摘要: 以霍宝干河煤矿1301 工作面为研究背景,通过矿压观测,确定了工作面超前支承压力范围以及塑性破坏区
域。通过对回采巷道以及开切眼进行加强支护,有效控制了巷道围岩的变形。单体液压支柱的支护,减少了由顶板断裂
造成的下沉现象,满足了回采要求。

Abstract: Taking 1301 working face of Huobaoganhe Coal Mine as the research background, through mine pressure observation,
the advanced supporting pressure range and plastic failure area of the working face were determined. The surrounding rock
deformation of the roadway was effectively controlled by strengthening the support of the mining roadway and the open cut. The
supporting effect of the single-body hydraulic support reduced the sinking phenomenon caused by the roof fracture, which met the
mining demand.

Key words: mine pressure observation; advanced supporting pressure; plastic failure area; strengthening support
