浅谈如何提高综采放顶煤工作面回采率

Discussion on How to Improve the Working Face Recovery Rate of Fully Mechanized Top Coal Caving

综采放顶煤开采法较适用于开采中厚煤层,特别是厚煤层开采,其具有高产、高效、低耗等优点,但也存在缺点,即工作面回采率低。为提高综采放顶煤工作面回采率,在介绍综采放顶煤工艺流程的基础上,分析煤炭损失原因,提出提高放顶煤开采回采率的措施,以供同行参考。

Coal mining method for fully mechanized top coal caving is suitable for mining thick coal seam, especially thick coal seam mining. It has the advantages of high yield, high efficiency and low consumption. But there is drawback, that is, the working face recovery rate is low. In order to improve the recovery rate of working face, this paper analyzed the causes of coal loss on the basis of introducing the process flow of fully mechanized top coal and put forward measures to improve the recovery rate of coal mining for peer reference.
