No country in the world produces all of the mineral resources necessary for modern society. International trade plays a critical role in providing these raw materials, forming a global network of production, export, import, and use. This network must continuously adapt to national and international developments in science, technology, politics, and economics. As a result, information on the global flow of raw materials plays a fundamental role in improving national and international resilience to potential supply disruptions and market changes.
The Kentucky Mine Mapping Information System is produced by the Kentucky Energy and Environment Cabinet to allow users to access maps of coal mines and mined out areas in Kentucky. Users can search by company name, seam name, or state file number (SFN). For each map, overview information is provided where available (map year, mine status, mine owner, mine type, seam thickness, etc.), and users are directed to the map. Users can also overlay information on oil and gas activity on the map.
The Minnesota Department of Natural Resources provides an interactive map of underground mines in Minnesota. The map provides detailed information on underground mines and their relationship to overlying surface features. Specifically, this map focuses on iron mines in the northeast of the state.
The North Dakota Public Service Commission provides an interactive map showing the locations of known abandoned mines in North Dakota. Users can click on an individual mine for more information, including the type of mine and the amount of information available for each mine.
Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals.
