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。During the long-span cut-off construction of traditional fully mechanized mining face,single pillar combined withπ-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.

关 键 词：大跨度切眼 顶板支护 顺山支架 施工工艺 支护效果
