  • Coal Mining Methods.edu

    Longwall mining and room-and-pillar mining are the two basic methods of mining coal underground, with room-and-pillar being the traditional method in the United States. Both methods are well suited to extracting the relatively flat coalbeds (or coal seams) typical of the United States. Although widely used in other countries, longwall mining ...

    But virtually no improvements have been made in dust control on longwall sections. It is true, that there are many more continuous mining sections than longwall sections in the United States and that the number of workers overexposed on continuous miner sections is much larger than the number on longwall sections.

  • Longwall cutter drum having reduced production of dust ...

    In longwall mining, a significant portion of the shearer operator's dust exposure is caused by dust generated during loading. With the conventional direction of shearer drum rotation, loading efficiency is usually poor due to obstructions caused by the ranging arms and the cowl support arms.

  • Longwall Mining – Mining Science and Technology

    Longwall mining activities alter the exsisting ground stress field, this changed stress field is known as induced stress. Extraction of coal by longwall mining induces a redistribution of stresses causing the rocks near the mining excavation to accomodate a redistributed load. Effective and efficient longwall mining is dictated by the [.]
