摘  要：传统的综采工作面大跨度切眼施工期间，通常采用单体支柱配合π型钢梁加固顶板，顶板支护效果差，效率低下，且安全隐患较大。针对综采工作面切眼大跨度顶板支护难题，采用顺山液压支架加固顶板施工工艺，取得较好的支护效果。

Abstract： During the long-span cut-off construction of traditional fully mechanized mining face， single pillar combined with π-shaped steel beam is usually used to reinforce the roof， which leads to poor support effect， low efficiency and large safety risks. Aiming at the problem of large-span roof support in fully mechanized mining face， this paper adopts the construction technology of hydraulic support to strengthen the roof， and a good supporting effect has been obtained.

Keywords： large-span cut; roof support; hydraulic support; construction technology; support effect

传统的综采工作面切眼施工是在导硐切眼形成的前提下，沿导硐切眼方向对导硐切眼进行刷扩作业，通过增大切眼跨度以满足综采液压支架安装的空间需要。（剩余4962字）
