摘要
煤层直接顶板稳定程度的差异,其根本原因在于地质条件的差异。煤层顶板的岩性是影响煤层顶板稳定性的重要因素。深入研究煤层顶板的地质条件,是管理好回采工作面煤层顶板的关键。
The difference of stability degree at the immediate roof in coal seam, the fundamental reason lies in differences in geological conditions.The lithology of coal seam roof is an important factor of influencing on the stability of coal seam roof. Research in depth on geological conditions of the coal seam roof is a key of managing the coal seam roof at the coal face.
