Abstract:

Coal mining has occurred in Pennsylvania for over a century.  A method of coal mining known as Longwall Mining has become more prevalent in recent decades.

Longwall mining involves cutting the coal off the face of a long wall panel of coal in a single pass of the machinery. The machinery will then advance forward and perform another pass along the coal face. The broken off coal is hauled to the surface using conveyor belts. As the machinery advances forward into the coal panel, the mine roof is allowed to collapse behind it.

This dataset identifies the footprint of these longwall panels relative to the surface.

Purpose:

The purpose of this dataset is to identify the footprint of longwall panels relative to the surface.

Supplemental_Information:

This data is intended for use at 1:24,000 or smaller scale.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Several attributes contain details of mine names, operators, status, and other details of mining operations.  These mine names, operators, status, and other details of mining operations change over time and there is NO guarantee that the data listed is the most accurate, recent, and/or complete.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

This dataset was created by digitizing georeferenced mine maps of various/unknown accuracy and various/unknown coordinate systems to various base maps, including but not limited to USGS topographic maps and PAMAP aerial photography. Therefore horizontal accuracy of the polygons representing the longwall panel footprints are UNKNOWN.

Lineage:

Source_Information:

Source_Contribution:

This dataset was created from digitizing mine maps developed from multiple mine operators.  Credit should be given to the mine operators for developing the original mine maps.

Process_Step:

Process_Description:

This dataset was created by scanning mine maps submitted to the Pennsylvania Department of Environmental Protection (DEP) as part of the Application for Bituminous Underground Mine or part of a six month mine map update required under the permit.  Various scanners were used at different locations at different times. Once a map was scanned, most of the electronic images were post-processed using Adobe Photoshop CSx, to reduce the overall file size to a manageable size to allow our computers to display them efficiently. Some of the processes performed on the images include grayscaling, image size reduction, cropping, and autocontrasting. Once the images were a managaeble size, they were georeferenced using ArcGIS to base maps, including but not limited to 7.5 minute USGS topographic maps and PAMAP aerial photography. Next, the longwall panel footprints on the map image were digitized and attributed.
