    This technique, most commonly used in longwall mining in the United States, is relatively new and it differs from European systems in several ways. US coal seams are generally thin, shallow, and relatively more permeable. Typically, only one seam is mined in a given area and retreat longwall mining is the only method being practiced at present.

    Historically, room-and-pillar mining has dominated coal production, and this mining method has been the focus of most multiple-seam research. Advances in Longwall Mining Method have made this system more economically attractive because of its efficiency and production potential.

  • Longwall Mining Overview Introduction

    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.

    Starting around 1900, mechanization was applied to this method. By 1940, some referred to longwall mining as "the conveyor method" of mining, after the most prominent piece of machinery involved. Unlike earlier longwall mining, the use of a conveyor belt parallel to the coal face forced the face to be developed along a straight line.
