Figures 2-9: Barrier Pillars in the Western Middle Field: Anthracite Region of Pennsylvania

Maps illustrating an investigation of barrier pillars in the Western Middle field as part of the comprehensive study of mine-water problem in the anthracite region of Pennsylvania. Scale 1:4,500 feet. Included in the set is a graph (Figure 8) showing the relationships between pumping loads in the anthracite region of Pennsylvania with altitude on the x-axis and distance (in miles) from the Conowingo Portal on the y-axis. An explanation of the graph in Figure 8 (Figure 9) summarizes data from Bureau of Mines Technical Paper 727, Report of Investigations 4700, and Bulletin 513.

Method and Cost of Mining the Thick Freeport Coal in a Second Western Pennsylvania Mine (open access)

Method and Cost of Mining the Thick Freeport Coal in a Second Western Pennsylvania Mine

From introduction: The purpose of this paper is to present a detailed description of the methods employed and the equipment used, with the results obtained in the operation of this mine in the thick Freeport bed on the northern end of the field, near the Alleghegny-Butler county line in western Pennsylvania. It may be classed as a captive mine, as the largest portion of the product is consumed at the by-product plants of the parent company

Field Demonstration of Two Pneumatic Backfilling Technologies (open access)

Field Demonstration of Two Pneumatic Backfilling Technologies

Abstract: This U.S. Bureau of Mines (USBM) report summarizes a field demonstration of pneumatic backfiling technologies conducted at the abandoned Hillside Coal and Iron Slope in Vandling, PA. Researchers demonstrated tro pneumatic backfilling technologies recently developed under the USBM's Abandoned Mine Reclamation Research Program, the Pneumatic Pipefeeder and the High-Efficiency Ejector. Both systems had previously been evaluated at the USBM's subsidence abatement investigation laboratory near Fairchance, PA. The objective of the demonstration was to fill 100% of the abandoned tunnel with backfill stone to prevent further subsidence. The Pneumatic Pipefeeder was used for 21 days, at a rate of 63 to 124 t/d (69 to 136 st/d), to fill 88% of the tunnel. The High-Efficiency Ejector was used for 2 days, at a rate of 125 to 132 t/d (138 to 146 st/d) to fill the remaining 12% of the tunnel. The backfill placed by both systems was tightly compacted. The major problem encountered was wear on the polyethylene pipeline from the abrasion of the high-velocity backfill. The use of heavier steel pipe minimized the problem. A cost analysis for the entire project is given.
