摘  要：傳統(tǒng)的綜采工作面大跨度切眼施工期間，通常采用單體支柱配合π型鋼梁加固頂板，頂板支護(hù)效果差，效率低下，且安全隱患較大。針對(duì)綜采工作面切眼大跨度頂板支護(hù)難題，采用順山液壓支架加固頂板施工工藝，取得較好的支護(hù)效果。

關(guān)鍵詞：大跨度切眼；頂板支護(hù)；順山支架；施工工藝；支護(hù)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
