Title:

Active Underground Coal Mine Map Mosaic [Pennsylvania] {2024}

Description:

The Active Underground Coal Mine Map Mosaic map service is an imagery composite of georeferenced underground coal mine maps of mining operations currently or recently in active status in Pennsylvania. When viewing detailed mine workings depicted on the maps in areas where multiple mines exist adjacent to each other, parts of one map may overlap, obstructing the view of adjacent maps. Through the mosaic process, the irrelevant parts of a map are cropped, so that the maps edge-match without overlap, creating a near seamless image of underground mine workings. Pennsylvania state law requires those who wish to conduct mining activities within the Commonwealth submit and get approval by the Pennsylvania Department of Environmental Protection (DEP) for permits related to those activities. Every six months, operators must submit an Exhibit 22.6 Six-Month Subsidence Map that shows which areas inside their approved permit boundary have been mined in the previous six-month period and where the operator plans to mine within the permit boundary in the following six-month period. “Six-month” map submittal schedules from the various mine operators are spread out through the year. Review and approval of these “six-month” maps by DEP can take varying amounts of time depending on the complexity of each individual permit. “Six-month” maps are updated and added in the mosaic only after they are approved by DEP. Therefore, the timeframe of the depicted mine workings on the mosaiced maps may vary across the individual mine permits. There is an inherit loss of accuracy in the georeferencing process and a georeferenced map may not align correctly with base maps and/or established coordinate systems. Therefore, these georeferenced maps should ONLY be used for reference information only and NOT be used for engineering and/or human safety related issues. Uncropped, individual georeferenced maps can be viewed on the Pennsylvania Mine Map Atlas at www.paminemaps.psu.edu . Detailed metadata on the individual maps can be found in the Pennsylvania Historic Underground Mine Map Inventory System (PHUMMIS) at www.PHUMMIS.pa.gov .
