摘要
以提高煤炭资源回收率、保证安全生产、企业效益最大化为原则,结合矿井煤层赋存特点,坚持高起点、高技术、高效率、高效益的发展方针,合理利用现有回采设备配置,对特厚煤层顶煤冒放性进行研究,提高煤炭资源回收率,确保矿井实现高产、高效和安全生产。
Based on the principle of improving the recovery rate of coal resources,ensuring the safety of production and maximizing the benefits of enterprises,combined with the characteristics of coal seam occurrence in the mine,adhering to the development policy of high starting point,high technology and high efficiency,the paper studies on the caving of top coal in extra thick coal seam by making rational use of the existing mining equipment configuration,which improves the recovery rate of coal resources and ensures high production,high efficiency and safety production of the mine.
