Deposit Type

  • Sedimentary


Summary:

The coal reserves reported herein are typically low-volatile bituminous coals which exhibit metallurgical coal characteristics. The primary coal-bearing formations on these Properties are of the Pennsylvanian System of the Carboniferous Period, and are part of the Pottsville Formation. The average seam thickness for coal horizons in these formations ranges from less than 1 foot to more than 5 feet. Within the subject Properties, coal zones can locally exceed 10 feet where individual coal beds merge to form a single mineable unit. Coal reserve deposits on the Properties average approximately 1,700 in depth below the surface of the Properties. Structurally, the strata form a homocline that exhibits a regional northwest-southeast strike and a regional southwestward dip of less than one percent. The seams are continuous across much of the Properties with complex zones of offset due to faulting. Seams generally retain normal stratigraphic sequences and are rarely modified from predeformational thickness.

Mineable coal beds within the subject Properties are typically low-ash, low-sulfur, highthermal content, and low-volatile bituminous coals. Although maximum seam thickness may reach over 10 feet, the seam thickness of the mineable zones in this evaluation generally averages 4.5 to 5.0 feet. These mineable zones include the Mary Lee and Blue Creek seams which define the coal reserves that are presented herein. These seams are present and continuous across the entirety o ........


Mining Methods

  • Continuous
  • Room-and-pillar


Summary:

The metallurgical coal is mined using longwall extraction technology with development support from continuous miners. Mine No. 7 - underground operation with two longwall systems.

The mining plan at the No. 7 Mine incorporates continuous and longwall underground mining methods similar to the No. 4 Mine, however there is a change in the mineable seam horizon. The Blue Creek seam and the Mary Lee seam are further apart as the middleman thickness increases to several feet in the No. 7 Mine area. The Blue Creek seam is the primary focus of the longwall mining operation. The Mary Lee seam which lies several feet above the Blue Creek is not mined unless it facilitates roof support for long term stability as in the Main developments which must remain stable for the life of all the longwall panels in a reserve area. The Blue Creek seam is being mined at a depth ranging from approximately 1,500 to 2,000 feet. The Blue Creek seam is suitable for metallurgical purposes and as a compliance steam coal.
