THE GENERAL RULES OF FOSSIL WEATHERED RESIDUUM IN MINING AREA AND MECHANISM OF CUTTING WATERPROOF COAL PILLAR

    Graphical Abstract
    • Abstract
  • Through detailed research on the data of fossil weathered residuum in Huang and Huai coal mining area,the zone of high-weathering has been divided simply.The author studies mainly on the characteristics of engineering geology about the zone of weathering overlying coal seam,the mechanism of cutting waterproof coal pillar and provides the reference for the coal mine with similar condition in cutting waterproof coal pillar.
