Surface and Underground Coal Mines in the U.S.

Surface and Underground Coal Mines in the U.S. This feature layer, utilizing data from the Energy Information Administration (EIA), displays all operating surface and underground coal mines in the U.S. by total production in short tons. Per EIA, “Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.” Coal is mainly found in three regions: the Appalachian coal region, the Interior coal region, and the Western coal region (includes the Powder River Basin). The Appalachian coal region includes Alabama, Eastern Kentucky, Maryland, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia. The Interior coal region includes Arkansas, Illinois, Indiana, Kansas, Louisiana, Mississippi, Missouri, Oklahoma, Texas, and Western Kentucky. The Western coal region includes Alaska, Arizona, Colorado, Montana, New Mexico, North Dakota, Utah, Washington, and Wyoming.

美国露天与地下煤矿数据集。本要素图层依托美国能源信息署（Energy Information Administration, EIA）公开数据，展示美国境内所有在运营露天及地下煤矿按短吨（short ton）统计的总产量情况。据EIA官方定义："煤炭是一种可燃黑色或深棕黑色沉积岩，富含碳与烃类物质。因其形成需历经数百万年，故被归类为不可再生能源。煤炭储存着数亿年前沼泽森林中植物所固定的能量。"煤炭主要分布于三大煤田区域：阿巴拉契亚煤田、内陆煤田与西部煤田（涵盖粉河盆地）。其中阿巴拉契亚煤田覆盖阿拉巴马州、东肯塔基州、马里兰州、俄亥俄州、宾夕法尼亚州、田纳西州、弗吉尼亚州及西弗吉尼亚州；内陆煤田覆盖阿肯色州、伊利诺伊州、印第安纳州、堪萨斯州、路易斯安那州、密西西比州、密苏里州、俄克拉荷马州、德克萨斯州与西肯塔基地区；西部煤田覆盖阿拉斯加州、亚利桑那州、科罗拉多州、蒙大拿州、新墨西哥州、北达科他州、犹他州、华盛顿州与怀俄明州。Gemini露天煤矿数据时效性说明：本Esri缓存服务每月会从其联邦数据源（Coal Mines）同步更新一次。数据修改说明：无。如需获取更多详情，请访问《煤炭详解》（Coal Explained）。反馈渠道：[e-mail]。美国能源信息署。另据EIA官方说明："美国能源信息署（EIA）负责收集、分析并发布独立公正的能源信息，以助力科学决策、高效市场运行，并提升公众对能源及其与经济和环境互动关系的认知。"
