Tennessee (TN), Texas (TX), Utah (UT), Washington (WA), Wisconsin (WI), and Wyoming (WY). The process renders not only a more complete picture of exploration and mining in the U.S., but an approximate time line of when these activities occurred. The data may be used for land use planning, assessing abandoned mine lands and mine-related environmental impacts, assessing the value of mineral resources from Federal, State and private lands, and mapping mineralized areas and systems for input into the land management process. The data are presented as three groups of layers based on the scale of the source maps. No reconciliation between the data groups was done.
