Planned Coal Mine Subsidence in Illinois

high-extraction mining methods, such as longwall, in areas where it has the right to subside the ground surface. Planned subsidence using the longwall mining method enables Illinois coal mine operators to maximize mining productivity and decrease the per ton cost of the delivered product, thus improving coal's marketability. Also,

Longwall Mining In Illinois - onemine.org

INTRODUCTION In June 1962, the first attempt at longwall mining in Illinois was initiated by Old Ben Coal Company in their No. 21 Mine. Longwalling was continued intermittently using various supports until April 1970. During this period, longwall mining techniques were used on separate occasions at six faces within Mine No. 21.

Longwall Mining Overview | Introduction | underground COAL

LONGWALL MINING Overview. In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face.

Longwall mining - SourceWatch

Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 1-2 m thick). The longwall "panel" (the block of coal that is being mined) is typically 3-4 km long and 250-400 m wide. Longwall mining produced 176 million tons of coal in 2007, about 15 percent of total U.S. production.

The longwall face is indicated by the number 8 in the diagram. Fig. 1.1 Cutaway View of a Typical Longwall Mine In longwall mining, a panel of coal, typically around 150 to 300 metres wide, 1000 to 3500 metres long and 2 to 5 metres thick, is totally removed by longwall shearing machinery, which travels back and forth across the coalface.

DIRECTORY OF COAL MINES IN ILLINOIS

High-extraction retreat mining is a form of room-and-pillar mining that extracts most of the coal. Rooms and pillars are developed in the panels, and the pillars are then systematically removed (fig. 1F). In early (pre-1960) longwall mines, mining advanced in multiple directions from a central shaft (fig. 1G).
