【摘要】In the construction of Pingdingshan No.8 Coal Mian Ⅳ-1 mining area Ⅳ5-6-11050 cuts eye once forming roadway and sub completion roadway,research and design for Ⅳ5-6-11050 cuts eye support parameters and construction techniques,through observation,inspection,roadway support parameter effect analysis conclusion,reached full section the construction into the lane to achieve a large section cut into safe,efficient and fast lane construction,by contrast with sub completion roadway,the roof support stability,no obvious subsidence and deformation,achieved good results.According to the effect of supporting the summary of such geological conditions under the large section of the construction of a cut into the work experience,for the provision of such conditions to achieve a large cross-section of a rapid roadway into the experience.%在平煤股份八矿丁一采区丁5-6-11050切眼一次成巷或分次成巷的施工中,针对丁5-6-11050切眼的支护参数和施工工艺等技术内容进行研究设计,通过巷道围岩观测、支护参数效果检验、分析总结,达到全断面一次施工成巷的目的,实现了切眼大断面一次成巷的安全、高效和快速施工,通过与二次成巷技术对比,顶板支护稳定,无明显下沉及变形现象,取得了较好的成果.根据支护效果总结此类地质条件下大断面施工切眼
