特厚煤层综放工作面顶煤运移规律研究

Study on Top Coal Movement Rule of Fully Mechanized Caving Face in Extra-Thick Coal Seams

本文通过对9-101综放工作面顶煤运移规律的实测,结合特厚煤层综放工作面顶煤运移以及破坏规律的分析,得出在此条件以及相似条件下特厚煤层综放工作面顶煤运移规律,为综放工作面提高采出率以及液压支架工作阻力的确定提供依据。

Based on the measurement of top coal movement of the 9-101 fully mechanized caving face and the analysis of top coal movement and failure law in extra-thick coal seams,the top coal migration law of fully mechanized caving face under these conditions or similar conditions is obtained,which provides the basis for improving the recovery rate of fully mechanized caving face and determining the working resistance of hydraulic support.
