针对“三软”煤层机采工作面机头机尾处围岩变形量大的特点,研发了适用性能强的端头步移式支护架,分析了步移式支护架主要特征及其控制移架原理。通过工作面应用实测研究,得到步移式支护架上支架载荷及围岩顶底板移近量,步移式支护架对“三软”煤层端头处大变形起到了很好的控制。
針對“三軟”煤層機採工作麵機頭機尾處圍巖變形量大的特點,研髮瞭適用性能彊的耑頭步移式支護架,分析瞭步移式支護架主要特徵及其控製移架原理。通過工作麵應用實測研究,得到步移式支護架上支架載荷及圍巖頂底闆移近量,步移式支護架對“三軟”煤層耑頭處大變形起到瞭很好的控製。

According to"three soft"coal seam face end up and down‘s surrounding rock deformation characteristics and the requirements of the supporting structure, developed a strong applicability of the end step type supporting frame, analyzes the main features and control step type supporting frame shift theory. Through the research on the application of working face are measured, step type supporting frame on the load of support and surrounding rock roof-to-lfoor convergence, step type supporting frame of"Three Soft"coal seam end deformation played a very good control.
