摘　　要：通过单体铰接梁超前支护与自移式支架超前支护的技术特征分析和现场矿压观测试验,比较了两种支护形式下围岩变形规律,结果表明,采取超前自移支架支护减少了巷道顶底板及两帮的移近量,支护效果好。By the technical characteristics analysis and mine pressure observation of the advanced supporting by single hydraulic prop or self-moving advanced hydraulic support,the deformation law of surrounding rock in the two supporting forms was compared. The result shows that the supporting scheme of self-moving advanced hydraulic support can reduce the displacement of roadway and achieve good supporting effect.

关 键 词：自移式超前支架 单体支护 深井厚煤层工作面
